Chinook salmon have always spawned in Auburn Ravine Creek, a tributary of the Sacramento River in Northern California northeast of Sacramento, but biologists have been uncertain if salmon could get past the Chaparral Cascades.
“As a result, some people have flatly stated that those cascades are a total barrier to upstream migration,” reported Friends of Auburn Ravine in today’s announcement. “They have used that judgement to downplay the potential need to provide a way for salmon to get past the Gold Hill Dam which is about ½ mile further upstream.”
The cascades are about 25 miles upstream from where the creek enters the Sacramento River near Verona. The cascades are steep, and the water runs fast there, according to the group.
“Now there is proof that salmon can get through the cascades to spawn upstream. A local resident noticed salmon spawning about 375 yards upstream from the Chaparral Cascades on November 5, 2016 and preserved video proof of that,” the group said.
