A bit of history
The Nimbus Dam was completed in 1955 as part of the Central Valley Project to manage water resources and generate power. The hatchery was established to mitigate the impact of the dam on migratory fish, with operations beginning shortly after. It has since become a vital facility for fish conservation in the Sacramento region.
