Castle, Anne Oral History Interview, Part 2

Speakers

Okay, this is the second half of my interview with Anne Castle for the Glen Canyon Dam Adaptive Management Program on March 26, 2018. So Anne, earlier you were talking about, when you came into the program in 2009, there was a little bit of conflict, policy conflicts or position differences, between the federal agencies involved in the program, and one of your first tasks was to figure out how to resolve those conflicts or differences. And I was struck by your description of the process that you utilized, which was to get everybody to the table, um, and including the tribes, and have everybody talk to each other and begin to slowly and incrementally but successfully work out a way forward that everybody could agree to. And it occurred to me that sometimes this is a little bit different than another type of leadership style, which we’re familiar with in some federal agencies, in which you have a policy determined from the top and an executor, an administrator, make sure that everybody down the line is implementing that unified policy direction. And we assume that that’s the way, that’s how CEOs manage corporations. That’s one style, sort of top-down policy conformance. There’s also this sort of bottom-up collaborative process, which the AMWG [Adaptive Management Work Group] itself is kind of a representative of. I wonder if you could talk a little bit about the differences between those two management styles, why you chose one over the other, and any particular instances where you see the strengths and weaknesses are of those two different kinds of management styles.

I think that part of the reason for the way that I tried to manage the AMWG was the condition in which I found it. And this–the context is important. The Park Service–and when I say the Park Service, that’s not really fair, because it wasn’t the Park Service as the agency, but Grand Canyon National Park, which was the embodiment of the Park Service involved in the AMWG–they had, uh, felt for the entire George W. Bush administration that they were under siege. And they, I think, in some sense envisioned themselves as, um, the rebels that were saving the values of the park. So they felt embattled. I think that was part of the reason that they were so at odds with the other federal agencies, and it was partly because they, the different agencies have different mission descriptions and they, they have to do different things. They’re trying to get to different goals. And so that, that natural tension is going to be there, but in this case it was exacerbated by the politics. And so if I had come in as the Assistant Secretary for Water and Science being identified with the Bureau of Reclamation and told the Park Service how to behave, that would not have worked. That would have been totally counterproductive.

Castle, Anne Profile Photo
Anne Castle 00:03:44

Plus, I’m naturally inclined to value the same things that the Grand Canyon National Park was valuing. So I wanted to find a way that, that all the agencies could work together. And plus, I felt that it was inappropriate and unseemly for the different Interior agencies to be squabbling with each other in public, and I thought that the federal government should make a better showing then that embodied. And so–it was also, the change of administration allowed Grand Canyon National Park to be more accepting of the Obama political appointees than they had been of the George W. Bush political appointees. And so I had an opportunity to make peace. And so we instituted these pre-meetings with the federal agencies. And that was an interesting evolution as well because, the AMWG, let’s say the AMWG meeting would be for two days on a Thursday and Friday. So we’d all come in on Wednesday, and the federal agencies would meet and we’d go through the agenda and figure out what we were, how we were going to vote, and what we were going to say.

Anne Castle 00:05:18

And then, in order to facilitate input from the tribes in a setting that they would feel safer in expressing their opinions, we brought the tribes in as part of that meeting with the federal agencies, because one of the communications issues that was communicated to me was that the tribes felt that their opinions were not heard in the greater AMWG group, and that their positions were dismissed by other AMWG members. And so we thought that it might be helpful to meet with the tribes just as federal agencies, all of whom bear a trust responsibility to the tribes, to see if we could establish better communication and allow the tribes to be more forthright than they might be comfortable being in the larger group. And then, um, the Western Area Power Administration [WAPA], also a member of the AMWG, said, “Well, hey, wait a minute, we’re a federal agency too, and we also have a trust responsibility to the tribes. So why are you just meeting with the Interior agencies?” So, we had this evolutionary process in which we, we started with just the interior agencies, and then we had Interior agencies and then the tribes came in, and then we had just the Interior agencies, then Interior plus WAPA, then Interior, WAPA and the tribes. And we’d all go through this day-long series of meetings, all before the AMWG meeting started, to get our ducks in a row. And some of that was more successful than other parts. I think the–getting the Interior agencies on the same page was the most successful portion of that.

And, these efforts are all being made around particular issues, policy issues. You mentioned endangered species, chub versus trout in the Colorado River.

00:07:27 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:07:40

Right.

What other issues were sort of the flash points for a potential conflict and that required more collaboration and discussion?

00:07:41 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:07:52

Permitting, as I mentioned, permitting of the science.

Castle, Anne Profile Photo
Anne Castle 00:07:57

Um, and there were some conflicts around who was responsible for doing stuff. So, the Park Service has its own science, the Grand Canyon National Park has scientists that do science in the park. And so there were times at which they were concerned that USGS [US Geological Survey], or GCMRC [Grand Canyon Monitoring and Research Center], were usurping their responsibilities or overstepping the bounds, maybe duplicating efforts. That was particularly an issue around cultural resources, because the park has a responsibility to maintain cultural resources within the park. And because of tribal concerns, GCMRC had cultural resource experts, archaeologists, on staff who were also trying to do cultural resource investigation. And so there was a source of conflict there.

And I imagine the tribes wanted to do their own archeology and cultural resource studies too.

00:09:12 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:09:20

In some cases, although that didn’t seem to raise the same conflict as between the federal agencies.

And if I recall correctly, the superintendent in Grand Canyon National Park during some of that period was Steve Martin.

00:09:28 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:09:35

Right.

Were there other Grand Canyon National Park superintendents that were in during that time period that you were involved?

00:09:35 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:09:42

Yeah, Steve Martin’s successor is a guy named Dave Uberuaga who was, who is very focused on ensuring that Grand Canyon National Park had a good working relationship with the other Interior agencies. And in particular with GCMRC. And so he put a lot of effort into understanding what GCMRC wanted to do, needed to do, was being directed to do, what that took in terms of park resources and permitting, and trying to work things out.

So you’ve mentioned the tribes a number of times. One of the issues that has evolved over the life of the adaptive management program has been increasing and making more meaningful tribal input. Many of the people we’ve interviewed have had things to say about that.

00:10:26 Paul Hirt

Is there anything else you’d like to say about the role of tribes, how it may have changed over time, the kinds of issues they’re most concerned about and how you were successful in getting their involvement and input on a more meaningful level?

00:10:47 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:11:05

I think the tribes will always have an important role, and–it is an interesting dichotomy between the tribal cultural values and this highly western scientific effort that’s going on in GCMRC and that the majority of the AMWG members relate to. So, I think the sources of that tension will not go away. In addition to having this pre-meeting with the tribes, I also started having lunch with the tribal representatives and whatever tribal members were coming to the AMWG, because there’d usually be a member and an alternate or a TWG [Technical Work Group] member, sometimes tribal members in the audience. So we get all the tribal members together on one of the two days of the AMWG meeting and just have lunch together, usually without agenda, just to create that relationship and social interaction, which I found very valuable.

Castle, Anne Profile Photo
Anne Castle 00:12:26

And I think that, at the end of the day, the AMWG functions as– a complex set of relationships. And it was, it was incredibly valuable to me to establish relationships with all the AMWG members. And I think that’s particularly important with the tribal representatives, because the, the personal relationship is so important in any sort of transaction or activity with a tribe. And so that was all really valuable. And the tribal representatives tended to be pretty long-lived on the AMWG, and so that provided an opportunity to establish and deepen those relationships. And when you have that, there’s so much more trust and, um, willingness to compromise, and try to be creative about solutions that, I mean maybe you don’t even have to compromise. Maybe there’s a solution that, that gets everybody what they need without compromise. But, I think, if you don’t have a personal relationship, that’s so much harder to do.

That’s a great segue to my next question. I love your statement that the AMWG is fundamentally a complicated set of relationships. Our interview with Mary Orton focused a great deal on her efforts to develop those relationships in a way that allowed the organization to move forward as a, you know, as a kind of a team rather than a whole bunch of individuals fighting for a stake in the outcome. It’s more collaboration, and that was her sort of contribution. Can you mention some of the key individuals that you think have been most consequential in that complicated set of relationships, what role they played and–some people who should be called out and remembered for their work.

00:14:02 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:14:55

Well, I think Mary is a good start. She has had an interesting history with the AMWG, starting as an AMWG member representing American Rivers, and then coming back as a facilitator for a long time, going away for a little while and then coming back again.

Castle, Anne Profile Photo
Anne Castle 00:15:17

So she has institutional knowledge and relationships with a lot of the different generations of AMWG members. And I learned a lot from Mary, um, I learned a lot from her facilitation style and–a component of that was if we were going to vote on a motion, she would type the motion onto her laptop, project it on a screen, and then we’d fiddle with it real-time. And you could do that with suggestions from different AMWG members in a less than fully parliamentary procedure type manner that was much more productive. And we’d end up with something that everybody was looking at as a motion, that pretty much everybody could vote for because they had participated in the process of crafting it. And if they had some concern about this word or that phrase, they could get that corrected before we had to put people on paper, um, with their positions.

Castle, Anne Profile Photo
Anne Castle 00:16:33

And, and so I thought that was a really effective device that Mary used. And another thing I learned from Mary was that she would sort of scan the room and figure out if somebody was looking unhappy but wasn’t saying anything. And she’d make them say something. And we developed a really nice working relationship because, uh–Mary had, for other chairs, I think, taken more of the, I’m going to run this meeting role, um–and, the person who was the Secretary’s [of the Interior] designee was there to make decisions and kind of provide the big picture, but wasn’t necessarily running the meeting. But I ran the meeting, but Mary could facilitate the meeting. And that freed her up to be able to figure out who was mad that wasn’t talking, and tell me, and, you know, we could get that person to express their viewpoint and adjust the process accordingly.

Castle, Anne Profile Photo
Anne Castle 00:17:55

So I felt like we had kind of a good team thing going on, but I think Mary’s style is very inclusive, and–she tries to make sure that people aren’t left behind. And that, that, I think, is key to a functional group where people feel like they’re contributing, that they’re not being ignored, and they’re part of this collective effort. And, you’re right, that’s what we were really trying to create. Okay, we’ve got a problem here. We’ve got a dam that didn’t exist before and it’s upstream of one of the most iconic parks in the world. How are we going to solve that problem collectively? And yes, we have different missions, and different constituencies to respond to. But let’s, let’s work on it. Let’s work on it together. And, so, that was a–

Do you think it was reasonably successful during your time there?

00:19:05 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:19:11

I like to think so and partly because, um, there had been all this conflict and controversy and divided votes and litigation at the beginning, and toward the end of the time I was there–I think all the votes, I remember, were consensus votes without dissension. So we’d come to these decisions collectively. Now, one of the things we did as an experiment, and I’m not sure if it’s still going on, but, this is really, this is another interesting evolution: so, so as I said, when I first started, the federal agencies are spatting with each other and, and voting differently, um–and I said, “We’re not going to do that anymore, we’re going to figure out how we’re all voting, then we’re all voting that way. And the other AMWG members, particularly the states, had been the most vocal about, “What’s going on with these federal agencies? They’re voting in different directions. We don’t know what the Secretary thinks, how are we supposed to figure that out?” And then when we all started voting the same way, they said, “Well, you know, we don’t know what the federal agencies are thinking because you all go in a room together, and you figure out what you’re going to say, and then you do it and we don’t know who’s thinking what.” And so that was, that was, you know, whatever you do, damned if you do, damned if you don’t, I guess. But um, so there was a suggestion that, if the federal agencies were going to all vote the same way, then why should they vote? Why should they be voting members? Which, which is not as weird as it might sound at first, because it’s really unusual to have federal agencies as voting members of a Federal Advisory Committee, which is what the AMWG is.

Castle, Anne Profile Photo
Anne Castle 00:21:14

So it’s a committee that’s set up to advise the Secretary. Presumably, the Secretary can get advice from the Park Service or USGS or whichever, independently. And–so we decided to try as an experiment that the federal agencies would be non-voting members. And that was implemented about midway through my time as the chair of the AMWG. And, as I said, some people liked it, some people didn’t. It gave the federal agencies some freedom though. And we were explicit at the time that–the agencies, the Interior agencies weren’t going to vote, but they were still going to fully participate and they were going to make their views known, so that AMWG members with less time and resources to invest in the program would get the benefit of the expertise and the insight from the federal folks who were, you know, immersed in these issues as part of their jobs.

Castle, Anne Profile Photo
Anne Castle 00:22:35

And so that was a little bit of a struggle. But that was what we were trying to do. So going back to the question of who is influential: So Mary, I would say, but I really think that there were contributions from so many quarters, the Reclamation folks had to think outside of their traditional box, which is water operations. How are we going to manage this dam to get the water where it’s supposed to be and generate electricity? Because that’s what creates revenue. They had to go outside that and think, yes, we have endangered species responsibilities, but we’re all part of Interior and we want to preserve Grand Canyon National Park, and how do we do that, and how do we honor the tribes? And so I think there had to be a considerable evolution in the–the analysis, the sort of internal analysis that the Reclamation folks went through. And that had been occurring over many years since, really, the enactment of the Grand Canyon Protection Act.

Castle, Anne Profile Photo
Anne Castle 00:23:55

But it was happening in real time while I was there and I could see it happening. Ann Gold was the deputy regional director of the Upper Colorado region. And she was the Reclamation AMWG member for many years. And she was terrific in terms of her ability to understand the positions of other AMWG members and try to work with people to figure out a constructive path forward. The folks at GCMRC were very responsive, and under Jack’s [Schmidt] leadership, I think, particularly so, to–not only let’s do science that makes a difference to real people on the ground, but let’s get our results out there. Let’s not make sure that we’ve got thirty peer reviews and, you know, eighty-seven spell checks before we release something. Let’s get it out as soon as we can, understanding and informing people that this may not be final, because it hasn’t gone through peer review, but, but people want to see this stuff.

Castle, Anne Profile Photo
Anne Castle 00:25:20

They don’t want to wait for three years. And so that, that was a huge hurdle for USGS scientists to jump, but they were able to work on that and turn their results around much more quickly than they had before. The Park Service, I think, was also under Dave Uberuaga’s leadership, very accommodating, in ways that they had not always been. And Jan Balsom, who was the chief scientist for Grand Canyon National Park, was really, really helpful in dealing with those tricky cultural resource issues and working with Reclamation to reach an agreement on historic preservation that was part of what had to be done during the time that I was there.

We just arranged to interview Jan Balsom sometime in the next year.

00:26:34 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:26:38

Good.

I’m looking forward to that. Yeah, she’s been involved as a liaison with the tribes for Grand Canyon National Park for decades, so she’ll have great insight.

00:26:39 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:26:50

She does.

During the four or so years that you were involved, were there any really significant events that happened? Sometimes there’ll be a massive flood that changes everything, like in 1983, ’84, or a crash in an endangered species population, or a terrible fire. Was there anything that happened, some event that happened that sticks out in your mind as significant during your tenure?

00:26:54 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:27:21

It was five and a half years that I was there.

Oh, OK… (unintelligible) Thank you.

00:27:25 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:27:30

Probably the most significant things that happened were the high flow releases. And having the protocol in place to be able to do them really quick turnaround was pretty awesome. And so–

Were you doing them annually by that time?

00:27:49 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:27:51

Almost.

That’s a big difference from prior.

00:27:52 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:27:55

Yeah, absolutely. But interestingly, I mean, nature always throws a curve ball, right? And there was one time that they were all ginned up to do a high flow release, and all of a sudden there was a green catfish problem below the dam, and green catfish are apparently even more of a threat to endangered species than trout, like by an order of magnitude.

Castle, Anne Profile Photo
Anne Castle 00:28:25

And there was some concern that doing a high flow release with these green catfish in the system was going to really upend the ecosystem. And they didn’t have much science on the green catfish, and so they didn’t know what would happen. As a result of that, though, the high flow release for that particular year didn’t happen. And so it was, I think that was right after I left, but I knew about it. It was in the works when, when I was still there–it was just a lesson on adaptive management, right? You just, you have no idea what’s going to happen. You can’t predict all these things, and you have to be nimble.

That’s an interesting anecdote. I wonder if they engaged in the same kind of fish control, shocking and killing–

00:29:18 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:29:26

I don’t think so–

That you were suggesting for the trout?

00:29:26 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:29:31

I don’t think they did. I really don’t think they’ve done electroshocking in the upper Canyon since like 2010, something like that. Secretary [Ken] Salazar came to the first high flow release under the protocol. And–I think I went to three of them.

Is it like a party? Does everybody gather at the dam and–

00:29:57 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:30:00

Totally like a party! (Laughter.) Because it’s a good-news story, right? You know, the media is all there and everybody supports, there’s nobody who doesn’t want it to happen. And, well, with minor exceptions. There’s always an exception.

It took a while to get to that consensus, because there was controversy for a long time.

00:30:22 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:30:23

It did. And um, you know, I got to turn the valve to open the bypass, too. Yeah, it’s pretty exciting stuff.

Do you have any pictures of that?

00:30:32 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:30:33

Oh yeah. Oh yeah.

Maybe you can send us a picture of you at the valve (unintelligible).

00:30:35 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:30:40

(Laughing) Okay. I have a wonderful picture that’s one of the ones I treasure from Interior, and I think it’s from the first high flow release under the protocol, and there are six of us who were standing on the little concrete pathway right above the bypass tubes, which is what they open to create the high flow release. So there’s tubes that are a little bit bigger in diameter than this room, um, so, maybe, fifteen feet in diameter? And they are shooting water, you know, maybe–the water is coming out with such velocity that it shoots out maybe twenty, twenty-five feet horizontally before it falls into the river. And so this picture has the Commissioner of Reclamation, Mike Connor, the, our solicitor Bob Snow, who works on all sorts of Colorado River legal issues, the operator from the Bureau of Reclamation, Katrina Grantz, my deputy Lori Caramanian, the Assistant Secr–Deputy Assistant Secretary for Fish, Wildlife and Parks, Jane Lyder, and the bypass tubes are shooting water behind us, and we all signed the picture. It’s great.

I would love to have a copy of that (unintelligible) that would be great. Next question, do you, what do you think, during your term, what do you think you were able to accomplish and what did you want to do that, maybe, you weren’t able to accomplish?

00:32:09 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:32:25

Well, um, I certainly wanted to–uh–correct what I saw was dysfunction in the AMWG when I first arrived. I wanted to–hopefully get rid of the litigation, and ultimately that litigation was resolved by dismissal. (Pause) And I wanted to–resolve the discord among the Interior agencies. And I wanted to involve the tribes in a more meaningful way. And I think we moved toward all of those goals. I didn’t know when I came in that I wanted to have a high flow release protocol, but I figured that out and we got that done and I think that, together with the non-native fish control program, those two things together were significant steps forward in–managing the operations of Glen Canyon Dam in a way that was responsive to environmental concerns, endangered species concerns and tribal concerns.

Castle, Anne Profile Photo
Anne Castle 00:33:53

So I feel good about that. But there’s always more to do. When I left, we were working on the Long-Term Experimental and Management Plan, the LTEMP, and that wasn’t finished until after I left. I was hoping that it would be finished while I was there. The previous long-term plan had been finalized–it had been talked about, um, and I think finalized in the early 2000s. It was time to do another one and to incorporate all the scientific lessons we had learned and incorporate things like the protocol and the non-native fish control program, and to set the stage for the next fifteen years or so of [dam] operations. So I was disappointed that I didn’t get to see that one through, but, but it got done and now is in place. Uh–I think–there are many Federal Advisory Committees that–their goal is to see themselves go out of business, because that advice is no longer required. They’ve given the advice that was requested and now they, you don’t need them anymore. I don’t know that that applies to the AMWG. Partly because our science is always evolving.

Castle, Anne Profile Photo
Anne Castle 00:35:39

And the–the nature of the river is changing, climate change is reducing flows. There will be, at some point, different agreements about the operations of Lake Powell and Glen Canyon Dam to deliver water from the Upper Basin to the Lower Basin that will mean different impacts in the Grand Canyon. And the AMWG needs to advise the Secretary about their interests in those impacts. So I think that– it isn’t and shouldn’t be a goal of this group to put themselves out of business. Um, the nature of the problems will evolve–

Castle, Anne Profile Photo
Anne Castle 00:36:39

The, um, direction that the federal agencies are getting from their political leadership will change over time and they need to hear from the interests that the AMWG represents about how–how their constituencies view the operations of Glen Canyon Dam and how their interests are being affected. So, I think that need will continue to exist. And the fact that they’ve got different problems to deal with now than they did when I first started–that’s great. And different people will be involved, different tribal representatives, different state representatives, and all of that is the mix that was intended when the Grand Canyon Protection Act was enacted in 1992 and said, the Secretary will get advice from these different interests about these operations. That’s what the AMWG is doing. And I think it’s, it’s a really important function, and one that needs to continue.

Yeah, that’s a very compelling argument for the value of the program and why it should continue. Do you think that there is any structural element to the adaptive management program that could be improved? Are there any weaknesses in how the program is, how its representatives are selected, how decisions are made, the connection between science and policies, or anything that you see as a continuing weakness that might be focused on to strengthen the value of the program over time?

00:37:59 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:38:35

One of the things that I had been concerned about when I was at Interior was, the Grand Canyon Protection Act says that the Secretary will seek advice from these different listed interests that include the states and the tribes and recreation and environmental, scientific and academic, and there’s not a designated academic member of the AMWG. And we thought about whether the charter should be changed to include that. There was some thought that the science advisors, through Dave Garrett at the time, served that academic function.

David Braun now.

00:39:28 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:39:28

Okay.

I would think that he kind of served that function, but maybe not.

00:39:28 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:39:34

Yeah. And should that be a different status than all the rest of the AMWG members? Um, I don’t know the answer to that, but it was something that I was a little concerned about. The role of the science advisors was always a little murky to me. And so that was, I guess that was part of why I was concerned because I wasn’t sure, exactly, what the charge of the science advisors was.

Castle, Anne Profile Photo
Anne Castle 00:40:07

So that’s something that I think could be considered if you start changing, especially increasing, the number of people on the AMWG, everybody gets worried that their votes are diluted, and so, it’s a political discussion. It would, it would–have to be thoroughly vetted. So that’s an issue. I remember it being raised when I was there that, um, the state representatives on the AMWG are usually the highest-ranking state water official. It’s been designated by the governor, you know, so Tom Buschatzke [Director, Arizona Department of Water Resources], or the director of the water conservation board in Colorado, or the state engineer in Wyoming. And sometimes they’ll send their designees, their deputies or whoever, but the member is usually the, the state water official. At least that was true, well, most of the time I was there. And then the recreational or, usually the recreational representative might own a bait shop at Page. And so, the concern was expressed that we didn’t have parity among the members. I don’t worry about that. I think that’s okay. Because I think that–you don’t want somebody on the board of American Rivers talking about, you know, going to AMWG meetings and sort of representing the recreational community. You want the guy from the bait shop, who’s right there on the ground, and so that was not a concern that I had. I’m trying to think of anything else structurally.

Castle, Anne Profile Photo
Anne Castle 00:42:18

It was hard, um, having meetings in Phoenix in August (laughter). And those are actually required by the charter.

Oh really? I thought Phoenix was just a good airport hub, but it’s actually in the charter?

00:42:29 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:42:34

Yeah. But we ignored it and had meetings in Flagstaff.

They still do, occasionally.

00:42:41 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:42:41

Yeah. I used to get worried about people just wandering around at 117 degrees.

Are you hopeful about the future of the program?

00:42:53 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:42:58

Absolutely. Yeah. I think it’s a great program. I think–in my experience, the work of the AMWG is listened to in the halls of Interior. I think it serves as an outlet for some of the–controversies that might otherwise erupt in more unproductive ways. I am definitely hopeful about the future. I also think that everybody who serves on the AMWG for any significant period of time establishes relationships with all the other people who are AMWG members and a lot of, the sort of–group that sits around the table, if not at the table, and those relationships are productive in so many ways that we, we can’t even predict. For the environmental representatives to have a personal relationship and go out for margaritas with the head of the state water agency, in the state where their operations are located, that has benefits well beyond the operations of Glen Canyon Dam. And I think it’s really, really important. And just a good incubator for, uh, for good things to happen because of those relationships in water operations throughout the Basin.

You mentioned earlier on the interview, the impact of climate change on water supplies in the Colorado River Basin. I’m sure you already know, Lake Mead is about a third full and Glen Canyon Dam is less than half full and–

60 percent.

60 percent now? And–none of them have been full for a while, and climatologists are not expecting or hydrologists expecting them (unintelligible). So there’s suddenly some discussion now about how long into the future Glen Canyon Dam and Lake Powell are even viable. Do you ever think about that? Does it trouble you? What do you–I mean, this is a long-term program. What’s your thoughts on, on the possible impact on the program and the Colorado River Basin as a whole under current conditions of drought and climate change?

Yeah, well there’s, there’s absolutely no question, but that climate change is affecting flows in the river. And the–the best and most recent scientific evidence is that that effect will be much more drastic in the years to come. 35 percent, maybe, reduction in flows by the next century. Huge numbers. And that, that kind of possible future has to spark pretty intense conversations about how we are going to manage this river differently, if we’re only getting 60, 70 percent of the flows that we’re accustomed to on average. And–that will affect Glen Canyon Dam. As you know, there’s a proposal called Fill Mead First that would put all available water into Lake Mead and only use Powell if there was excess.

You’ve talked to Jack Schmidt, but he’s investigated that most recently. And the idea is of course that, if you only have one big water surface, there’s less evaporation overall, less water loss overall, than if you have two big water surfaces, Lake Powell and Lake Mead. But there are other factors at work and the–Jack’s analysis, which is the most recent, seems to indicate that the projected water savings are not nearly as substantial as might have originally been thought. There was some science done in 2011 that suggested that 300,000 acre-feet a year could be saved if you follow the Fill Mead First protocol. Jack’s analysis suggests that it might be on the order of 50,000 acre-feet.

And in my opinion, that’s not enough to justify the really intense brain damage and Congressional uproar that it would require to do a Fill Mead First protocol. But–this is an area where we don’t have the scientific data we need to reach well-informed conclusions. And we need more information about evaporation from both of the lakes. We need more information about seepage from Lake Powell in particular. We need more information about the potential impact of not having a storage reservoir at Lake Powell on the downstream ecosystems, particularly in the Grand Canyon. I think that if there’s some potential to save 300,000 acre-feet in a river where we’re spending millions of dollars to save 10,000 acre feet, I—that that—if there’s that potential then the scenario needs to be investigated. I don’t think it’s justified by anything we’ve seen currently, but we need to develop the data to be able to do that analysis and reach more definitive conclusions.

Do you think we need another adaptive management program working group authorized by Congress to deal with the larger issues of basin storage and water allocation and climate change? Or do you think the current AMWG could take that on? It’s so much bigger than its original charter, but these are, this is science that needs to be done and collaborative decision making. Who would do that?

The bigger challenge about adjusting to reduce flows is in the first instance a discussion that needs to be had among the states, the seven Basin states, with Interior.

Revisit the Colorado River Compact, you mean, of 1922.

00:50:46 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:50:46

No, I don’t mean that.

Oh, you don’t mean that?

00:50:47 Paul Hirt
Castle, Anne Profile Photo
Anne Castle 00:50:47

No, I’m talking about primarily the interim guidelines. And the interim guidelines were put in place in 2007, designed to be effective through 2026. But they, the Secretary of the Interior is required to start consultation on renewal, or the next iteration, of the guidelines by no later than the end of 2020. That’s not that far away. And so the states need to be involved in those discussions. The drought contingency planning that’s taking place in all of the Basin states, but most intensely in the Lower Basin, is part of that, and will probably, the DCP [Drought Contingency Plan] discussions will probably morph into the re-consultation under the interim guidelines. I think that there’s enough flexibility in the 1922 Compact so that it doesn’t need to be revised, but the operational implementation of the 1922 Compact needs to evolve based on climate change and increased demands. So, but that’s something that the states have to deal with in the first instance. And I can tell you that the states would be very concerned about having an advisory committee with any sort of power around that discussion.

Do you think that the drought contingency plans in place now could potentially have an effect on the ability of the Glen Canyon Dam Adaptive Management Program to continue its high flow event, experimental high flows, continue its research and its work. Is there any potential for water shortages to undermine the continuation of the program, in your opinion?

00:52:28 Paul Hirt

Anne Castle 00:52:57

Oh, I think decisions around the drought contingency plan and how that plays out ultimately can have an effect on operations. I don’t think it’ll affect the high flow experiments, probably not, because the way the dam has to be operated for water delivery is on an annual basis, and so they can jigger around with the timing, and the high flow releases are part of that. So even with diminished releases, they should be able to do high flow releases. Maybe not as high, but even then it’s just a question of how the timing of the releases works during the year. It doesn’t have to affect the annual deliveries. And that’s an important point. That was something people would be concerned, “Well, you’re wasting water, you know, you’re sending Upper Basin water to the Lower Basin and you don’t need to”. And we’d say, “No, they’re getting only the amount of water that they’re entitled to. We’re just re-timing it.”

Anne Castle 00:54:08

So I think there’s no reason why you wouldn’t be able to do that, still. And there’s an energy cost to those high flow releases, because you’re bypassing the turbines, and so you lose the energy production that would have occurred had you released that water in a more uniform way. In the overall scheme of things, that’s a relatively small loss compared to the annual revenue that’s produced by the turbines. But that–because it’s non-carbon energy, that may be a concern in the future, not wasting a drop of water that could be used to produce hydropower. (Pause.) But, you know, that’s a balance. That’s been a balance that the system and the AMWG had to consider from the beginning. So, you know, climate change is having an impact on the Basin as a whole and that’s going to continue and become more dramatic. But, you know, I think that’s another reason why the AMWG needs to continue, so that all those diverse voices understand the impacts of climate change on their particular constituencies and interests, and are able to advise the Secretary.

Great. Last question. What advice would you give incoming member of AMWG? Somebody new coming on the team. What would be your best advice as they launch their participation in the program?

00:55:44 Paul Hirt

Anne Castle 00:56:01

Form relationships with the fellow AMWG members. People have been coming in new for as long as the AMWG has existed. So there are a lot of acronyms, there’s a lot of legend, there’s a lot of institutional history that may feel intimidating to a new member. But pretty much everybody there has been in that position at one time, and I found that people are proud of the AMWG history and are more than willing to help educate new members. But it’s the creation of relationships with your fellow AMWG members that will have the most lasting effect and enable you to represent your constituencies in the most effective way and communicate on a personal level what their concerns are, what their interests are, and be able to work with other members at that personal level to create mutually beneficial solutions.

Thank you so much, Anne, it was a wonderful conversation and I appreciate you taking time to do this.
