Environmental and Water Quality Operational Studies. Effects of Flow Alterations on Trout, Angling, and Recreation in the Chattahoochee River between Buford Dam and Peachtree Creek

摘要

This report presents a case-history application of the Physical Habitat Simulation (PHABSIM) system, developed by the US Fish and Wildlife Service. The application was intended to aid in resolving the instream flow needs conflicts among water supply, trout habitat, and recreation which would result from operation of a reregulation dam downstream of Buford Dam, Chattahoochee River, Georgia. This study documents how potential downstream conflicts over project operation to meet fishery, recreational, and other project purposes can be approached, formalized, and resolved from both an institutional and technical standpoint. Results of the study document that multiple downstream uses of the releases from the reregulation dam can be accommodated with relatively minor changes in project operation.
