Construction <br />of fish passage and screen will begin in FY 2002. Total outyear cost: -$1,600,000. <br /> <br />C-28 HMD/OOOI: Tusher Wash Diversion Dam Screening (BR, $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 />$1,880,000. <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 ofGVIC's decreed water. Total out year <br />cost: 15,000/year operation & maintenance. <br /> <br />" <br />II <br />I: <br />I' <br /> <br />C-29 HMD/OOO 1: Grand Valley Irrigation Company Canal Screening (BR, $1,900,000) <br /> <br />C-6 HMD/9303: Floodplain Restoration (BR/FWS, $1,494,500) <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: 1) 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 habilats 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, 11 miles <br />downslream from the razorback spawning bar. <br /> <br />c-? <br />
