Lake Roosevelt Water Quality And Hydrodynamic Model Calibration With Fish Bioenergetics, Michael Lee Mckillip

Civil and Environmental Engineering Faculty Publications and Presentations

An understanding of the effects of hydrodynamics and reservoir operations on the Franklin D. Roosevelt Lake (Lake Roosevelt) aquatic food web allows for better management of the reservoir. A CE-QUAL-W2, v.3.5, hydrodynamic and water quality model (Cole and Wells, 20061) is being applied to the reservoir. The models zooplankton algorithms are expanded and a fish bioenergetics model is incorporated. The Lake Roosevelt model extent is shown in Figure 1. The model includes the lacustrine arms up to full pool on the Sanpoil, Kettle, and Colville Rivers; the Spokane River arm up to Little Falls Dam; and the Columbia River from …
