Nimbus Fish Hatchery is situated on the banks of the American River. The hatchery was constructed to replace the salmon and steelhead runs that were blocked by Nimbus and Folsom dams.
Nimbus is more than just a spawning ground for our finned friends. The hatchery one of the best places to spend time outdoors in the Sacramento region.With its beautiful surrounding scenery, admission to the hatchery is free and interesting,
During the fall, Department of Fish and Game open the gates at the hatchery’s massive fish ladder and begin collecting salmon for spawning.
In a brilliant display of nature, you can watch it all unfold through a huge glass wall in the Visitor Center. On select days, as the salmon flip their fins and lunge from the water as they climb the hatchery’s ladder. At the top, the fish are spawned by hatchery workers and the eggs are collected and fertilized by male fish.
Things to do Nimbus Fish Hatchery
Each year, the Nimbus Hatchery raises around 4.2 million salmon fingerlings that are raised and eventually released back into the Sacramento River-San Joaquin Estuary. Steelhead trout are raised at the hatchery and later released in the Sacramento River near Rio Vista.
Both children and adults are will enjoy viewing the baby salmon, and be sure to bring your nickels to buy fish food from several gumball-like dispensers to feed them. Often times the rangers will also pass out free food.

American River Bike Trail
Another one of the main draws to the site besides the hatchery itself is the pedestrian path that runs along the river that is part of the American River Bike Trail.
This magnificent trail runs approximately 30 miles from Old Sacramento to Lake Folsom and offers hikers, walkers , joggers, and bikers, a safe and serene environment to enjoy their outdoor activities in the company of lively squirrels and birds shaded in a variety of trees, flowers, and foliage.
