In-Plant Biological Evaluation of the Red Bluff Research Pumping Plant on theSacramento River in Northern California: 1995 and 1996. A Summary Report, Red Bluff Research Pumping Plant Report Series. Volume 3

摘要

A research pumping plant was constructed on the Sacramento River in northernCalifornia as part of the commitment of the U.S. Bureau of Reclamation to improve fish passage at Red Bluff Diversion Dam; particularly the passage of adult and juvenile chinook salmon (Oncorhynchus tshawytscha). Major portions of construction were completed in May of 1995 with installation on two Archimedes pumps and one internal helical pump. During the remainder of 1995 and in 1996, a variety of engineering modifications were made to pumps, screening facilities and fish bypass systems in the plant. The pumps ran sporadically during this interval. Fish passage work was conducted on an opportunistic schedule. Various procedures were tested for handling fish and evaluating mortality and injury cause by pump passage. Standardized procedures for conducting fish passage studies emerged from this preliminary work. These procedures, to be used for studies in 1997 and 1998, are described in this report.
