Concrete weirs built in the 1950s in Big Chico Creek are obstructing Chinook salmon and steelhead trout from reaching upstream spawning habitats, according to biologists. The Chico State Ecological Reserve, in collaboration with the Mechoopda Tribe and the City of Chico, is working on the Iron Canyon Fish Corridor Restoration Project, led by California Trout, to address this issue. … The project aims to remove the outdated fish ladder and replace it with a sustainable solution. … This will result in natural resting pools using existing boulders that fish can navigate across varying flows.
