• <br />and how to make these recreational fishery programs viable with the need to recover the native <br />species. There has been a good deal of controversy, most of which centers on the use of exotic <br />fishes in the 50-year flood plain of the rivers. There is a great deal of idea, concern and • <br />problem with where and how stocking and management of sport fishes can be programmed to <br />not have unbeneficial effects on the native species. A new wrinkle in this effort is now the <br />proposal to get in the River and remove populations of, for example, Northern Pike from the <br />riverine habitats and place them where they can be utilized recreationally. FWS is now <br />proposing to do this work and evaluate its effectiveness, both in removal from the main stem <br />and with recreation uses over about a 10-year period to see if ideas of this kind will work. <br />The overall monies for the Recovery Program are from Section 7 ESA. Section 7 consultation <br />must go forward utilizing the FWS's interpretation that development in the Upper Basin is <br />ultimately unfavorable for the continued existence of these species and the assumption that <br />activities which fit into the recovery plan are beneficial to the species. This has changed the <br />recovery program to where now everyone is working on the highest and most critical priorities <br />for recovery of the various species in their various ranges rather than focusing on a project-by- <br />project basis of mitigating, and the recovery plan is being addressed rather than particular points <br />of mitigation. The Upper Basin Recovery Plan has so far spent about $30 million. This has , <br />primarily come from the USBR through power generation revenues from the Colorado River <br />Storage Project Act ("CRSP"). The estimated cost needed to implement the program through <br />the Year 2003, which is when the current agreements expire, is about another $75-125 million. <br />During discussion which followed, questions were brought forward about the non-native fish <br />biomass, as being approximately 80 to 90% of non-native minnows and how was the plan • <br />structured to deal with this problem which is several times greater than non-native sport fish? <br />Mr. Hammill replied that the recovery plan is going to show which strategies are most <br />controlling for the non-native minnow species, but that indications to date show that increased <br />flow along the normal hydrograph appear to reduce these fishes. The number of these species <br />are least during years of high flows. In response to questions that efforts to reduce non-native • <br />sport fish would also greatly impact the non-native minnow population as sport fish were <br />extremely predatory upon the minnow populations, Mr. Hammill said that an on-going <br />contracted study with Utah State University may shed more light upon this problem. USU has <br />been contracted to research all the information known about the life histories of all non-native <br />fishes in the system and it is a FWS program to discuss this report with the states and other • <br />interested agencies in an effort to identify and perhaps settle on strategies which could be taken. <br />The report from USU is due in about three months. <br />The group asked Mr. Hammill about the genetic study on the taxonomy of the Gila species in <br />the system which has been in progress several years. Mr. Hammill indicated that he has had • <br />verbal discussions and presentations on some of the information that has come out of the study, <br />but nothing has yet been written and the data is still being analyzed by researchers. The study <br />is a two-pronged effort; first to sample thoroughly the Colorado Basin into Mexico, and <br />determine the populations, their groupings and to sample these populations; second to subject <br />those samples to extensive morphometric, phenotypic and DNA analysis. The study has had <br />8 <br />J
