they're a long-term problem so laurel is gonna start this video for us and then we'll we'll come back and chat a little bit more this month on our land we talk about the rio grande what's happening this year but into the future as scientists learn more and more about what will happen to the river and its reservoirs and the rest of us who rely upon this water as temperatures keep rising and we keep having difficult conditions the impacts of climate change don't just reflect one dry year or one bad season they intensify one another they build on one another we see this in our forest our rivers all across the state one place where it's plain to see how warming plays out in our arid state elephant butte reservoir in southern new mexico it's sad to say that right now we're at about nine percent capacity this this reservoir can hold over 2 million 200 000 acre feet of water and in my tenure with the district i've seen it spill over the dam and i've seen it as lower than it is right now so it's an unfortunate thing but when you're in the west droughts happen and we're in a mega drought right now the cattle drought gary eslinger started working here in 1978 for the elephant butte irrigation district today he's treasurer and manager responsible for bringing water to more than 90 000 acres of pecans alfalfa chili onions and even cotton through hatch and down to the messiah valley last fall the district told farmers not to expect much water from this reservoir on the rio grande they're anticipating that this could be the worst season in memory most of the farmers in this valley are pretty familiar with where we're located right now and they come up here and they can see the same thing so it's not any news to them that we are short of surface water we've been short for you know going on 20 some odd years to survive farmers have to adapt they pump groundwater or they fallow fields to use what water is available for higher value crops i'd hate to see it go away i hate to see agriculture just diminish especially here because it's it's a great part of this valley from from here all the way down to to el paso it flourishes and and you think about it and it's got a great economic benefit to this entire state like many dams across the west elephant butte was built by the u.s bureau of reclamation dagmar llewellyn is a hydrologist with the agency but now we do it in a more what reclamation did from the beginning and is is charged with is taking what can be an inhospitable landscape for human activities and finding ways to make it so that we can thrive here right that's what we did in the past by building dams that was the the action that we thought was needed at that time the agency has evolved though and i believe that the programs that i work on under the secure water act are what enable us to do the same thing now which is to try to find ways to take what's becoming a more and more challenging and inhospitable landscape for a lot of human activities and find ways to make them possible and to allow us to continue to thrive here our lives have certainly changed since the early 20th century when elephant butte dam was built and as we've pumped more greenhouse gases into the atmosphere we've warmed the climate there is no new normal we talk about what is the flow of this river relative to the average to the normal but the challenge of climate change is that we're losing the whole concept of normal for centuries farmers relied upon the rio grande as a snowmelt driven system the water you see here predominantly originates in the mountains of colorado and northern new mexico and it builds up over the course of the winter as it snows into a snowpack and that's the primary place where we actually store our water some moisture would seep into the forests some would melt through the spring when farmers need it to sustain crops until the summer monsoons but as arid places like new mexico warm they also dry there so think about how your hair dryer works right you heat things up so that you get the moisture to go into the air it comes out of our soils it comes out of our tree roots it comes out and everything that uses water riparian systems our crops everything all the way down needs more water just because it's warmer just because of the way your hair dryer works eslinger is an optimist in his time here he has seen droughts and floods and he has faith we have to trust mankind and trust our our future to those who will come in here and see new innovative ways to to help um deal with the situations whether it's a drought situation or flood i mean my god if if we had a flood event here and i've seen those i've seen hatch underwater it's it's it's terrible it's just terrible a sight to see is is this empty lake elephant buttes low levels don't just cause problems for farmers here under the rio grande compact until those levels come up and new mexico can send the water it owes to downstream users we can't store water in some upstream reservoirs either and these problems won't disappear anytime soon and we have a river that's highly variable in its flows both within the year and between years and it's just going to get more variable so everything they call it intensification of the water cycle everything is just happening more so the climate of the past that we all came to rely upon no longer offers a map for the future and the better we understand that accept that the better we can know how to face that future for our land and new mexico infocus i'm laura paskus thanks for showing that laurel um so dagmar you are a hydrologist with the u.s bureau of reclamation we've talked so many times over the years but i'm wondering if you could just help the audience help us understand this morning just briefly describe the work that you do specifically here in the rio grande basin sure thank you laura it's really a great pleasure to be here with you all this morning um as laura said i work for the bureau of reclamation here in albuquerque and i have the privilege of of um having my job be to use science to help us figure out how to do how to serve the public here better and we do that by improving the ways that we monitor the system where all the water comes from and where it goes and how we um forecast what's going to be coming in a particular year we study the snowpack so that we can understand better how much is accumulating how much actual moisture there is in that um so we try to understand try to use science tools to understand better all of the components of the hydrologic cycle and then use models to see how those all link together and unders and see if we have a good understanding of the processes that link them together so that we can put all those pieces together and then work with the community to try to make tr to try to envision what our future might look like and work together to to see how those visions might play out over time without actually having to do the kinds of changes we can we can we can run them through our models and see what the implications of different kinds of actions infrastructure or policy changes or your community activities might affect the overall system so one of the things that i really appreciate about you dagmar is you're doing the science um but you're such a great community member you know you show up to panels like this i've seen you give countless presentations around new mexico and so um as you'll see from this very short clip that laurel is going to play right now um dagmar is excellent at talking about climate change and breaking things down into manageable bites of information so here in this video she explains very briefly climate change and its challenges there is no new normal so we talk about what is the flow of this river relative to the average to the normal but the challenge of climate change is that we're losing the whole concept of normal so as i said our challenges are basically still the same ones they were before it's arid it's variable but it's becoming more so um so the challenge to us is we we built our cities knowing sort of what a 200-year flood is and we can keep our houses out of that right or you know we build we build any of our engineered infrastructure kind of looking at what the what the heat's going to be what the floods are going to be how deep the droughts are going to be and then add some sort of safety factor and construct these things it's a lot harder to operate when you don't have a normal we have this much snowpack this year what's that relative to what we expect like you don't have that normal to fall back on anymore um and so yes if there's one last thing i'd like to say is um let's get away from this concept of what's the new normal because the real challenge for us is finding a way forward in a system that no longer has a normal so yeah i mean dagmar is so good at explaining these things here we have her on the side of the river and she breaks it all down beautifully um so let's talk a little bit more in depth about some of these changes and challenges the rio grande often dries in the stretch near san antonio new mexico this happens you know pretty frequently in the summer for pretty long stretches 10 20 sometimes 30 or 40 miles and last while the rio grande got very low even in the albuquerque stretch we were kind of watching that happen in the um in the fall last year what do you anticipate we're going to be seeing this year dagmar first first the first thing that i want to say is that the the rio grande is a highly engineered system and so what you see in the river today doesn't necessarily reflect whether it's a good year or a bad year right um so this year we're seeing we're seeing quite a lot of water coming down through albuquerque on the on the rio grande and uh many of us have been out recreating on the water this year um it's really quite lovely out there um but really what that what that reflects is the fact that um we're short of water oh my god silence this excuse me my apologies um i thought i wrote to everybody to keep that from happening um what it reflects this year is that the uh last year we had a tough year and um the state of new mexico actually provided some water that we had in storage upstream to farmers um rather than running it all the way down to elephant butte for storage for the rio grande project the elephant butte reservoir where um gary esslinger gary esslinger works um we we evacuated it from the upstream reservoir because we're anticipating doing some construction there but we the losses would be too high to bring it all the way down so this year what we're doing is running it all the way through the system and um storing what's needed for the rio grande project down in the messiah valley las cruces down to el paso but not storing water upstream that's going to be used in the middle rio grande so what we're going to see is quite a bit of water moving through the system in the spring and then not a lot left in the summertime and there is potential that we could even see some drying in albuquerque we do a lot to prevent that from happening but we just may not have the water at all this year to be able to prevent it so like you mentioned the rio grande is this really controlled and regulated system and so i'm curious what are some you mentioned like the elephant view irrigation district and farmers in the middle rio grande kind of what are just some of those considerations that these different management agencies like reclamation have to be thinking about whether it's a good year or a bad year i i'm sorry i'm not quite sure what the question is so i think you know kind of when we look out at the river we think oh this was a there was a good snow pack and there's tons of water coming down the river or a bad snowpack and not enough water but like you mentioned the rio grande is this like very controlled and managed system so what are some of those considerations that water managers have to be thinking about in terms of like turning the various spigots off of the reservoirs and moving the water it's not just mother nature right it's definitely not just mother nature um first and we're seeing this this year the amount of water that we have as snowpack upstream does not necessarily translate to to stream flow downstream so um as we talked about a little bit earlier there there is um poor soil moisture from previous years a lot of really hungry riparian plants along the way as well as hungry crops up in colorado um and so there was a near normal snowpack in the san juan mountains at the headwaters the rio grande and we only received 40 percent of our average supply coming into new mexico so that's a product of those low soil moistures and the structure of the rio grande compact so there's a physical component and then there's a legal component the the legal component says that if the water supply that actually reaches some index gauges in colorado is lower than normal then the proportion that goes on to new mexico is also lower so we don't even get the same ratio of that water and the same thing is true for what we have to deliver from new mexico down to texas they get a a smaller proportion so there's there's less making its way downstream um another thing to consider is that then our primary storage reservoirs are not on the main stem of the rio grande they're over on the rio chama they're also about five days travel time upstream and so there's it's it's some really complex um sort of calculations and uses of models in the water management agencies to figure out how much to store in those reservoirs and how much to to send downstream to create flows or provide water supply to farmers or cities in the in the um in the in the middle valley based on you know what they're seeing at a given time is it going to rain is there going to be more snow we don't have storage reservoirs along the main stem of the rio grande we have upstream of elephant butte we have we have cochiti reservoir but its primary use is is um for flood control so each of those reservoirs has a distinct purpose that congress authorized and we can only use them for those purposes so it's a it's a bit of a game trying to figure out how to maintain flood control space in some reservoirs store water in other reservoirs and um and have this long travel time before the water gets downstream so there's a lot of really complex thought negotiations between agencies that's always going on to manage the flows so somebody recently said to me something along the lines of um oh boy this year was a shock really took farmers by surprise that they're being asked to follow their fields or consider following fields and honestly dagmar i wanted to pull my hair out because i thought this wasn't a surprise the planet has consistently been warming by degrees the climate change and its impacts shouldn't should really not be a surprise to most people um i realize that climate change as an issue can be spoken about politically um and people have various opinions about climate change but the impacts that we're seeing are not really a surprise and so i'm curious you know maybe we get through one bad year maybe we get through this year um but all of these impacts compound upon one another so what do we need to be talking about and thinking about into the future as we see bad year after bad year maybe interspersed with a good year but well first i want to thank everybody who's here today for taking a saturday over the holiday weekend to educate themselves about these issues and you know i will say my experience here in new mexico is that we do have a fairly educated population about our water challenges because aguas vita and it's a it's of concern to all of us um something that you and i have been discussing recently that i think is worth bringing up here is the fact that the water management agencies with all that sort of you know um complex negotiation and modeling and and monitoring of different system components that we do has been effective in preventing a lot of the um water supply shortages and and you know problems within the system that we might have seen otherwise for example a couple of years ago in 2018 after july 1st there was no water left in the in the rio grande system there was no water coming down from colorado effectively there was some maybe some spring water coming in there was no storage left of rio grande water and so at the bureau of reclamation um we worked with the the albuquerque bernalillo county water utility authority to access and basically the federal government purchased some some water that the uh that had come in through the san juan chama project imported from the colorado river basin and stored at a reservoir up on the chama and and basically the federal government year of reclamation purchased that wet water from the city's water supplies and ran it through albuquerque so that the people in the city didn't actually see that we were completely out of water and so you know that's good in that it preserves the ecosystems and it provides water supply to farmers and cities and it's it's useful to do but i've been realizing lately that it has an impact when we get to the the sort of the the resilience threshold of her ability to to take those actions that that um sort of preserve the system even when we're really in dire straits um it might prevent the you know the people who are paying some attention but really aren't involved in those background fuels they're not backroom deals but those uh um you know complex negotiations from really seeing how challenging things are getting we've we've done our best for as long as we can and then suddenly we get to a year like this one and we say oh actually it's worse than you thought and we're gonna you're gonna have to not plant this year and so i think we can do better with messaging about um what we're doing behind the scenes to try to keep the system operating even when conditions get really challenging so i wanted to touch base just a little bit you're also involved in some research looking at monsoons um and i would love to hear a little bit more about that because we you know we we care about our snowpack we care about our monsoons so what's the research you're doing and and what are we looking at into the future do you think this has been this has been real some really interesting and exciting work um over the over the course of my you know the time that i've been working on water management issues in new mexico so that's the the last 21 years um we've always the national weather service would officially call the monsoons the forecast for the monsoons a crap shoot really just it's it's not something that we've developed a good ability to forecast and um it's a key part of our early water management decision so we're looking at how much water is coming down off the snow pack and we say well if we have a good monsoon we can store this much upstream for the middle rio grande farmers but if we don't get it then we better have that water in elephant butte right and so there's these sort of complex negotiations that happen because of the need for information about the monsoons early that we just haven't had um so i'm and i also became interested as i was learning about the you know the ways that we project impacts of climate change into the future that the ways that we did that um one of the things that we kept doing is as we sort of bias correct and downscale these big global models down to the local systems we keep sort of tying them back to how things were historically and so if there were going to be changes in extreme events within our system such as intense monsoons or even remnant hurricanes they would be masked by this process and i thought there must be some way that we can really see first we can start to forecast the monsoons on an annual basis but then we can start to figure out how they might change into the future and whether that's a potential water supply for us because just logically um the the monsoons are caused by a contrast in temperature between the land surface and the ocean right um and if the oceans are warmer then the more moisture can be drawn into the air and then that contrast as the land heats up which it's doing will suck those thunderstorms in and that's how we get our monsoons so there is some thought that that there's a lot of complex variables in it that have to do with our topography and where the polar jet is and expansion of the hadley cells and all these kinds of things but there is some potential that we could get maybe more water supply out of it especially if we could start to forecast it so i started working on a project with the national center for atmospheric research looking at that using some statistical processes and extreme value theory um just to try to see if those extreme events and the intensity of monsoon is changing and then we use this um tool developed by andreas prine who a researcher up there called weather typing so the we've been saying that the future projections can't really capture all the process intricate processes of the mussoons and their interactions with the mountains and those kinds of things but what he's done is he's looked at the whole continental united states and and looked at what kind of weather patterns set up in terms of low-level moisture in the position of the jet stream and the temperature of the oceans and all of these kind of large scale phenomena to see under which of those conditions do we actually get a monsoon and what some preliminary research he's done with that has suggested and and the signal seems to be pretty robust is that our monsoons are likely to decline until say the mid 2040s and then actually go upwards in the later part of the century and we haven't quite figured out why we're seeing that signal yet it could be something having to do with the the melting of sea ice in the arctic it's you know it's something it's a it's a global phenomenon that's changing these big parameters that set up that that weather typing but it does seem to suggest that later in the century we might get more monsoons and be able to use that as a water supply to make up for the fact that we're likely losing our snowpack so as you were talking about that i was thinking about there's so much changing and you know we see in certain places where there's like these these feedbacks where where one thing happens and it creates a unanticipated consequence in some ways and i'm curious like how do scientists incorporate that uncertainty into their models and then how is that uncertainty incorporated into things like on the ground management yes certainly there's there's a lot of uncertainty associated with projections of of trends and future climate conditions the la but the largest source of uncertainty we have is human behavior we we really just don't know how humans are going to live on the earth in the future what their energy sources and use levels are going to be and so what we wind up doing with the projections of future conditions is running a number of different scenarios so here's what things might look like if humans get their greenhouse gas emissions under control really quickly um versus whether we you know burn down all the rainforests and use huge amounts of fossil fuels and and then try to run model scenarios about how our individual locations will um sort of experience changes under all of those different scenarios then at the local level we basically do the same sort of thing so we'll take those projections we'll run them through models with the current development condition so meaning the current population and the you know the current irrigated area land use characteristics those kinds of things run them through see what the impacts of of the sort of global changes are going to be and then we can run that same sort of scenario planning ourselves so what if the population you know goes up really high because everybody realizes they want to live in new mexico versus what happens if it just gets too hot and we have some mass migrations out and we can see how our um how our local system and its water supply might play out under those different kinds of conditions so really what we're trying to do with all of this uncertainty that primarily is because of uncertainty about humans is tell different stories and work with other water managers and the community to see how we might respond to those different kinds of stories right and then think about how we get to those stories and then what we might wanna what we might wanna change amongst the human drivers so we've talked a little bit about farmers and i'm glad you brought up the idea of migration also either into the state or out of the state i wanted to switch gears a little bit away from people what are we thinking impacts this year and into the future on endangered species like the silvery minnow or even you know fairly robust species like our cottonwoods in the bosque how do these decisions how does climate change affect all of these non-human species yes well certainly um those species those species that you mentioned are are what we call conservation reliant species and what we mean by that is that they probably wouldn't survive without us taking action on a regular basis to help them survive and that that's unlikely to change and the reason for that is that we've fundamentally altered so these are both you know sort of species that are that were predominant in the middle rio grande we fundamentally altered the processes along the river so that it no longer favors them relative to other species that have come in come in later catfish and carp or or whatever it is um or tamarisk in terms of the in terms of the riparian species so what we've done is we've we've capped off the peaks of our hydrograph that come with the spring snowmelt runoff put that water when it's available into our reservoirs and provided a more steady supply through the middle rio grande that's that sounds like a great idea it doesn't flood up to fourth street every spring and everybody's houses get flooded we can have our city here there's you know there's a there's a lot of reasons that that's a good thing but those species both the silvery minnow and the cottonwood rely on that disturbance regime that overbank flooding um to provide places where they can reproduce so the cottonwoods need some overbank flooding to bring moisture into the onto the riparian system where they grow and a slow gentle recession of that so that their taproots can follow it the silvery minnow also um reproduce in sho in slow moving warm side channels right and those kinds of things form even in the overbank when it floods and if we stop doing that then they can only reproduce in the sort of swift main channel then their their eggs and then the larvae and fish that ultimately come from them um will probably get washed downstream say to elephant butte reservoir and so it's because we've changed the fundamental operating system of the river that they're that they're challenged they're pretty robust species if we if we continue in that regime but we've altered it so i know during discussions like this people always come to me at the end and say what can we do you know and i think i'm curious what you have to say about that about individual actions what we can do in our homes that are in our farms but also when talking about this sort of structure that we've imposed on the river is there is there any hope for us to change that structure in the future so paul tashan from audubon just gave a really interesting talk about this this week i think you were there um and he was talking about um el rito grande or el poco grande some name like that implying that what what we can do if we put a concerted effort into it is recreate those same structures um and processes that have allowed the cottonwood and the silvery minnow um southwestern willow flycatcher some of the other species of concern to thrive but do it on a smaller scale right and so maybe we're not flooding up to fourth street every year we're flooding within our levees that protects our community but we still can sort of release water from our reservoirs for example in order to mimic those past processes but allow them to occur on a smaller scale and so so that is something that can be that can be that you know when you say we we as a community can take action towards um and i know paul is leading a group called the isleta reach stewardship association where they're trying to look at the ways that those kinds of changes in the hydrograph might help to implement some of those processes within that reach that's under reclamation funded under reclamation's cooperative watershed management program and a lot of watershed groups are being formed to tackle these kinds of problems through in different sort of portions of the rio grande throughout the system from up in the up in the headwaters up in colorado on the rio chama and um and then down through through the different portions different reaches of the rio grande in new mexico um so in a general sense when people ask me that question about what we can do um from you know for related to greenhouse gases or related to the impacts of those greenhouse gases any of these questions um my answer always falls along the lines of build community build community is the the strongest thing we can do our individual actions to ride our bikes to work and recycle and all of those kinds of things have have limited impact individually but collectively they have they have more impact and they they set examples and they give us opportunities to show leaders of the ways that we can change the system in a in a larger way i think it's always important to um have those communities also share resources so you think about with saving water if we have community green spaces where we can all go and meet together outside and safely and all of that um then we have less need actually to have manicured lawns in our own yard like humans need these kinds of lush green environments but we can have them in collective spaces and therefore have fewer of them so it's just another reason that we can that the building community um helps save water it also helps save resources we can have each other's backs we don't all have to have our have our own um you know power tools or you know whatever resources we think we need we can we can share them as community and overall have everything we need have each other's backs and not and not have quite as much of a need for material goods through the building of communities i love that idea of community um especially during this past year um absolutely just seeking out one another for company for sustenance and to envision a better future not just for ourselves and our human communities but our rivers for example i really love that idea i live close to a community farm and i'm not a part of it but i love going by it every day and seeing how that has really grown especially over the past couple of years are there other ways just we're kind of in the last couple of minutes here of our discussion are there other ways that you find hope or excitement for the future that even though there are all these great challenges for us maybe to be a friendlier species toward the rest of the rest that we share the planet with that we share new mexico with so i work i work very hard at the bureau of reclamation i'm always working long hours but every time i'm offered to an opportunity to teach at the university of new mexico and i've taught in civil engineering and geography and at the law school i take it because i derive that hope from the youth in our community i just see so much energy and so many new ideas within that group of of people and i see i see really really new and innovative ways of looking at the ways that we can thrive here in this challenging environment as i said on the video um in in those young people and that's where yeah that's where i derive my hope and i think there's plenty of them here today and thank you for for being here and for and for giving me that hope to cling to right um so we're gonna switch gears a little bit there are also you know climate change is a big issue um drought and dryness and ridification big issues but but we also need to think about regulations we had our recent new mexico infocus segment about the pueblos of laguna and jemez suing the army corps of engineers in the u.s environmental protection agency over clean water rules and many of you are probably familiar with the waters of the u.s rule an obama era rule that was then changed quite drastically during the trump administration and implemented last summer and it weakens or eliminates protections for um ephemeral or intermittent waters which in new mexico account for you know something like 85 or 90 percent of our waterways so in the segment you're going to watch right now we're talking um with chris toyah from the pueblo of jemez and cliff via at the university of new mexico school of laws law clinic and they're going to talk a little bit about clean waters of the u.s rule why these tiny waterways are important for new mexico and what this lawsuit from the two pueblos is all about so i will turn it over to laurel so there's been back and forth for years now about whether or not to protect small waterways under the clean water act and last summer the trump era rule took effect that essentially the u.s environmental protection agency and the u.s army corps of engineers will no longer protect certain types of waterways under the clean water act now the pueblos of laguna and jemez have filed a lawsuit against the two agencies regarding this rule let's start with you chris toya you're from jemez pueblo can you talk a little bit about why these ephemeral and intermittent waterways are so important to new mexicans because we live in the high desert southwest 87 percent of our streams are ephemeral meaning that during the monsoon season or rainy events or snow melt these arroyos drainages get filled with water and they are tributaries to the main hamish river and we use the the water for irrigation of our crops and then it's a means of food supply as well we go fishing and the fish that we catch in the hamish river is what we eat uh one other important factor is that the water in the jemis river is used in ceremonies and uh this is a threat to our way of life cliffia you worked on this lawsuit through the unm law clinic can you talk a little bit about what types of pollution what types of threats these sorts of waterways are under and if successful what this lawsuit would would do yeah thanks laura so through the unm school of law clinic we have worked with a number of tribes and tribal members for a long time and we listen to their concerns and we think about how we might be able to use the law to address those concerns one of the biggest concerns we've heard recently was concerns about continuing to protect tribal waters under the clean water act the clean water act is incredibly broad it basically applies to all pollutants um you know toxic pollutants hazardous waste even in some cases things like dirt um or cow manure and so the threats to new mexico's waters can come from many different directions but one of them might be something industrial activity like mining um including uranium mining uh in the navajo nation in the grants mine district um there's pumice mining and in the jemus watershed um there's sewage raw sewage has been a big problem across the country for a long time um so and even things like sediment that might clog up a channel and prevent waters from reaching the communities could be an issue and is something that is regulated under the clean water act when the clean water act applies that the problem here is that the trump rule severely diminished the scope of protection under the clean water act so the federal administrations have gone back and forth on these protections and even states have gone back and forth under the martinez administration the state of new mexico opposed these protections cliff let's start with you can you talk a little bit about why protections under the clean water act would be controversial well i think part of the controversy is you know resistance to federal regulation at all the clean water act was designed to be to establish national standards that states would implement and so there's always been sort of a state component there i don't think that's been fully understood but i also think that there's been a lot of misunderstanding about what the clean water act does one of my favorite examples of misunderstanding was there was a rumor that obama was attempting to promulgate a rule that would regulate puddles under the clean water act and so the obama administration actually went out of its way to write a rule that said this rule does not apply to literally puddles and the first thing that the trump administration claimed um after a trump came in in 2017 was that obama's rule has been a disaster he used that word and he said in particular is it is regulating puddles um when obama went out of its way to say no the rule doesn't regulate puddles so there's been a lot of misunderstanding misstatements about the clean water act um scope really what it's about is protecting your water and mine waters in the jemez river waters in the rio grande and we have so little water in new mexico that we just don't have any to spare um so maybe there are some genuine controversies around the edges of wetlands in in the eastern united states but all the water in new mexico is needed for purposes here in new mexico and particularly for the tribal communities right chris toya clean water just doesn't seem controversial to me can you talk a little bit about what you've seen over the years in terms of you know wanting to protect these waters and in particular tribal waters yes throughout the years i've noticed that you know we're getting more and more people recreationalists in our hemis mountains you know the forest service declared an area up here in the jemez mountains a national recreational area and we're getting people by the thousands i think annually this is old data but they were saying that we get over 1.6 million visitors in our heinous mountains and the largest bottleneck is the pueblo itself we're getting so much vehicle traffic on the highway and it's dangerous for the people but what people don't realize is that you know they're trekking on the uh on the roadways on areas that don't have any paths you know you got vehicle traffic you got foot traffic and you also got cattle and so what happens is that you know this area start getting eroded and we've noticed within this past few years we're just getting so much sediment in our irrigation systems um it's one issue um that we're facing um and you know we we're farmers and we we use this uh water from the jemis river to irrigate our fields but we're getting sediment loads that is unbelievable um the other issues is that you know we need this clean water as i stated earlier it's water is life and you know it's a water is very crucial in in tribal life especially in ceremonies we use the water from the jemis river water from the springs to conduct ceremonies not only for ourselves but for the whole world in a sense because we we're uh protecting and you know praying for the balance of mother earth and so when that happens you know not only do tribal members benefit but the whole world benefits so lots of different groups have weighed in on this rule on all sides of the issue chris can you talk a little bit about why this is this lawsuit is so important for the pueblos in terms of things like jurisdiction and sovereignty yes you know currently the jemis pueblo reservation is approximately 90 000 acres we only claim uh as far as the boundaries go a fraction of what our ancestors had used at one time so much of the ancestral homelands are under the management of the u.s forest service the department of interior the national park service bureau of land management and private property so the watershed the jemez watershed is uh above the valley of james pueblo and so the main watershed is in the vice caldera national preserve and the san pedro uh wilderness in the nacio mental mountains and so you you have this different uh land management happening from different federal agencies and as i stated earlier we've got many many thousands of recreational recreationalists enjoying you know the mountains and you've got your ranchers with cattle um and uh you know we we need these waters protected uh not only for ourselves but for wildlife for all humanity uh if we don't protect our waters you know we're putting ourselves in uh in a situation where you know if our waters are really polluted then you know we'll be looking back and saying why didn't we do that why didn't we put the effort in to protect our waters um it's it's a very important issue that we're facing today uh tribal tribal people across the united states and all peoples you know we seem to uh kind of have missed uh the point in in being human and being connected to mother earth uh i i think today uh our priorities our business uh and making money but um you know i i hope that eventually we come to our senses and start protecting what is important for for all life right cliff in our final minute here what happens next with this lawsuit well there have been a number of similar lawsuits filed across the country including lawsuit by the navajo nation um a lawsuit uh involving tribes near zone and st washington um what we have seen is that the new biden department of justice has sought to seek a stay of that litigation and maybe that's something that that we would consider as well but we're also very concerned about protection of water in in new mexico right now um and we really need to think about how we we began doing that the bible administration on day one of the inauguration signaled an interest in reconsidering and possibly repealing the trump rule and we would love to see that but that process takes time um it could take a matter of years um to go through the formal rulemaking process so one thing that our litigation is asking for is uh is just vacate the role just take us back to where we were before at that point um the pueblo of jemus the pueblo of laguna can art make the arguments exactly as chris is saying about why it's so important to protect their waters right now we need a new rule and everybody agrees that we do need a new rule going forward but while that rule making process is continuing we would really like to stop the effectiveness of this rule that just eliminates protection for so much of new mexico's waters right cliffia chris toya thank you so much for joining us on new mexico infocus today thank you laura thank you for the opportunity it's a reminder to everyone to put your questions into the chat over at ob so laurel can send those our way um so we do have a couple of questions dagmar this one comes from my boss kevin mcdonald you've been referring to normal in the discussion of current water management planning but would it be more appropriate to say long-term average or what should what language should we be using when we talk about this well certainly we started with the video of me talking about how there is no longer a normal um but we do in terms of atmospheric climate science um we do have something we call average or normal and that is a rolling period of 30 years that that updates every 10 years we just actually had an update so that we dropped the really wet 1980s and added the 2010s so actually now that average normal that we compare to is more affected by the eridification climate change impacts that we've seen um in the basin so far right so i don't know what the right term is a really good question um because we're so i mean everything that we do is so designed on this concept of normal we've had a very very stable climate for the last 8 000 years and um so when we have real drought periods or real flood periods we have a sense that we're going to return to some central tendency that say that stays steady and that's what we're losing but we still need you know there still are some fundamental ways that the climate in new mexico is different from the climate in massachusetts right so we want to be able to tie back to those long-term trends like how things like how long does it take us to go get you know into the the depth of a drought and how long does it take us to come out there's there's certain aspects of the past that we still carry forward um just because of the way large-scale patterns set up on the globe now they're changing too but not they have a little bit more inertia to that change than some of the other processes do and so we're still trying to carry forward some understanding about what we know about how our system functions while acknowledging that it's changing all the time and i don't know the right word for that yeah i'm so struck you know i often am thinking about what's happening right now and looking into the future um and and gosh you just kind of stopped me in your tracks when you noted that for the past 8 000 years you know we had it really good as a species we have this this perfect system basically for us to really flourish and function and we kind of really messed up well the way i look at this and and i i think you've seen some of the talks where i show the the temperature and carbon dioxide history um you know through the pleistocene um growth and retreat of of ice that sort of thing from ice cores in greenland in antarctica and you the pleistocene is crazy up and down swings and then about 8 000 years ago we see this incredible stability and it's both sides of the planet are showing that same thing and um it's been postulated and evidence seems to support that that change was due to humans that was due to humans putting greenhouse gases into the atmosphere that kind of kicked us off that in and out of ice age cycle that we'd been living in and has kept our sort of our populations low and prevented the kind of growth in human population and society that we have today because we're always trying to survive in this ever-changing condition um and so the way i tend to look at it is like a like a high protein diet has done a lot for humans we can get a lot of protein if they're plant or animal source proteins we tend to grow bigger and stronger but there's a point where we get too much and then we get gout right and so so i tend to look at this as kind of the gout phase of humans impact on greenhouse gases on and the environment early on what we were doing helped us to stabilize the client the climate into this this very stable period we've had for the last 8 000 years but now we're putting so much into the atmosphere that that we're kicking ourselves back out of that period into of stability into something that's more that's warmer than but more like the rest of the plasticine in that conditions are always changing and changing rapidly so we just got this great question which was kind of along the lines of something i was going to ask you anyway so i'm just going to read this question directly what does new mexico look like at the end of one of these 12 to 30 year old 30 year droughts that showed up in the last 1500 years and what does it look like if there's a repeat of the drought that started in 1200 a.d what goes away and what survives that's a big question that's a very big question um well certainly if we look at the if we look at the drought of the 1200s and you go around to the the the heel equip cliff dwellings or tachaco those sorts of things what goes away is humans right and we talked a little bit earlier about about migrations um but humans are mobile creatures and we are able to move towards places that are more hospitable to us so certainly that's one of the things that changes but um there are changes in our ecosystems that you know if it of a particular kind of condition even if it's constantly changing but something like drought goes on for a long period of time you know we're seeing this throughout the west and down in australia last year it was terrible what we see is we lose our forests right our forests are sort of stable structures that are adapted to particular temperatures and moisture levels and um what we're seeing is they're burning um now there's there's reasons that they're burning that have to do with our past management and allowing them to get too dense that kind of thing but even without that there's you know we've been working the rio grande water fund has been working hard and you know reclamation's a member of that to to um try to thin the forests so they're not as prone to that real catastrophic kind of wildfire but there it it does the literature shows that there's a limit to that somewhere maybe mid to late century where even with that we're going to be losing our our forests to um bark beetles and spruce budworm and the fires themselves right and so uh you know dave gotzler at unm gave a presentation where it was one of those things where you say well in 50 years your city is going to be more like some other city saying albuquerque is going to be more like el paso um and what's the really striking difference when you look at those two cities well it's that our sandia mountains are covered in forest and the franklin mountains down in in the el paso area are not um and it's not it's not a pretty vision to think about how we get from a forested landscape to it to a not forested landscape um so i those those efforts at thinning are critically important they put off that point but if we continue down that path of extreme warming then we will probably lose our forests so that's something that will be a real fundamental change in our landscape and on our ecosystems and in our ability to store um our snowpack in the mountains right because because it changes the processes of how much water reaches the ground versus how much sunlight gets in and heats them in the springtime right so it changes those water supply processes as well that just that leads to a lot of fundamental change so that you know it's another area where we're doing a lot of work in our planning group at reclamation is trying to understand these these forest and watershed processes how that affects the forest how that affects the snowpack how that affects how if it burns how that affects the potential to be able to even convey water in our river systems um and to maintain the infrastructure that we use say to divert the san juan chamber project water um where if if we lose our fo our forests catastrophically then we've got nothing to hold the sediment together a lot of it might wash down and it might bury our infrastructure and that would mean in one fell swoop we lose our ability to get what is the um predominant water supply for central new mexico drinking water right so you know what's what's important to think about is that any change or any event such as a fire has immediate implications for that system but they cascade all through the system and as we as we look at how our systems are changing we have to think about things like how when when the jemez mountains burned um in the lost conscious fire that led to washing of well manhattan project waste into the rio grande and into sediment slips and landslides that actually blocked the rio grande and we had reclamation a number of other agencies had to get out with big yellow machines to clear that out ash that washed down in subsequent rainstorms then blocked the oxygen transport and and killed a lot of fish also blocked the ability of our santa fe and albuquerque drinking water projects to pull water from the river because we we know how to treat out sinking um contaminants in that water supply so that we can get a clean water out to the people but we're not so good at floating like um floating particulates like ash and so it was you know it's better just to turn that water off and rely on another source in the meantime so there's any change in our system cascades right through and it's important to think about all of those kinds of consequences yeah i've been spending you know the 10-year anniversary of the last conscious fires coming up next month um and i've been spending a bunch of time up in the various parts of the burn scar recently and um and we have a show coming up in june about forests and climate change so everybody should tune in for that but um you know one of the things that since i've been going up to the burn scar on the east side of the jemez like near cochiti canyon that i'm continually struck by and it's interesting that you mentioned dave getzler and the future forests and what the city will look like is you know standing on that east flank of the jemez there which was once a dense conifer forest and too dense you know because of our fire suppression um issues but now you stand there and you are looking straight down into the rio grande valley straight down into cochiti reservoir you can see the drones like not just the the sandias and the manzanos but you can see all the way to the drones down there like it is no longer a forest and um i know you talk about these cascading effects of of fire and sort of all the downstream all the long-term impacts including the fact that you know in our warming world many of these species that have been eliminated due to fire it's too warm for them now um and so we also kind of in thinking about these these different impacts it's it's um we're really good often times in in forums like this and talking about the different ecological impacts and how these how we talk about adaptation moving forward how do we get better at talking about why this is happening and how we need to mitigate say reduction of greenhouse gases how do we do a better job of connecting greenhouse gas emissions with what we're seeing on the ground here with our water challenges so you know i'm a scientist and i do a lot of public outreach um and scientists have a particular way of communicating with each other that it seems it doesn't work for everybody we're we're all trained to convey and receive information in this particular way which isn't how we communicate the rest of the time right so so what i've learned is to talk in stories everybody understands and relates to stories and then um in the last several years i've become really intrigued in the the power of art um and you and i were both participating in the unm art museums there must be other names for the river program um just this week um there as many hopefully many on this call know um they did an art piece looking taking the actual data from the rio grande hydrograph over time and having artists sing it um there was some also the unm resilience institute um had a now we didn't have one last year but the year before had our last annual forum and um i came up with the idea and one of the you know even as a scientist one of the things i'm most proud of of pairing up the the students who are giving poster presentations of their research with artists in the community and having the artists convey what the real meaning to all of us of this of this research should be so so there was a one one phd student who was doing his work on after the conscious fire how the streams are impacted and then how what processes they go to to rebuild and um the artist that he paired with says oh like trauma and recovery i'm all over trauma and recovery i think i can i think i can do some some art around this and they created this multimedia display with with guitar music and spoken word poetry and videos across the four walls of an enclosed room that was so powerful and amazing and i think conveyed that that the sort of the meaning of the changes that are underway in the jemez mountains in a much more profound way than than i can ever do by talking and so i just now i'm just seeing a question that somebody had that laurel sent over for me um about being concerned that discussions rarely focused on what the ipcc has told us in terms of reducing greenhouse gas emissions um and stopping fossil fuel burning and the person asked how can we have this discussion without emphasizing what new mexico can do um regarding mitigation toward this end and i think that that's a great question um not just for this panel but that that we should all be having in new mexico um all the time in every context in my personal opinion just um from covering these various issues and you know new mexico we're in this really interesting situation where we are seeing the impacts of climate change um and have been for quite some time but we also benefit as a state from um the oil and gas industry and so i don't necessarily think we have time for that discussion today but it is it is an incredibly important discussion that new mexicans should be having all the time all the time so i'm glad um that question was brought up it's it's it it can feel a little fatalist to just say here's the changes that are underway and we just have to adapt to them right um and what we we we do also need to be considering how we can change the trajectory we're on and it new mexico is a high impact state but it's also a high greenhouse gas emission state primarily related to methane and the ways that we handle methane but you also bring up another point which is new mexico supports the oil and gas industry in that that's where we get a lot of our state budget um and so there's also efforts underway and there was a lot of discussion in the state legislature this past year about ways to that we can start and need to start diversifying our economy so that we can we can gain um you know well life life-saving um and and community managing funds from other sources and begin that begin that transition ourselves for it's it benefits our own understanding of our role in the in the globe and our own survival yeah one of the things that i think about a lot is um dr jonathan overpeck who we've had on the show before who i'm sure lots of people are familiar with you know climate change is this sort of gloom and doomy um topic but this this in many ways is a very hopeful moment in history i think because as overpack and lots of scientists point out we know what the problem is we know why these things are happening and we know how to slow warming we know how to mitigate you know we have the knowledge it's a matter of political will it's a matter of community decisions um so i always think of that when i get a little bit discouraged about how how big this topic is i'm like oh wait but we have the knowledge and the tools we can't do things we do we need to we need to come together and we need to to find the will to do it um i think that there's a lot of parallels to and a lot of things we have learned from this pandemic that can relate to the ways that we can pull together to find you know i'm not going to say a solution but paths forward in this um in this changing climate and finding ways to work together to change the trajectory that we're on in the pandemic we found we found some some community will and we found a lot of new technological tools um we found a lot of things that we can do to help ourselves get through this and decrease the decrease the catastrophic loss of life that we've been experiencing um it's you know it's a it's been a very severe situation but we're we're finding ways out of it and we we can learn from that and apply what we've learned from that to this climate change both the medication and the adaptation side of it because necessarily our response to the changes that are underway need to include both so speaking of economic diversification somebody was asking about concerns about water usage in light of the coming legalization and adult use cannabis i'm curious what kinds of conversations are happening in the water management community about legalization and growing cannabis in new mexico i haven't heard any discussions about that yet um cannabis is still federally illegal and so we at the bureau of reclamation where i work my understanding is that even if growing cannabis is legal in new mexico um any of it i mean hemp can be um grown within the the projects that reclamation provides water to but i believe that marijuana cannot use reclamation's water resources in order to in order to grow it that's my that's my latest understanding of the situation um so it it we're not expecting that particular legal legalization to really change anything within reclamation's projects and that was how it played out in colorado after their cannabis legalization now hemp is different without the thc um you know that's been actually supported at a federal level through the farm bill and so so that's all that's all right but the the actual t thc cannabis cannot be grown within the federal projects and that's a lot of new mexico's farmlands that is so interesting and i just want to mention for everybody online that um new mexico pbs has an awesome podcast growing forward with megan camerick and andy lyman talk about all sorts of cannabis related issues and i believe they're going to be talking about water in their coming seasons so stay tuned for that um i love this question from one of the audience members how can we make it a requirement that all developers and city planners watch this presentation and explicitly refer to it as they make their decisions i mean how do we get local local planners local city officials county officials how do we get them to pay more attention to water and the intersection of water and land use planning and development you know i think we've i think there's been a lot of interaction we did a um a climate change study um you know that i was involved in with mr cog the mid-region council of governments looking at imp impacts on climate change on on transportation and land use planning we of course worked very closely with with the albuquerque bernalillo county water utility authority and the um the water utility for santa fe city and county so it's very very close relationships and i think that there there is understanding there of the of the limitations of the supply and how that will affect development now there's also political pressures on any kind of government entity um and so they'll be sort of a balance in the direction that they go but i've i've seen these you know much as we you know you hear about things that maybe any community member might not like i've seen those entities make some some really wise growth decisions or that consider water as well so i kind of have one last question from me that i'm curious about because you and i have talked for years and years about these issues and um you know one of the things that we've talked about is that we as a society need to make some decisions and some choices and like the way that i think of it for me personally is is i would like for us to think more about for example how we treat our rivers do we see them just as as something that serves human needs do we think of them as as something that have their own rights and the rights to their own water um how do we how do we come together to kind of make these decisions and choices and then how do we implement them do you think i think i think that's what we're doing right here right now right um and i i've talked about the the power of art to to bring people together i there's going there are going to be a lot of trade-offs in terms of our water use in the future and i don't see any path forward that doesn't involve a community conversation about what those trade-offs are going to be um and new mexico isn't the kind of place you know i know from living here where we say well let's just lay the fair let the let the market decide what we want the future of our community and our landscape to look to look like that's not what i see um in the people of new mexico i see people being being very active about it and participating in community dialogues visioning what our future might look like and i see that i see that interaction um from from young people from tribes from people from throughout our community participating in that dialogue and i think that's a i think that's a really healthy thing at reclamation we're just kicking off what's known as the the rio grande basin study lobotos to elephant butte um and the philosophy that the middle earth grand a conservancy district expressed when they when they first proposed to do to partner with reclamation on this work is that that this process needs to bring in all of the different voices from this basin so the people can talk about their their values and what they envision as a path forward together and the very first exercise that we're asking all of the different sectors and parts of the community to do is to is to come up with descriptions of their values and then also from a technical perspective parameters that can be used to measure how well we meet those values right um whether those are enough water for farming or for ceremonial uses or for you know city landscaping or or whatever it is um what are the parameters that say are we are we meeting those values can we can we get there because that's the language then that that allows the community to actually discuss those trade-offs and if we don't go through that exercise then we'll then we might be talking past each other and so we think that that's a really important way to start this process that values discussion in a large community ensemble of people who care about this issue the future of our water supply the future of our rivers and ecosystems and the forests that support them so i know everybody this is all really heavy stuff and i don't want to leave you overwhelmed um thank you to dagmar for joining me this morning and thank you to all my colleagues at new mexico pbs and thank you all for spending your morning with us um but i don't want to leave you feeling overwhelmed last fall the our land crew made um the episode we're going to show now kind of as a love letter to the bosque and to our audience going through a pandemic going through climate change like we just needed we needed something and so um a huge thank you um for this episode in particular about all of our episodes to the production crew this show that you're going to watch right now um worked on by kevin maestas benjamin yazza anthony lostetter and a big thank you as always to my colleagues kevin mcdonald and matt grubs and so i will pass it on to laurel to start our final video in the bosque along the rio grande throughout the spring and the summer we seek out the cottonwoods for shade rely on the river for sustenance to water our fields or to cool our bodies from the noonday sun and the autumn we celebrate the brilliance of the cottonwoods when their canopies fire the riverbanks with yellow but by late october especially as night starts falling earlier it's easy to take the bosque for granted or to stop blocking beneath its canopy altogether but i think it's the best time of year to be here as the trees drop their leaves it's easier to spot porcupines napping in cottonwoods and elm trees or gnawing on bark or finding the seeds of russian olives in the sands along the bank you can see where beavers have lugged branches dropped into the current of the river or excavated holes to reach the tasty roots of tamarisk seedlings beavers themselves are hard to spot but there are signs of their industriousness everywhere coyotes call out earlier in the evening celebrating their hunt or maybe just singing to the night massive mobs of crows that winter in the middle rio grande valley their numbers too big to even calm murders roost at night in the bosque they spend their days spread out across the city feeding and then return to the bosque at night hundreds of them settling into the trees walk through their ranks and they'll yell at you drop nuts and small branches on your head too and of course late fall is when the sandhill cranes return to the valley for winter today we appreciate their primordial calls and the clunky grace of their landings in the river where they shelter for the night away from predators they've migrated here for thousands and thousands and thousands of generations their habits as clear as the layers of limestone in the sandia mountains their patterns tied inextricably to the sway of seasons today watching the cranes along the river it's something to imagine the blessing they must have been to the people who lived alongside the rio grande for centuries to think of their mass arrival along with snow geese precisely as the weather turned cold and harvest season past like new mexicans the bosque the rio grande they are resilient this river has flowed for millennia these cottonwoods have stood since the 1940s the forest the wildlife have all survived the press of more and more people more and more demands but as the region warms as the region dries and everyone and everything demands more water we also need to demand more for the river more for the bosque and remember this too is our home for new mexico in focus and our land i'm laura paskus thanks everybody for joining us for this morning science cafe i so appreciate laura pasquez for making all these um videos for being our environmental correspondent and thank you also to dagmar for joining us this morning this was an awesome science cafe i appreciate you guys so much thank you and we also want to thank the audience for joining us this was great to see everybody have a great weekend you guys happy memorial day don't forget to join us for our screening on memorial day morning if you're interested in dance as a way of dealing with ptsd i love what dagmar said about the arts by the way goodbye everybody happy weekend
