<br />0M~ <br /> <br />young razorbacks, several adult razorbacks, and several yearling <br />squawfish were harvested during site draining. <br /> <br />Additional sites are being restored during FY 95 and FY 96. The <br />Gravel Pit at 29 5/8 Road (Colorado RM 174), Adobe Creek (Colorado <br />River RM 160), and Walter Walker (Colorado River RM 164) will be <br />used in addition to Old Charlie Wash (Green River RM 250) as <br />controlled facilities to conduct site-specific experimental <br />manipulations. <br /> <br />An inventory of floodplain habitats was conducted for the upper <br />Colorado River basin during FY 93. Irving and Burdick (1995) <br />identified 293 sites consisting of 34,628 acres in 871 river miles <br />of the Green, Colorado, Gunnison, Yampa, and White rivers. <br /> <br />V. Study area <br /> <br />Due to initial emphasis on razorback sucker recovery, the Habitat <br />Restoration Program will focus on areas within the upper Colorado <br />River basin where razorback suckers were historically common to <br />abundant (i.e., Green River (RM 0-398), Colorado River (RM 0-241), <br />and Gunnison River (RM 0-75)). The Yampa and White rivers will be <br />addressed as time and money allow. Following are the geographic <br />areas targeted for restoration, in priority order (although the <br />Program may capitalize on opportunities as they arise, even if they <br />are not in priority order): <br /> <br />1. Green River RM 238 to RM 320 (Pariette to Dinosaur) <br /> <br />-Razorbacks: inhabited by adults, young, and larvae. <br />-Squawfish: includes high density nursery area for young; juvenile <br />concentration area; adult high concentration area. <br />-Approximately 11,222 acres of potential floodplain habitat; man- <br />made levees along much of the river. <br />-Wide alluvial floodplain valley; 60% Federal, 24% private, 12% <br />Tribal, 4% State; includes the towns of Jensen and Ouray, the Ouray <br />National Wildlife Refuge, Stewart Lake Waterfowl Management Area; <br />the White River confluence at RM 246; the Duchesne River confluence <br />at RM 248; Ashley Creek at RM 299, and razorback spawning areas at <br />RM 307 and 311.5. The floodplain within this section is also the <br />most developed along the Green River; mostly cropland and pasture. <br />-flows controlled partially by Flaming Gorge. <br />-willing cooperators include BLM, FWS, possibly the Tribes. <br />-Conclusion: of high biological importance, and highest priority for <br />habitat restoration. <br /> <br />2. Green River RM 0 to RM 238 (Colorado River to Pariette) <br /> <br />-Razorbacks: larvae drift through and use this area; adults reside <br />within the area. <br />-Squawfish: includes high density nursery areas for young; juvenile <br />high concentration areas; and adult concentration areas. <br /> <br />6 <br />
