The Logan Fishery Experiment Station under Utah Division of Wildlife Resources with a primary function of salmonid broodstock development, disease diagnosis and inspection, fish health investigations, water quality studies, and training. Facilities include lab, office, shop, hatch house, several storage buildings, two residences, 42 new concrete raceways, 14 gravel-lined units, and 10 small units. This is an excellent experimental/research facility. Cool water is available from 15 artesian wells with temperatures too cold for endangered fishes. Either warming facilities would be needed or a deeper well would have to be drilled to tap warmer water. No high risk diseases exist at the Logan FES, but bringing rare fish to the facility could introduce new disease or fish to the hatchery or drai nage. Dri ving time to UCRB rel ease sites is 8-10 hours. 4.1. 5 Ouray NWR This National Wildlife Refuge is located in northeast Utah, 25 miles southwest of Vernal on the Green River. There are currently no hatchery facilities on the site. It occupies 11,500 acres of wildlife habitat, with garage, shop, and two residences. There are eight pumping stations along the Green River and the refuge is laced with a network of roads, dikes, and ditches. This refuge has water rights to 23,000 acre-feet from the Green River, 1890 acre-feet from Pelican Pond, and a 225 gpm well for domestic water. The Green River and Pel ican Pond water is useable for cul ture, but warmer well water would be needed in winter. The water requires filtration to remove sediment, fish, and fish parasites. Aeration is needed to remove H2S and manganese. The refuge is on good impervious alluvial clay, which is desirable for pond construction. This is a good site because of its proximity to the Green River, and to UCRB release sites, as well as to a source of brood stock. The lower Colorado River Basin (LCRB) is 16 hours or about 500 miles away. 4.1.6 Fish Springs NWR This National Wildlife Refuge is located in the Great Salt Lake Desert, Utah, about 140 miles southwest of Salt Lake City, via mostly dirt roads. There are currently no hatchery faci 1 iti es on the si te. The refuge is on 17,000 acres of land managed mainly for waterfowl. Facilities consist of several residences, administration building, garage, and shop. There are water rights to nine springs with a total flow of 40 cfs (28,908 acre- feet/year), and a water temperature of n-830F; good for adult Colorado River fishes. The operation of warm water ponds would require pumping, and the operation of raceways mayor may not, depending on their location rel ative to the water source. The exi sti ng water may be too warm for eggs and fry of the endangered fi shes, necessitati ng a cool water source. The major problem behind this site is its remoteness, the presence of single phase electrical service, a communication system limited to a radio telephone.
