Construction <br />offish passage and screen will begin in FY 2002. Total out year cost: -$],600,000. <br /> <br />C-28 HMD/OOO]: Tusher Wash Diversion Dam Screening (SR, $300,000) <br /> <br />The Tusher Wash Diversion Dam canal intake on the Green River can (and has) entrained <br />native and endangered fishes. Hydroelectric power production has been discontinued due <br />to a legal dispute. Once this dispute is resolved and a design flow rate determined for the <br />fish screen, alternatives for screening can be evaluated and pursued. Total out year cost: <br />$] ,880,000. <br /> <br />C-29 HMD/OOO] : Grand Valley Irrigation Company Canal Screening (BR, $] ,900,000) <br /> <br />The Grand Valley Irrigation Company canal intake also has the potential to entrain native <br />and endangered fishes. In FY 2002, a screen will be constructed to exclude adult fishes <br />while allowing unimpeded diversion ofGVle's decreed water. Totaloutyear <br />cost: ]5,000/year operation & maintenance. <br /> <br />C-6 HMD/93 03 : F]oodp]ain Restoration (BR/FWS, $] ,494,500) <br /> <br />Restoration and enhancement of floodplain functions to assist in recovery of endangered <br />fishes within the upper Colorado River basin. The objectives of the floodplain restoration <br />program are: I) determine the amount of nursery habitat needed to recover razorback <br />sucker and bonytail; 2) restore/enhance nursery habitats to entrain and sustain larvae; and <br />3) protect the best remaining adult and juvenile floodplain habitats for seasonal use by <br />endangered fishes. FY 2002 activities include: <br /> <br />_ Determine effectiveness of Bonanza Bridge and Above Brennan sites on the Green <br />River at entraining drifting larvae. (C-6 larval entrainment study) <br /> <br />_ Stock razorback and bonytaillarvae into Green River floodplain wetland depressions to <br />determine levels of survival in the presence of nonnative fishes. (C-6 rz and C-6 bt) <br /> <br />_ Survey Bonanza Bridge and Above Brennan sites on the Green River post-runoff to <br />determine physical response to upstream levee breaching. <br /> <br />_ If easement is acquired, breach wetland levees at Thunder Ranch (formerly known as <br />Escalante Ranch) to entrain drifting larvae. <br /> <br />_ Develop management plan to allow selenium remediation while benefitting razorback <br />suckers and waterfowl at the Stewart Lake Waterfowl Management Area, ]] miles <br />downstream from the razorback spawning bar. <br /> <br />C-? <br />
