<br /> <br />THE <br />BALANCING <br />ACT <br /> <br />recovery of the endangered fishes for about 20 years. I <br />can tell you from experience that we would not be <br />doing many of the recovery actions we're doing today <br />and not be seeing the glimmers of hope that we're <br />seeing today without the broad support and the <br />substantial funding the program receives. <br />Because of that support, the program has a strong <br />and comprehensive package of actions that, when <br />accomplished and when completed, recovery of these <br />fishes is expected to occur. These actions are based <br />upon the best scientific information we have today. <br />They include such things as water management to <br />provide flows for the fishes and their habitats; habitat <br />enhancement for restoration; and control of non- <br />native fishes that may compete with or prey on the <br />endangered fishes. We also have a propagation <br />stocking component whereby we would stock fish to <br />augment populations or even re-establish populations <br />in the case of the bony tail. <br />I believe we made solid progress in all of these <br />areas during the course of the recovery program but <br />especially within the <br />last five years. I think <br />Another major we've seen the <br /> <br />work with the non- <br /> <br />greatest improve- <br />ments and greatest <br />strides occurring in <br />the last five years. <br />I believe the water <br />users view the <br /> <br />challenge throughout <br />the basin is how to <br /> <br />SYMPOSIUM <br />PROCEEDINGS <br />SEPTEMBER 1999 <br /> <br />o <br /> <br />program as a success. <br />The program serves <br />as the RPA under the <br />Section 7 agreement <br />and non-jeopardy <br />opinions have been <br />issued on about 500 <br />projects depleting about 600,000 acre-feet of water <br />since 1988. So thete is a human factor in the <br />program. <br />What about the fish and their recovery, will it ever <br />be achieved? I think the answer to that question is, it's <br />too soon to tell. I mentioned that we've made strong <br />progress in implementing a wide variety of recovery <br />actions and there are signs that the fish are respond- <br />ing in a positive way to these recovery actions. One <br />thing about these fish is that they are long-lived fish <br />so their responses to our recovery actions are often <br />slow in showing up. <br />Some examples of those positive signs. Colorado <br />pikeminnow populations in both the Green and <br />Colorado rivers are increasing. Since the program was <br />established, there's been about a three-fold increase in <br />the catch rates of adult pikeminnow in the Green <br />River and about an eight-fold increase in catch rates <br /> <br />native fishes in our <br /> <br /> <br />recovery efforts. <br /> <br />- Bill Rinne <br /> <br />of adult pikeminnow in the Colorado River. Hump- <br />back chub populations in the Colorado River in <br />Black Rocks and Westwater Canyon are stable or even <br />increasing. Some of our most recent population <br />estimates would indicate we have strong populations <br />there and there's recruitment to the populations <br />occurring. Razorback sucker. For the first time since <br />perhaps the 1960s, we're seeing recruitment in <br />razorback sucker populations in the Green River. <br />We're also recapturing fish we have stocked on the <br />spawning bar, so there's indications that these stocked <br />fish are recruiting back to the adult reproductive <br />stock. The bony tail. Wild bonytails are virtually <br />extirpated in the system so we'll have to restock those <br />fish back into the wild to re-establish populations. <br />We have recaptured these stocked fish and all <br />indications are that they are growing well and they're <br />surviving well. <br />So, there are positive signs that the program is <br />working for the fish. We have a ways to go, but the <br />road ahead of us does not appear quite as bumpy as it <br />did at one time. I think there's light at the end of that <br />recovery tunnel for the Upper Basin fishes. <br /> <br />RINNE: I have a couple of points. I'll just focus on <br />major problems yet to be addressed and the fishery. <br />There are about four things I've listed here. I'll just <br />touch on them and then maybe some of the others <br />will want to expand on them. <br />One of the major challenges in front of us is how <br />we want to approach recovery in the future in terms <br />of integrating a lot of these very good but, very <br />separate programs in the basin into an ecosystem <br />approach. Another major challenge throughout the <br />basin is how to work with the non-native fishes in <br />our recovery efforts. My view is that the well inten- <br />tioned hopes of getting rid of non-native fishes are <br />dreams. The fishery in the Colorado today is a <br />Mississippi drainage fishery that's been moved in. It's <br />here with us and we need to work with it. So I think <br />the major challenge is: How do you work with that? <br />A second challenge is trying to reach an agreement <br />on the scope of recovery that's really acceptable. This <br />gets back to this notion of balancing the environ- <br />ment. In other words, do you do it in zones and focus <br />on something like Bob said where you have areas <br />where you have natural recruitment occurring, or do <br />you try to re-establish this throughout the basin, the <br />lower river and the Delta? <br />Finally - to see if I can get some response from the <br />panel- would be this idea: Where we identify or <br />expect that water is to be dedicated for fishery needs, <br />whether it be in the Delta or on the mainstream, how <br />are we going to get that water? How will it be <br />dedicated? Who is going to provide it? These are <br />
