The upper Sacramento River from Box Canyon Dam downstream to Lake Shasta is one of the premier wild Trout streams in California. Flowing under the shadow of Mt. Shasta, the upper Sacramento River provides easy access, and quality fishing for the angler. Check Sport Fishing Regulations. A swift current and large boulders make wading difficult, although the area is very scenic with good access along most of the reach. Bait & tackle, store, resort, telephone and RV sites with hookups.
