About the Sacramento

The Sacramento River starts below Lake Siskiyou at Box Canyon Dam and runs south through Dunsmuir and Castella toward Shasta Lake. The upper river is a wild trout stream that fishes like a freestone. It drops fast, with pocket water and pools. Interstate 5 follows much of it.

Fly anglers commonly use I-5 off-ramps at Soda Creek, Castella and Sweetbrier. Box Canyon at the top is narrow and reached from Ney Springs. The area near Dunsmuir has a stocked section in some years.

The river holds rainbow trout, steelhead, smallmouth bass, largemouth bass, striped bass and carp. Rainbows are the main target on the upper river. The lower river near Redding offers steelhead, smallmouth and carp. Caldwell Park and the Colusa Sacramento River State Recreation Area are named spots farther down.

Summer and fall are popular. Fall caddis are the known hatch. Midges and Parachute Adams are common patterns.

Seasons and gear rules differ by reach. Check current California Department of Fish and Wildlife regulations before you go.
