The Trinity River in Northern California is one of the West Coast's finest wild steelhead and salmon rivers. Below Lewiston Dam, the cold tailwater creates exceptional habitat for rainbow and brown trout, while the lower river hosts impressive fall steelhead runs.
Lower Sacramento River
Redding, Shasta County, California
A world-class tailwater flowing from Shasta Dam, the Lower Sacramento produces consistent dry fly fishing for trophy rainbow trout year-round. Its prolific caddis hatches and remarkable insect diversity create endless opportunities for technical and attractor fishing alike.
