December 9, 2023
State Engineer Kevin Rein is retiring at year’s end and agreed to join The Valley Pod podcast for an interview with host Chris Lopez before he departs. We’re calling it an exit interview.
In it, Rein talks about the importance of bringing sustainability to the unconfined aquifer of the Rio Grande Basin, how the economic future of the San Luis Valley and its agricultural industry is at stake without a sustainable aquifer system, the unique nature of the Rio Grande compared to the Colorado River Basin and others, and the urgency of achieving sustainability in the face of prolonged drought and climate change.
“I wish there was enough water for everybody, but we developed agricultural and municipal uses in a state that is largely a desert and it often has an abundance for a couple months out of the year,” Rein said. “I think it’s good for us to at least feel comfortable that we have that structure in place. But the other thing we need to know, as I alluded to, is that that structure is going to cause us to make difficult decisions, especially as we see climate change, the effects of climate change reducing our water supply, and we see our demands grow.”
Here’s an edited version of the conversation. The full Valley Pod episode is here.
ALAMOSA CITIZEN: Thank you again for giving us some of your time as you exit. And again, congratulations on your retirement. Is the stress of the job starting to subside?
KEVIN REIN: No. The stress, if we can call it that, is not subsiding at all. This trepidation that I face with the idea of retirement and ending a job that I really love doing, weighs pretty heavily on me and wanting to get in every last bit of good work I can do. That’s weighing on me. Yes. Yeah, it’s very important for me to try to finish this. We’re doing as much as I can.
AC: We want to start with some local issues with you of the Rio Grande Basin and then stretch more into the role of the state engineer for Colorado, if you don’t mind. First, can you sum up the importance of the upcoming year 2024 and the influence upcoming water court trials will have on the Rio Grande Basin? And we’re thinking specifically of the water trial around Subdistrict 1 Plan of Water Management, the alternative plan for operating in that particular subdistrict with the Sustainable Water Augmentation Group court filing, and then the idea of the U.S. Supreme Court weighing in on a new settlement between Texas, New Mexico and Colorado when it comes to the Rio Grande Compact. 2024 seems like a significant year in water court.
REIN: It’s going to be very significant that affects the people in the Valley to greater or lesser degrees depending on those three items that you just mentioned. And so that is critical. And Chris, I’ll apologize to you and the listeners that I’m going to be very cautious about my comments on these because of the legal implications and the fact that it’s really active litigation in three areas and regarding the lawsuit on the Rio Grande Compact with Texas and New Mexico. And then as you mentioned the United States, I will probably not say much at all about that because the facts are there and I don’t want to step in front of our good legal staff and say something that is not quite true to the case in terms of the legal implications of what’s going on. But when it comes to SWAG and that case and the groundwater management plan containing the plan of water management for Subdistrict 1, those are very important issues. And I will admit that I’m going to be a little guarded in my comments about those two because pardon me, as you know, the SWAG case was dismissed, but they have re-filed and we may see that play out in a similar fashion. And without saying too much about that and the groundwater management plan for the subdistrict, from my perspective as a state engineer, there’s one critical aspect of that for both cases and that is the sustainability of the unconfined aquifer. As we know, that’s a difficult component of groundwater management in the Valley because we have a statutorily required sustainability objective. And that has found its way into the rules and into the groundwater management plan for the subdistrict. And I’ll speak to the existing groundwater management plan that’s in place right now that has a deadline of 2031 to meet the objectives, the sustainability objectives, that that very plan sets out. As we all know, and I’ve been on record through letters and public comments, that it’s going to be very difficult to meet that sustainability objective under that existing plan of water management. And I know that the subdistrict has worked hard toward an alternative in this current plan that I approved and is before the court and the way that plays out is going to be so important to the irrigators in the Valley under the rules under their annual replacement plans. And I look forward to seeing the resolution of that. Obviously I won’t be the state engineer at the time and I’m not certain to what extent I personally will stay involved in that, but it is critical to get resolution on that for the irrigators. And since we are under active litigation, if I can use that term for the groundwater management plan component of the plan of water management, I’ll stop right there, but I will mention that as we know, the SWAG applicants have also attempted to address sustainability, at least in their previous application they did. That was dismissed. And for this upcoming application, I’ll admit that I have not reviewed that in detail yet, but that will be also very important to properly review and respond to sustainability objectives in the upcoming SWAG case.
AC: Why is it important for the water court to be dealing with these particular issues now? Can you address the importance of the court doing its work in 2024 and what’s the best scenario in terms of how the court adjudicates these trials or deals with these cases?
REIN: The importance of the water court’s involvement now is because the issue is important now in 2024. The reason it’s important right now is because we’re currently working under the 2031 deadline, and that seems, it doesn’t just seem it is seven years away, it seems like a lot of time, but as we know, we’re under sustained drought in the valley and obviously the economic future is at stake. We can’t just shut down production. So we need to find that way to address sustainability now. And as I said, we’re under sustained drought. There’s no confidence I think from anyone in saying that that will turn around and end. You have to assume a difficult case scenario. And with that seven years is not a lot of time to make up the perhaps 1 million acre-foot gain that would be necessary to get to the sustainability standard. Therefore it is timely.
AC: Do you think groundwater users as a whole in Division Three are making good or reasonable enough progress in solving our water security challenges and what stands out for you there?
REIN: Yeah, so a broader water groundwater availability use challenges, and I need to break away from this sustainability discussion for a minute and just talk about the efforts of all the water users through seven subdistricts under the rules in the Rio Grande Basin. And as we know, the rules that became final in 2019 and are now completely applicable do hold the water users to a high standard. It’s a standard that we have statewide. It’s a standard that came out of our 1969 water right Determination and Administration Act that we need to administer groundwater in conjunction with surface water in the prior appropriation system. That’s what came upon the water users in the Rio Grande gradually over the last 10 to 15 years, but again, in 2019 and certainly a couple years later, finally hit them. And what they have done is developed very comprehensive, very complex annual replacement plans that allow them to pump and comply with the law. What is compliance with the law? Basically it means replacing depletions to the stream system in time, location and amount to prevent injury to senior surplus water rights, and obviously the stay of compliance with a compact. And let me just say quickly, we have a unique situation in Division Three, the Rio Grande Basin, that instead of replacing depletions, they can enter into forbearance agreements to just compensate financially for that. But that’s what they have done to respond to this groundwater challenge is they have developed these annual replacement plans, they have gotten their sources of replacement water, they operate according to the Rio Grande decision support system to ensure that their depletions are properly recognized at the time, location, and the amount so that they can be replaced. I think it’s very gratifying. I wish I could take more credit, but I think it’s very gratifying that the water users, excuse me of the basin, have responded as they’ve needed to, but responded in such a complete and detailed and verifiable way. And I really can’t say that without also addressing the division of water resources staff in our Alamosa office, Craig Cotton and his highly competent staff, they’ve just put in countless hours to analyze and verify and approve these annual replacement plans. Without those, the wells just simply are not pumping.
AC: I want to ask you one more question about 2024 and the Rio Grande Compact because there’s a lot of people scratching their heads around the federal government’s opposition to the negotiated agreement between Texas, New Mexico and Colorado is also a party, too. And I just wonder if you’ve figured out the federal government’s motivation in that case?
REIN: Chris, that’s a very good question and if you don’t mind, I’d like to just not answer that because of the legal implications and I leave those questions to our attorney general staff.
AC: No, I appreciate that. One of the issues or one of the programs right now is the Groundwater Compact Compliance Fund and the $60 million that was put into that fund through Senate Bill 28. What should be the overall outcome of that $60 million for both the Rio Grande Basin, the Republican River Basin as it’s spent? What’s the expectation and what is the advantage gained by spending that money on those two basins?
REIN: The ultimate outcome for both basins is similar but distinct and the mechanism by which those outcomes are realized is also pretty similar. But let me just start with the end game. The outcome for the Republican River Basin, first of all, is to assist in the retirement of irrigated acres to comply with a 2016 resolution entered into by the states of Kansas, Nebraska, and Colorado. And it’s tempting to get into great detail, but just let me say at a high level that part of compact compliance in the Republican River Basin is operating a compact compliance pipeline to deliver water at the state line to make up for overuse of Colorado’s allocation in the Republican River Basin. That works well except for a detail that not all the water is delivered exactly where it should be. And to deal with that, the three states entered into a resolution that among other things, allows a consideration that Colorado is meeting the compact. If Colorado retires 25,000 acres, this began in 2016, by the year initially 2027 but now 2029, with that background, how to retire 25,000 acres, it’s very difficult because people own land, they have water rights, they want to continue irrigating. So it’s through funding. The funding is difficult, you’re assessing fees, you are asking people to help fund this out of their economic development. Senate Bill 28 for the Republican (River Basin) then brought that $30 million in to help fund the irrigated acres, the reduction of irrigated acres, and it’s just purely economic incentive. People want to do the right thing, but it’s very helpful to have that economic incentive. So thank you for letting me go into some detail, but that is the outcome. The desirable outcome is to stay in compact compliance by tying that 25,000 acres in the south port and it’s working well. We’ve met an intermediate goal for the Rio Grande. It is a similar situation as you know, with great interest toward meeting sustainability obligations in the unconfined aquifer, but in general throughout the basin, reducing groundwater usage. And then to do that, and let me just go back specifically to our sustainability discussion in the unconfined aquifer. Subdistrict 1, reduce those irrigated acres. Their current plant of water management has a goal of reducing 40,000 irrigated acres. Reduce that and then you’re going to reduce groundwater consumption. That helps the water balance so that the aquifer can begin to, and they can meet their sustainability obligation. But we have to say that it’s not limited to Subdistrict 1 or the unconfined if we are reducing groundwater usage throughout the basin. The endgame again is to meet the sustainability obligations and also it makes it easier to comply with a compact if we do that, but reduce the pumping from the aquifers and reduce that groundwater usage.
AC: Does it look to you now that that money, all $60 million, $30 million for each basin will get appropriated at this point? Does it look like the conservation districts have put in place enough of the programs for that money to get spent?
REIN: I believe first of all on the Republican (River Basin) that since they had a structure in place and were already retiring acres in the south, just not at the pace they wanted, that with that structure in place, they are on a good pace to use that funding. For the Rio Grande, they did not have as much of a structure in place and have developed that. But with that development, I believe they have the interest, the applications, I can’t quantify that or go into detail on that, but they certainly will have the interest. And I believe that I would have to really check in with some of the district and subdistrict folks to see what their projection is. But certainly the need is there and the funding is there. So we would hope those come together to see the effective use of all that funding to accomplish the goals.
AC: When you think of the work that’s been done and being done both on the Rio Grande Basin and then Colorado River Basin, what lessons, if any, can be learned from those efforts as we work to bring sustainability to our water resource, our water supply? What are the lessons or what is the work that stands out for you now.
REIN: My role as state engineer, I like to keep my eyes on a few different things just to ensure balance. And we need to look in both the Rio Grande Basin and the Colorado River Basin, first and foremost at the importance of agriculture and how important that is in the Rio Grande Basin. It’s the culture, it’s the economy, it’s a way of life. That’s what sustains that basin. And that’s also true in the Colorado River Basin, but in different ways for the Rio Grande. We just need to balance that attention to the importance of agriculture, to compliance with the law, balance those and balance the importance of agriculture with a compact. And that’s why we have to make these difficult decisions to reduce irrigated acreage because with drought and with demands, the water is just not there. We can’t achieve a water balance. And so that’s how we do that. And I can’t therefore go to the Rio Grande Basin and encourage as much beneficial use as they can possibly accomplish because that would run counter to this effort to comply with the Arps and to achieve sustainability in a slightly different way. I have to deliver a message to the Colorado River Basin that says, yes, our balance is important to the way we regard agriculture and it’s important. And my message to them is, if you have water available and you have a beneficial use and you have the right to water as your water administrator, I’m going to tell you to divert it. I don’t have a basis to tell you to try to conserve, to try to curtail because this is important. I deliver a message of beneficial use on the Colorado River Basin. Now that’s within their water right. And within our system of prior appropriation and in consideration of the fact that in the Colorado River Basin, those tributaries in Colorado and the other three upper basin states, we use less than our allocation under the compact. But there’s no basis to tell people as the state engineer, I want you to conserve. That might be a message from someone else, but not from me. And that’s the message I have to deliver there. But at the same time, we need to be mindful of what other obligations could be put on Colorado in the future. And perhaps you or others who’ve heard me talk about that in the Colorado River Basin right now, we are well in compliance with a compact 75 million acre-feet over every running 10 years. Well in compliance. I spoke to the task force about it just a couple days ago, and we have to be mindful of that number. And if we ever do drop below that number as four upper basin states, the next question is ‘Did we cause it?’ Which really goes to the language of the compact. So it’s very complex and it’s inquiry based. I can’t really project in the near future that we would be out of compliance with a compact. So that’s that different message. But still responsible water usage is the same.
AC: I want to switch to another general topic here, and that’s water for the state of Colorado and the Front Range communities as a whole. In your judgment, have Front Range communities secured enough water for their future or what has to happen for the Front Range to be able to maintain any of its population growth?
REIN: I’m going to give you some quick background as far as our role, and then I’ll be giving you a couple of thoughts on your question. But first of all, it’s good to understand that the role of the Division Water Resources from a statutory standpoint is somewhat limited. And certainly when there’s a development in an unincorporated area, we have a statutory responsibility to provide an opinion to the county, whether the water supply for that developing area is adequate and can be delivered without causing injury. So we do that and that really helps the developments incorporated areas take the steps to ensure that they don’t overextend themselves so that they don’t develop land that has no reliable water supply. When we look at the big municipal and quasi-municipal water providers along the Front Range, it’s a different approach because we don’t have that role or that authority to review their portfolio, review their developments, and ensure that they have enough water. And my observation, even though it’s not a statutory obligation, is that their approach is to develop their water supplies, look closely at their developments, and then they have their role, to things like water and restrictions or other steps. They might take incentives for turf removal, conservation measures, funding conservation measures, or encouraging conservation measures. And that’s how they, and by they I mean greater minds than mine, run municipal water systems. That’s how they keep that balance and ensure that they’re able to provide the water they need to, for their communities in the future.
AC: We’re used to associating you with the enforcement of groundwater rules in the San Luis Valley and Rio Grande Basin. But in reality, that’s just a portion of what the state engineer’s responsible for. Explain the larger role and where the majority of the focus is in the state engineers position.
REIN: The state engineer’s role is just so interesting, and I can’t help but go back about 140 years to 1881 when the position of the state hydraulic engineer was created. And that was created largely to major stream flows so that we could implement these tenets of our prior appropriation system and know the stakes of our 10 newly appointed water commissioners, how to administer water rights that called for the state hydraulic engineer. And over time some of those responsibilities developed to approving bridge design and highway design and reviewing county surveys. But it has both narrowed and expanded in the last 140 years and actually, beginning a hundred or more years ago, to administering these water rights in prior appropriations statewide and supporting our local staff that does that. And of course our dam safety and our water information program. But to answer your question more directly, it is that oversight and support of on-the-ground, bread-and-butter water administration. We have a hundred, 120 water commissioners on the ground that do this work and do it well. What do we need to do to support them? That’s often engineering and technical support. And that comes to a large degree through our involvement in water court, ensuring that we have decrees that are administrable that can be implemented through proper accounting. And then one other facet of that that is very significant, Chris, that I’d like to highlight is what I call or what are known as administrative approvals. And those administrative approvals substitute water supply plans or in the case of the Valley, annual replacement plans, or in the case of the Arkansas, replacement plans. And these are plans that allow water users to use water out of priority, which otherwise would just be disallowed, and recognize their efforts to quantify their impacts to the stream and mitigate those impacts usually through replacement water. This is a significant matter, particularly in the South Platte, the Arkansas and the Rio Grande Basin, and it’s much of what we talked about earlier. It is recognition that groundwater, our formal recognition in 1969, groundwater impacts surface water diversions and we need to account for that in prior appropriation. So since we talked about that in depth before, I will say that much of our staff is actively reviewing the engineering and the administration and the legal aspects of these plans to use groundwater out of priority with replacement to the stream to keep the stream and therefore the other water users whole.
AC: What should the general public know about water as a resource when you think of the years ahead?
REIN: First, I would say that we’re very fortunate in Colorado that we started 150, 160 years ago with a structure in the system called prior appropriation that although it can be very rigid and very harsh, gives us structure and order in what we do so that people have a reasonable ability to project how their water supply may or may not be affected by future conditions and how it might be administered. That structure is so important. I wish there was enough water for everybody, but we developed agricultural and municipal uses in a state that is largely a desert and it often has an abundance for a couple months out of the year. I think it’s good for us to at least feel comfortable that we have that structure in place. But the other thing we need to know, as I alluded to, is that that structure is going to cause us to make difficult decisions, especially as we see climate change, the effects of climate change, reducing our water supply, and we see our demands grow. Those two curves have unfortunately crossed and when they cross, we call it over-appropriation. So we’ve got to implement that. But I think people should also know that Coloradans are smart, they’re creative, they’re solution-oriented. So a lot of these areas where we do see that crossing of those curves, that conflict of the water balance between demand and supply, we’re trying to solve that in ways that address people’s needs. And that may be, or it is so well articulated in our Colorado water plan, but it also is what you see daily on the ground as people maybe seek new initiatives to the general assembly on ways to do things or just creative ways to share water with each other all within the legal structure of our prior appropriation system. Of course. And that’s what I see for the future of Colorado water. We’ve got a difficult balance to achieve, but people are being creative within the system to achieve it.
AC: What is the effect of these drought periods and the warming temperatures that we definitely are feeling in the San Luis Valley and across Colorado?
REIN: Let me be very specific and then work my way out to a more geographically diverse answer to that. But let’s go back to the unconfined aquifer again. Why are we struggling? The fact is that with the prolonged at this point, 20-plus year drought, oh, we’ve had a couple of good years, but the trend is, it’s a 20-year drought that reduced inflows into the unconfined aquifer. There are sources that recharge either through import or through natural inflow. These sources recharge the unconfined aquifer and provide water for the wells to pump, plain and simple. When that inflow is reduced, there’s less water to pump. And that’s also made more difficult by the fact that under these drought conditions, higher temperatures, drier climate, then those crops are going to demand more water. So we get hit twice by that climate impact, and that’s just the unconfined aquifer. If we look at the Rio Grande Basin in general and the reduced snowpack and the San Juans and the Sangres, then we’re going to see less water in the rivers available for diversion. And of course, the compact is somewhat complex in the way that flows are indexed within the state and result in the need to deliver a certain amount to the state line. That’s of course more difficult because of the prolonged drought and the climate change. That’s the impact in the Rio Grande statewide, because we are this headwater state, because we rely so heavily on snowpack that occurs in our central mountains and flows out of the state, then that reduced snowpack is a big part of what’s going to impact us and we’ll get less runoff typically. And that reduced runoff also may occur later, earlier in the season, more likely earlier, and that changes the dynamics. But then the crops are going to demand irrigation at different timing. And again, like I said, for the Rio Grande, the crops have a higher demand if we have a hot or drier climate, so we get hit twice. Again, all in all, it’s that reduced supply generally from snow, excuse me, generally from snowpack that’s going to impact our water users. Now you’ve noticed my focus is really on agriculture because as most Coloradoans know around 85 percent of our diversions go toward agriculture. Now consumption is always a different, more complex matter, but at least 85 percent or so of our diversions go toward agriculture. The municipal supplies are being managed, but that’s where we see the big impact, our lion’s share of diversions.
AC: What is the most worrisome aspect you see when it comes to water as a natural resource?
REIN: I would say that the most worrisome aspect is, again, watching your irrigators. Let me say our irrigators in the Valley. I’ve spent enough time and I seem to know those folks and have a high regard for them. So hopefully they’ll let me say our irrigators in the Valley and the impacts it has on them as they try to deal with this reduced water supply. It’s happening in the Republican River Basin, it’s happening on the South Platte, all of our irrigators in their diversions in the Colorado River Basin. And when I say that, I mean all the tributaries from the YM of the white, the Colorado main stem, the Gunison, the San Juan Animas, La Plata, Dolores, all those areas on the west slope that contribute to the Colorado River. Their irrigation diversions are incredibly important to them. They’re necessary. It’s part of the economy on the west slope. So I spent a lot of time thinking about their need for solutions and strategies and initiatives. That’s an answer to your question of what is worrisome to me. But again, I need to go back to what I said earlier, it’s worrisome but then I also watch creative people with creative solutions. So maybe that takes away some of my worry.
AC: Are there improvements that have to happen so Colorado and the Division of Water Resources get a better at reading snowpack levels with what we’re seeing in the changes of the environment? Because you hear different things about the snowpack itself and is it really as strong as it appears?
REIN: I think that Colorado can benefit from more measurement. I won’t say that Colorado has to get better because Colorado does so many things so well, but I’ll be geographically specific and address the Rio Grande Basin. Due to the nature of the compact and the way Craig Cotton has to administer the compact, I know that he is uniquely interested in good snowpack data because he needs literally to forecast amounts of water so that he knows how much will need to be delivered to the state line on a year-to-year, sorry, maybe I should say on a month-to-month basis. And in order for him to do that, he is actively curtailing water rights again, just to ensure that he comes close to hitting that target and that target is so dynamic based on the types of flows that are occurring. So he has that unique interest in being able to see what’s up in the mountains early on and what could occur as runoff around the state in general, we do have an interest in that. It helps our water users, our municipalities, our producers, forecast what they’re going to see and maybe they can make their own economic decisions too. More data is always good, so I won’t deny that, but I’ll fall short of saying Colorado needs to do better.
AC: Fair enough. Again, we really appreciate all the time you’ve given us. Let me ask you, what’s the advice you leave for your successor when dealing with the Rio Grande Basin and Colorado River issues moving forward?
REIN: My advice for my successor in the Rio Grande and the Colorado River Basin probably applies statewide, but you are right on target that those are two very sensitive areas. And my advice is we really need to give our water users the assurance that the structure I described – prior appropriation, water court decrees – are in place and they’re there for a reason. They’re there for us to abide by them, but we also need to keep one eye on solutions that are based on flexibility, technical innovation that you described, new ways of looking at old problems and being very thoughtful and deliberative about those potential solutions. Can we, under our very rigid system, entertain those solutions? And of course, the answer should be yes, but it requires a character that is willing to say, let me look at that. Let me consider, even though I have concerns right now, let me consider whether there are ways that we can make that work and not injure other water users and not step outside of our very important legal tenants that we have to follow.
AC: What’s next for you?
REIN: Oh boy. I am so looking forward to doing more things with my wife, who, of course, she’s my bride all that time and love in my life, and I have kids and a grandson. And so to have so much of my time opened up to do that is important. Will I step away from water? That would be very hard to do. Do I have a specific plan? No, but I do intend to, either as an observer or something beyond a passive participant, I plan to stay mentally engaged in water.
