For Release: August 04, 2014

GOLD RIVER, Calif. – The Bureau of Reclamation will temporarily decrease flows in the lower American River below Nimbus Dam on Friday, Aug. 8, from 1,500 cubic feet per second to as low as 800 cfs to prepare the Nimbus Fish Hatchery weir foundation for picket installation.

The fish weir structure is installed annually to guide spawning Chinook salmon into the hatchery fish ladder. Folsom Dam, Folsom Reservoir and Nimbus Dam are located about 25 miles east of Sacramento, Calif., and are features of the Central Valley Project.

Approximate working hours on Aug. 8 will be from 7 a.m. to 4 p.m. Following completion of the work, Reclamation will begin increasing flows back up to 1,500 cfs. This could happen as early as 1 p.m.; however, if additional work is required, lower flows could extend into Saturday, Aug. 9.

Please note that increasing the flows in the lower American River back up to 1,500 cfs would cause a rise of approximately 8 inches near Nimbus Dam. Recreationists on or along the lower American River are advised to exercise caution due to variable flow conditions.

Daily information on expected flows in the American River can be found on the California Data Exchange Center website at http://cdec.water.ca.gov/queryRes.html or on the U.S. Army Corps of Engineers website at http://www.spk-wc.usace.army.mil/reports/release_changes.html.
