GOLD RIVER, Calif. – The Bureau of Reclamation will temporarily decrease flows in the lower American River below Nimbus Dam on Friday, Aug. 9, from 2,500 cubic feet per second to as low as 1,000 cfs to prepare the Nimbus Fish Hatchery weir foundation for installation of the weir’s super structure. The weir super 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 will be from 7 a.m. to 4 p.m.; however, Reclamation could begin increasing flows up to 2,750 cfs as early as 1 p.m. If additional work is required, lower flows could extend into Saturday, Aug. 10. Please note that increasing the flows in the lower American River to 2,750 cfs would cause a rise of approximately 1 foot, 4 inches.
Recreationists on or along the lower American River are advised to exercise caution due to cold river temperatures and 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/generic/rel_rep_s.html.
