Pieces of the Feather River Fish Hatchery have been patched back together in time for the return of spring-run chinook salmon. However, the shoveling, shifting and trucking will continue for a while until its smooth swimming for the important fish-rearing station on Table Mountain Boulevard. This week, staff has begun to trap spring-run fish that will be tagged before being released back to the river. “They’re coming in really slow,” said Penny Crawshaw, a fish hatchery manager. High volume releases of water from the dam continued until recently, which encouraged fish to hold lower in the river, she explained.
