Do You Know the Steelheads' Favorite Stream?

The Southern Steelhead, which once frolicked in the Arroyo Seco, is now an endangered species. There are estimated to be only 300 left waiting in the Pacific Ocean to come back to their homes in the San Gabriel Mountains. The Los Angeles River Fish Passage and Habitat Structures Design (LARFPHSD) project, currently underway, is exploring how to design stream improvements that will provide good habitat and conditions for steelhead trout and other native fish in a 4.8-mile stretch of the LA River near downtown LA, and Arroyo Seco restoration is crucial to the long-term success of that project.
