“The dream is to reestablish a natural run of salmon in Putah Creek,” says UC Davis professor emeritus Peter Moyle. In 1972 Putah creek was a trickle of water between heavy machinery mining gravel for the campus roads. Moyle and others urged the university to cease mining and by the end of the decade the machinery was gone and the administration designated a riparian reserve along the creek on campus. After droughts and an ensuing long legal battle, the Solano County Water Agency, which manages the dam upstream, eventually appointed Rich Marovich as Streamkeeper to lead the creek’s restoration. Since then “there’s been an incredible increase in salmon,” Marovich says. Adult counts for recent years have hovered between 500 and 1,000. “That’s in the range where they could be self-sustaining.”
