Fish Monitoring Overview

The Smith River Alliance values the role of science and monitoring in efforts to restore and protect the Smith River. Recent studies have included a long-term population assessment and monitoring program for coho salmon in the Smith watershed, a study of juvenile coho salmon use of beaver and non-beaver altered habitats in the Smith River coastal plain and estuary, an estuary monitoring and Inventory of Juvenile Salmonid Rearing Habitat in the Smith River Plain, and one of the longest running smolt trapping programs in California (1994-2017), located at the Mill Creek Lifecycle Monitoring Station which provides an overall summary of annual Coho Salmon smolt estimates throughout the program’s history.

The Smith River Alliance holds an annual summer fish count to track the abundance of California’s healthiest population of coastal cutthroat trout! We record observations of the rare summer steelhead and spring Chinook salmon, as well as suckers, rainbow trout, lamprey, and herps. Snorkeling within the canyon walls and clear blue waters of the Smith River, volunteers will experience wild fish in their native habitat.
