Almost everywhere in California, salmon are on the decline. But in Putah Creek — a restored stream running through the University of California, Davis, campus — wild salmon are not only increasing, they also are completing their life cycle. A UC Davis study, published in the journal Ecosphere, is the first to document Putah Creek-origin salmon. Chinook salmon have been observed at the creek since 2014, but prior studies had shown them to be strays from hatcheries. This study now confirms that some salmon returning to Putah Creek in the fall to spawn are actually born there.
