Stanislause River Riffles

Completed Projects: Stanislause River Riffles

Stanislaus River - Riffles 47.4, 50.4, 50.9

Background

Three riffles were reconstructed on the Stanislaus River; two near Horseshoe Park and one upstream of Orange Blossom Bridge east of Oakdale, California. The riffle names correspond to the Stanislaus River Mile of their locations. The purpose of the project was to address the need for introduction of quantities of clean spawning gravel into the lower Stanislaus River. The total length of riffle created by the project is estimated to be approximately 675 feet.

Current Status

Construction was completed in 1994.


Monitoring

No physical monitoring plan was created or funded for this project. The Department of Fish and Game planned to monitor salmon escapement throughout the river each fall, documenting total run size and total redd distribution. The number and sizes of redds at the renovated riffle sites were also planned to be monitored to determine project benefits. This project has since been identified by 4-Pumps for monitoring work to be done by DWR. The work will satisfy physical evaluation and maintenance plan design requirements for these sites, and is scheduled for 2005 and 2006.


Reports

Currently, no published reports for this project exist on the Publications section of this website.
