Dewatering Functional Design Criteria. Surface Bypass and Collection System Dewatering System Field Investigation, USACE Walla Walla District.
Abstract
The U.S. Army Corps of Engineers (USACE) Walla Walla and Portland Districts have developed a program for surface bypass and collection system (SBCS) prototypes for improving survival of juvenile salmon migrating past Corps Lower Snake and Columbia Rivers hydroelectric projects. New surface bypass and collection systems that can safely bypass fish with considerably less spill than that currently used, could be designed to optimize fish passage while at the same time minimizing both dissolved gas related problems and lost power revenues. The purposes of this study were: (1) perform full investigations of the Lower Snake and Columbia River project's existing juvenile fish facilities to determine baseline design, operational and maintenance parameters; (2) identify dewatering systems that may apply to the SBCS; and (3) develop design criteria for dewatering system alternatives.
