Spawning on View Announcement

Artificial spawning on view to public

The public is invited to watch state Department of Fish and Game technicians artificially spawn steelhead from 8 a.m. to noon each Wednesday through March at the Nimbus Hatchery Visitor Center, 2001 Nimbus Road in Rancho Cordova, a hatchery spokesman said.

Each year, workers artificially spawn at least 200 steelhead at the hatchery along the south bank of the American River at Hazel Avenue.

That effort yields about a half-million eggs, according to Terry West, hatchery manager.

With luck, a like number of juvenile steelhead eventually will be raised and released into the river about a year later to start a perilous 125-mile journey to the Pacific Ocean.

After about two years in the ocean, some of those small steelhead reach 7 to 12 pounds and return to the American River to spawn.

Officials estimate that only about 10,000 out of the original half-million make it that far.

The artificial spawning operation is an effort to maintain steelhead runs on the American River.

Construction of Nimbus Dam and Folsom Dam have blocked migration of steelhead and salmon to traditional spawning areas farther upriver.
