consistent, but sample site and fish capture locations should be considered
close approximations; generally within one mile of the actual site.
This report also provides a brief description of current fisheries
investigations in the White River within the state of Utah. This section is
intended to update WRSOC on current studies near Tracts Ua and Ub.
The final section of this survey is a discussion of the feasibility of
using fishes as an ecosystem environmental monitoring tool. This assessment
considers the completeness and appropriateness of the known fisheries data
discussed earlier and anticipated data collections of current studies. Data
gaps are identified and the need for a fishes monitoring program is
explored. The second part of this discussion section considers the need and
feasibility of a monitoring program for threatened and endangered fishes in
the White River. These needs are discussed in light of the requirements of
Section 7 of the Endangered Species Act for permitting of oil shale
operations.

KNOWN FISHERIES STUDIES OF THE WHITE RIVER, UTAH

Well-documented fisheries investigations of the White River are lacking
prior to 1974. Studies since then have documented species incidence and
composition with the major emphasis on threatened and endangered fishes. A
number of early investigations were conducted in the Green River in and
around the mouth of the White River (Vanicek 1967, Vanicek et al. 1970,
Holden and Stalnaker 1975, McAda 1977, Seethaler 1978) but few sampled
