Impact report available for Nimbus Hatchery fish ladder project

The final environmental impact report on the Nimbus Hatchery Fish Passage Project has been released by the federal Bureau of Reclamation and California Department of Fish and Game for public review.

The agencies propose to extend the fish ladder from the hatchery to the Nimbus Dam stilling basin, using the basin itself to hold and divert fish to the ladder.

Under this proposal, the existing weir would be permanently removed and the Department of Fish and Game would recommend changes in local fishing regulations to the California Fish and Game Commission, according to a news release.

The Nimbus Fish Hatchery is along the lower American River, a quarter-mile downstream from Nimbus Dam.

River flows below Nimbus Dam to decrease for work on fish weir

Flows in the American River below Nimbus Dam will be decreased Tuesday and Wednesday for maintenance and installation of a fish weir structure at the Nimbus Fish Hatchery in Rancho Cordova.

The federal Bureau of Reclamation announced that flows will be temporarily decreased from 3,500 cubic feet per second to as low as 1,000 cfs to perform maintenance and prepare the hatchery weir foundation for installation of the weir’s super structure.

Working hours will be from approximately 8 a.m. to 4 p.m. each day. The bureau will increase flows at 4 p.m. Tuesday to 2,500 cfs and at 4 p.m. Wednesday, to 3,500 cfs. If necessary, maintenance flows could extend into Thursday, according to a bureau news release.
