RANCHO CORDOVA – As hundreds of Chinook salmon congregated in the rock -lined channel at the entrance to the new Nimbus Fish Hatchery ladder , the Bureau of Reclamation and California Department of Fish and Wildlife ( CDFW ) on November 2 held a short ribbon cutting ceremony marking the completion of the hatchery ’ s new Fish Passage Project . Before the ceremony , hatchery staff took over 700 salmon into the facility in just 20 minutes , according to Gary Novak , hatchery manager . The hatchery trapped a total of 1800 salmon and took over 650,000 green eggs in the two first spawning sessions at the facility after the ladder was open . State and federal officials said the modernized ladder and flume

fishway will help fall Chinook salmon and Central Valley steelhead returning to the hatchery . The 1,900-foot-long passageway consists of a rock-lined channel , weir fish ladder , and concrete flume . The new project features a visitor plaza with underwater public viewing windows . Construction began in spring of 2020 and was completed in October 2021 . Speakers at the event included David Palumbo , Deputy Commissioner , Bureau of Reclamation ; Ernest Conant , Regional Director , Bureau of Reclamation ; Chuck Bonham , Director , California Department of Fish and Wildlife ; and Drew Lessard , Central California Area Office Manager , Bureau of Reclamation . The officials said the project , which took ten years of planning and construction to complete , creates “ a more reliable and safer system ” for collecting adult fall-run Chinook salmon and Central Valley steelhead trout at the Nimbus Hatchery . “ We are very

Bonham . “ We ’ re proud to be part of a project that simultaneously benefits both our hatchery operations and wild-spawned fish and improves the visitor experience along the river and ladder for our Sacramento-area constituents who love to tour this facility , even though it has been closed recently due to COVID-19 .”
Bonham also announced CDFW ’ s Nimbus staff have been tasked with increasing hatchery production to 4.5 million salmon smolts this year by producing 500,000 additional fish to “ combat effects of the drought .” “ Chinook salmon returns to the American River declined significantly during California ’ s last drought ,” said Jason Julienne , supervisor for CDFW ’ s North Central Region fish hatcheries . “ We ’ re using those observations and that experience to get ahead of any population declines this time around by increasing production to help sustain this important salmon run .” However , California Sportfishing Protection Alliance fishery biologist Tom Cannon said in his California Fisheries Blog that “ American River fall-run salmon escapement has dropped after recent drought years and would be expected to fall again in 2022 and 2023 as a consequence of the 2020-2021 drought period .” In a November 2 , 2021 post , the
