Nimbus Fish Hatchery

Join us this weekend at the Nimbus Fish Hatchery before the Visitor Center closes for the summer! We will spend some time identifying wildflowers and pulling invasive yellow star thistle.
iNaturalist demo and native plant seed packets included! Sign up through the link in the comments.

⚠️The Nimbus Fish Hatchery Visitor Center, raceways (outdoor fish ponds), and parking lot will once again be temporarily closed to the public from May 26 through September 6, 2026.⚠️

During this time, hatchery staff will continue year-round operations to raise Chinook salmon, steelhead, and trout for the American River. The temporary closure allows staff to focus on essential hatchery operations and preparations for the busy fall spawning season.

The closure includes the Visitor Center, parking lot, raceways, tours, public events, and fish feeding activities.

We look forward to welcoming visitors back when the facility reopens on Labor Day, Monday, September 7, 2026.
