• 13 Utah. Garfield and San Juan Counties. The Colorado River from Brown Betty Rapid in T. 30 S., R. 18 E., section 34 (Salt Lake Meridian) to Imperial Canyon in T. 31 S., R. l7 E., section 28 (Salt Lake Meridian). Bom~tail The bonytail is the rarest native fish in the Colorado River. Formerly reported as widespread and abundant in mainstem rivers (Jordan and Evermann 1896), its populations have been greatly reduced. The fish is presently represented in the wild by a low number of old adult fish in Lake Mohave and perhaps other lower basin reservoirs (USFWS 1990a). The last known riverine azea where bonytail were common was the Green River in Dinosaur National Monument, where Vanicek (1967) and Holden and Stalnaker (1970) collected 91 specimens during 1962 -1966. From 1977 to 1983, no bonytail were collected from the Colorado or Gunnison rivers in Colorado or Utah (Wick et al. 1979, 1981; Valdez et al. 1982b; Miller et al. 1984). However, in 1984, a single bonytail was collected from Black Rocks on the Colorado River (Kaeding et al. 1986). Several suspected bonytail were captured in Catazact Canyon in 1985 - 1987 (Valdez 1990). The bonytail is considered a species that is adapted to mainstem rivers, where it has been • observed in pools and eddies (Vanicek 1967; Minckley 1973). Spawning of bonytail has never been observed in a river, but ripe i sh were collected in Dinosaur National Monument during late June and eazly July suggesting that spawning occurred at water temperatures of about 64 ° F (Vanicek and Kramer 1969). Critical Habitat Critical habitat has been designated within the bonytail's historical range in the following sections of the Upper Basin (59 F.R. 13374). Colorado, Moffat Counri.
