Dry Creek

Background

Dry Creek originates in the lower Sierra Nevada foothills northwest of Folsom Lake and is located within Sacramento and Placer counties. Fall-run chinook salmon and Central Valley steelhead are found in upstream tributaries such as Antelope Creek, Miners Ravine (Cottonwood Dam), and Secret Ravine. There are a number of dams and pipeline crossings that impede the migration of salmonids to upstream spawning habitat.

Project

FPIP worked with the Sacramento Area Flood Control Agency (SAFCA) and others to evaluate different options to address fish passage at Hayer Dam in Rio Linda, the first barrier to upstream migrants on Dry Creek. SAFCA, the owner of the dam, hired an engineering firm to develop modification designs for the dam and a public pedestrian bridge. FPIP staff also participated in initial design review to help refine and further develop an appropriate fish passage option for the diversion dam. In 2004, Hayer Dam was removed, a pump station was installed, and a rock weir fish ladder was constructed to provide anadromous fish passage.
