Best Time to Visit Nimbus Hatchery

November 16, 2023

Question: Is this the best time of the year to watch salmon spawning at Nimbus Hatchery, east of Sacramento?

Answer: November is the start of a four month stretch when the Nimbus Fish Hatchery is most busy, with Chinook salmon returning up the American River for about two months, and then steelhead trout make that trip in January and February. This hatchery is one of 21 operated by CDFW and it attracts the greatest number of visitors – about 65 thousand people annually in addition to about 10 thousand children on field trips.

CDFW Interpretive Services Supervisor Laura Drath said the hatchery is back to full strength after the pandemic, meaning all tours and public spaces are available. The list of activities includes play areas for children and a preschool story and craft program called Tot Time on Sunday mornings. Visitors can feed fish in the raceways, then walk along the river bluff to see salmon in their natural habitat. Finally, it's also possible to watch as fish filled with eggs make their way up the fish ladder to the processing room where hundreds of thousands of eggs are extracted and then raised on-site until they’re large enough for placement into the river. The Nimbus Hatchery produces about 4.5 million Chinook salmon and 430,000 steelhead trout each year.

This hatchery is widely visited and visitor-friendly because it’s located so close to a populated urban area (about 20 miles east of Sacramento). Drath said this facility is in a great position to represent the important work being done by CDFW.

The Nimbus Fish Hatchery is open to the public every day of the year except Christmas Day (rain or shine).
