Thesis (M.S.)--Utah State University, 2015.

Low streamflows and warm stream temperatures, caused mainly from agricultural diversions, currently limit available habitat and productivity of trout, including native Lahontan cutthroat trout in Nevada's Walker River Basin. Environmental water purchases, which reallocate water from willing sellers to instream uses, are being evaluated to improve instream habitat. To test the efficacy of existing and potential environmental water transfers, this study uses River Modeling System version 4 (RMS4) to develop a stream temperature model to simulate environmental water transfer effects on stream temperature. Model runs simulate a range of environmental water transfers, from of 0.14 cms to 1.41 cms, at diversions and reservoirs. Results indicate that low flows generally coincide with critically warm stream temperatures, thermal refugia exist on the East Walker River, a tributary of the Walker River, environmental water transfers can improve stream temperature for some highly impacted reaches by up to 3°C in dry years, and environmental water transfers have a greater effect in dry years than wet years.
