TIle ponds constructed in 1990 (and 3- 0.1 acre ponds constructed in 1987) were considered to <br />be temporary facilities. These ponds will be filled when pennanent facilities are available since <br />rehabilitation of water supply and drain lines would cost more than constructing new ponds. <br /> <br />The expenditures by the Recovery Program for construction and research facilities at Ouray through <br />FY 1997 total approximately $6,850,000. The facilities have been used for broodstock development, <br />research, and support of experimental stocking programs. <br /> <br />5.3.2 Horsethief State Wildlife Area/Grand Valley Endangered Fish Facility <br /> <br />HorsethiefState Wildlife Area (SWA) and the Grand Valley Endangered Fish Facility are located on <br />the upper mainstem Colorado River about 10 miles west of Grand Junction, Colorado in the Grand <br />Valley area. Using approximately 20 percent of congressional drought relief funds obtained in 1992, <br />four 0.75 acre and two 0.25 acre refugia ponds were constructed at Horsethief and were operational <br />during the last four months of 1992. The ponds were constructed to hold backup refuge populations <br />of Colorado squawfish, razorback sucker, bonytail chub, and humpback chub from the Black Rocks <br />area ofthe Colorado River. In early 1993, the few remaining tasks associated with pond construction <br />were completed including planting of grass on the pond slopes and installation of a small pump at the <br />outside kettle that served as a truck filling, holding tank, recirculation, and temporary source of water <br />(U.S. Fish and Wildlife Service 1992). <br /> <br />Additional improvements were made to the ponds in 1994 to solve a nitrogen supersaturation <br />problem including the installation of aerators. A saturometer was purchased to monitor nitrogen <br /> <br />26 <br />
