Section 7. Abstract

Abstract

The ISG's review of science behind the Fish and Wildlife Program has uncovered strong evidence that juvenile salmonids use unsteady and turbulent flow characteristics (e.g., stage waves, turbulent bursts, vortices) as aids in maximizing downstream migration rate and distance per unit of energy expended by a fish. Assuming this to be true (although the weight of biological evidence would be aided by verification studies), reservoir management for optimal unsteady, turbulent flow hydraulics typical of rivers may be more biologically appropriate for aiding migration success than management for flow volume or velocity alone (the main factors considered today). The proposed research is (1) to develop a computer model to test the hypothesis that river flow hydraulics can aid fish migrations; and (2) to develop management strategies for reservoir-river system to provide unsteady and turbulent flow conditions that are more favorable for successful migration. The impact of fish utilization of flow hydraulics is twofold: (1) bioenergetics that salmonids can minimize the energy need for downstream migration; and (2) travel time that determines the length of exposure to various stressors. Without thorough knowledge of the role of flow hydraulics in mainstem passage, the studies on other stress factors such as gas bubble trauma and thermal impact may be misleading. Seeking favorable flow hydraulics through reservoir management may be a more efficient and economical measure to achieve. It may be much less expensive to achieve unsteady and turbulent flow conditions that are favorable to fish migration than drawdown or other measures of water volume control to increase flow velocity and reduce travel time. With two years of research effort, this study would quantify the length of reservoirs in the lower Snake River that would have unsteady and turbulent flows, which are favorable to fish migration behavior, under a range of river flow rates, reservoir elevations, and dam operations. Ultimate outcome of the project will be measured by the usefulness of the results for managing the hydrosystem for multiple purposes, including salmonid populations, as reflected in hydrosystem management plans of Bonneville, the Corps, agencies and tribes.
