and do not attempt to quantify different river habitat types (Munn and Brusven 1991,
Grzybkowska 1989, Grzybkowska et al. 1990). Others have been directed towards
specific river habitats such as riffles (Morgan et al. 1991, Rader and Ward 1988),
floodplains (Gladden and Smock 1990), and tailwaters of reservoirs (Swink and Novotny
1985). Relatively few have been directed towards multiple habitat types in a single river
system (Grabowski and Hiebert 1989, Beckett et al. 1983).
In our study, we investigated the fluctuation of benthic invertebrates, from June
through August 1991, in the Green River at the Ouray National Wildlife Refuge, Uinta
County, Utah, U.S.A. (Fig. 1) We examined sites representing four habitat types as
follows: River channel, ephemeral side channel, river backwater, and seasonally
inundated wetland. Our purpose was to determine densities and assemblages of the major
benthic macroinvertebrates in these four habitats associated with the Green River.
