The Shasta River flows from the glaciers of Mt. Shasta and from the eastern peaks Klamath Mountains through the pastoral Shasta Valley before entering the rugged Shasta River Canyon on its final descent to join the Klamath River. This seldom-run stretch features Class II+ to III rapids with tight constrictions, overhanging vegetation, and potential wood hazards. The canyon’s stark, desert-like landscape contrasts sharply with the verdant forests just to the west, offering a unique and challenging whitewater experience when flows allow.
After its origin on the Cascades and Klamath Mountains, the two upper branches of the Shasta meet on the floor of the Shasta Valley, bolstered by abundant spring water. Near the middle of the valley, the river is impounded by Dwinnell Dam, which diverts flow for alfalfa and hay production near Montague. Downstream of the dam, the Shasta meanders across the valley floor and is joined by the Little Shasta River. A few miles north of Yreka, the Shasta flows beneath the Interstate-5 bridges and plunges headlong into the short but rugged Shasta River Canyon, transforming into a whitewater river on its final plunge to join the much larger Klamath River.
The Shasta River would be boatable year-round, flowing with abundant base flows provided by several large springs in the valley above but agricultural diversions have taken nearly all of this springwater from the river for much of the year, affecting the health of the river, its salmon fishery, and leaving little water to flow down the final canyon and into the Klamath. Boaters will need to check flows and count on short windows of opportunity in the late fall through winter to catch a decent flow for this run. Due to agricultural runoff, expect poor water quality.
Unlike Mt. Shasta, the river is small and somewhat diminutive, especially considering the size of its watershed and the abundance of its volcanic springs. Rapids are generally class II+ but tight constrictions, dense overhanging vegetation, and its shallow nature elevate its difficulty to III, wood hazards notwithstanding. It is possible to get down the river at flows as low as 150 cfs but 300 cfs or higher is more friendly to gear and is more enjoyable. Unfortuantely, when flows are high enough for boating--which is uncommon in many years--the water quality is usually (but not always) poor and full of agricultural runoff and overflow from Yreka's sewage treatment plant.
All of this may sound like a deterrent, but it's the reality of a unique whitewater river that has been greatly impacted by upstream land use and water mismanagement. On to it's more endearing characteristics. From its source to its confluence with the Klamath, the Shasta's water drops 12,000 vertical feet, making it one of the steeper river systems of the West. It's canyon may be marred by road cuts and bridges, but is also spectacular and interesting, and seemingly out of place in northwest California. It looks more like a desert canyon you'd expect in Arizona or Southern California than in the Klamath watershed, a river system that flows into the ocean in a temperate redwood rainforest not that far away. The Shasta River has been found to be eligible as a federal Wild and Scenic River with whitewater recreation as one of its outstandingly remarkable values. The Shasta is critically important for the survival of Chinook salmon as a species in the Klamath watershed and holds great cultural significance to several Tribes. So, despite its challenges and abuse, it is worth exploring, restoring, and protecting.
Logistics
State Highway 263 runs the length of the Shasta River canyon, usually high above river level. It crosses the river several times on historic arch bridges.
*Put-in*
Put-in access is challenging, with all the riverside land under private ownership. Fortunately, in California, the public is afforded full legal access to rivers within the right-of-way of any county or state road--meaning you can get in and out of the river at bridges on these roads so long as you stay within the right-of-way, typically 30 feet each side of the road or bridge.
That's they key for putting in the Shasta River, and there are two options: at the Highway 263 bridge that's about four miles north of Yreka or at the Anderson Grade Road bridge, about one mile upriver. Park legally on the road shoulder or at a pullout and stay within 30 feet of the bridge to access the river. Boaters are an uncommon sight, so don't be surprised if you attract some attention.
*Take-out*
Take out on river left upstream of the lowermost Highway 263 bridge over the river. Access to the river here is provided via Hudson Road, which leaves from the west side of Highway 263 and curves around beneath the bridge, passes through a unique little neighborhood, then continues away from the homes to head upriver. The appealing looking river access right by the bridge is on private property and within sight of the neighborhood. There are other spots you can get out of the river if you continue upstream, but to get on to public BLM-managed land you'll need to go 0.4 miles upriver from the bridge.
It is possible to continue on the Shasta to the Klamath and take out downstream on the Klamath along Highway 96. This is complicated by an in-stream hazard on the Shasta about 3/4 mile below the Hudson Road take-out. Here, a California Department of Fish and Wildife fish counting weir spans the entire river and poses an obstacle to boaters. The weir is sharp, fence-like, and completely unpassable.
