The Trinity River is the longest tributary of the Klamath River, approximately 130 miles (209 km) long, in northwestern California in the United States. It drains an area of the Coast Ranges, including the southern Klamath Mountains, northwest of the Sacramento Valley. Considered especially scenic,[citation needed] along most of its course it flows swiftly through tight canyons and mountain meadows.

Course
It rises in northeastern Trinity County, in the Shasta-Trinity National Forest along the east side of the Scott Mountains, a subrange of the Klamath Mountains. It flows SSW along the west side of the Trinity Mountains into Trinity Lake (20 miles (32 km) long) formed on the river by the Trinity Dam, then immediately into the smaller Lewiston Lake, formed by the Lewiston Dam at Lewiston. From the reservoir it flows generally WNW past Weaverville and along the southern side of the Trinity Alps. It receives the New River from the north at Burnt Ranch and the South Fork Trinity River from the south along the Humboldt-Trinity county line. From the confluence with the South Fork it flows generally NNW through the Hoopa Valley Indian Reservation and joins the Klamath from the south in northern Humboldt County at Weitchpec, approximately 20 miles (32 km) from the Pacific coast. Both Trinity Lake and Lake Lewiston are within Whiskeytown-Shasta-Trinity National Recreation Area.
History
The river has been the scene of placer gold mining, including large-scale hydraulic mining, since the days of the California Gold Rush. The river's swift current make it a popular destination for whitewater rafting and kayaking. The river is also known for its runs of salmon and steelhead maintained in part by hatcheries. The creation of the Central Valley Project in the 1960s and the construction of Trinity Dam and Lewiston Dam diverted most of the Trinity's water to the Sacramento Valley, but a minimum annual flow has since been established. In 1981 the United States Congress designated the entire river downstream from the Lewiston Dam to its mouth on the Klamath, as well as portions of the river's tributaries, as the Trinity Wild and Scenic River. Jerry García's father drowned in the river.
