Although Holden and Stalnaker (1975) mention the White River as part of
their 1967-1973 study of the Upper Colorado River Basin, no records of fish
collections are presented. In 1974-1975, Crosby (1975a,b) conducted a
series of fish collections in the White River within the state of Utah.
This appears to be the first quantitative investigation of this resource.
Prewitt et al. (1978) did a 1977 baseline survey of the aquatic
macroinvertebrates and fishes of the upper White River in Colorado. The
most intensive and well-documented study of the White River in Utah was
conducted by Lanigan and Berry (1979) in 1978 and 1979. A review of this
study is in open literature (Lanigan and Berry 1981). This study reported
the first documented capture of the endangered Colorado, squawfish in the
Utah portion of the White River. Shortly after this study, the Fish and
Wildlife Service (FWS) incorporated the White River into their extensive
investigation of the Upper Colorado River Basin, the Colorado River Fishery
Project (CRFP). A preliminary survey of the White River was done in late
1980, but intensive sampling did not begin until April 1981 (Miller et al.
1982). This CRFP investigation confirmed the presence of threatened and
endangered fishes in the White River through a program of radiotelemetry
with Colorado squawfish. In a cooperative effort with the FWS, Ecosystem
Research Institute (1982) in 1981 conducted joint seining and drift net
sampling of the White River in Colorado and Utah to assess the ecological
requirements and food habits of the riverine fishes. Also, as a cooperative
effort with the ongoing FWS program, Radant et al. (1983) conducted
