• Upper Basin. Special projects, such as the Colorado River Fisheries Project and
the Recovery Implementation Program, have been conducted which involve several
categories.
The earliest work done in the Upper Basin were surveys done by Cope and
Yarrow (1875)., and Jordan (1891, 1896) and Powell (1895). Data collection
pertaining to the native fishes was greatly enhanced when the Flaming Gorge and
Glen Canyon dams were proposed. Potential impacts of the two dams, as well as
a fish control project tied to sport fishing in Flaming Gorge Reservoir, were the
impetus for many studies beginning in the early 1960's. These studies dealt mostly
with life history and project impact analysis (Wydoski and Hamill 1989). Life history
studies included Gaufin et al. (1960), Banks (1964), Vanicek and Kramer (1969),
• and Vanicek et al. (1970). Holden and Stalnaker (1970) investigated Gila
systematics to try and solve identification problems encountered by earlier
investigators (Holden 1968, Smith et al. 1979, Valdez 1980, Smith 1983, Muth and
Platania 1985, Wydoski and Hamill 1989). In the 1970's, McAda (1977), Prewitt
(1977), Seethaler (1978, 1980), Carlson et al. (1979), and McAda and Wydoski
(1980) investigated life history and distribution of the rare fishes. Investigations of
invertebrate populations and their needs were also conducted, including Pearson
(1967), Pearson et al. (1968), Ames (1977), Carlson et al. (1979). In the 1980's,
the Colorado Division of Wildlife and the Utah Division of Wildlife Resources
became involved in life history and distribution studies: Wick et al. (1980, 1982,
1983, 1986), Radant (1982, 1983), Haynes et al. (1982a, b, 1983, 1984, 1985),
