Coho salmon have naturally reproduced in the upper Russian River basin, traveling over 90 miles upstream for the first time in more than 30 years. The sighting of juvenile salmon in Ackerman Creek near Ukiah is promising, attributed to habitat improvements, favorable ocean conditions, and recent wet years. Despite declines since the 1940s, current effortssuggest a significant potential for a major comeback, with coho salmon reported to have been seen on the Noyo, Big and Navarro rivers in Mendocino County.
