<br />000609 <br /> <br />-------- APPENDIX C: FY-2002 - 2003 PROJECT DESCRIPTIONS -------- <br /> <br />the downstream removal effort (#98a) are available and are discussed at the February <br />2002 nonnative fish workshop. If implemented, this upstream effort will: I) reduce <br />numbers of adult northern pike in primary spawning areas; 2) reduce production of young <br />northern pike by reducing numbers of spawning adults; 3) reduce numbers of north em <br />pike moving downstream into critical habitat of endangered fishes by reducing population <br />size in upper Yampa River; and 4) provide angling opportunity by moving northern pike <br />from the Yampa River to isolated ponds that conform to the Nonnative Stocking <br />Procedures and are accessible to Yampa Valley fisherman. Total out year cost: $65,200. <br /> <br />118. Investigation of Nonnative Fish Escapement from Elkhead Reservoir (CD OW, $46,300) <br /> <br />Escapement of non-native fish from Elkhead Reservoir may negatively impact <br />endangered and native fishes in the Yampa River. Screening the reservoir with a flexible, <br />Kevlar-like net suspended in the water column would cost approximately $1 million. The <br />Recovery Program wants to evaluate nonnative fish escapement from Elkhead before <br />investing in such a screen. It is hypothesized that the potential for escapement is greatest <br />during the runoff from May through June. This study will monitor escapement during <br />that period in the 2002-2003 runoff periods. Goals are to document the magnitude and <br />characteristics of escapement of nonnative fishes from Elkhead Reservoir to guide design <br />and operational criteria for potential screening, refine sport fishery management, and <br />evaluate translocation of nonnative fish from Yampa River removal actions. Total <br />out year cost: $50,900. <br /> <br />119. Evaluation of Escapement of Nonnative Warm Water Sportfishes from Starvation <br />Reservoir (UDWR, $70,800) (PLACEHOLDER pending Management Commit lee <br />approval) <br /> <br />Starvation Reservoir is a likely source for escapement of walleye and small mouth bass, <br />highly piscivorous species which pose a predatory threat or competitive to endangered <br />and native fishes in the Duchesne and Green rivers. As with Elkhead Reservoir, the <br />Recovery Program needs to evaluate nonnative fish escapment from Starvation Reservoir <br />before investing in screening. This study is intended to obtain an estimate of the rate of <br />escapement. The project is currently a "placeholder" pending Management Committee <br />approval of higher costs than originally anticipated. Total outyear cost: $64,000. <br /> <br />120. Bottle Hollow Reservoir Nonnative Fish Control Structure (FWS, $38,000) <br /> <br />The Ute Indian Tribe wants to provide a small, I acre fishing pond for Tribal members <br />living in the Tribal Elder Center in Fort Duchesne, Utah. The pond will be located I mile <br />downstream from the outlet of Bottle Hollow Reservoir on the Uintah and Ouray Indian <br />Reservation. The pond will be fitted with a fish screen on the outlet channel to prevent <br />escapement of nonnative fish from Bottle Hollow Reservoir upstream and the pond from <br />migrating downstream into the Uinta and Duchesne rivers. This screening structure will <br />be similar to the modified turbulent fountain structure built at Pariette Draw for the U.S. <br />Bureau of Land Management in 1996, The project will provide recreational opportunities <br /> <br />C-II <br />
