The Trinity River (Karuk: kishakeevrásav) is the longest tributary of the Klamath River, approximately 165 miles (266 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. Designated a National Wild and Scenic River, along most of its course the Trinity flows swiftly through tight canyons and mountain meadows.
The original Hupa name for the Trinity River was "Xun" (Hupa Language Dictionary). It was also known as the Indian Scalp River when first crossed by the Jedediah Smith fur-trapper's party heading northwards up the coast on May 25, 1828.
The river was noted on maps in that year as Smith's River. The name Trinity River was due to an error. When Pierson B. Reading came upon the river in 1845, he named it Trinity after Trinidad Bay, believing that the stream ended there.
The Trinity River flooded massively in the Great Flood of 1862, wiping out the economy of the area.
Jerry García's father drowned in the river.
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 south-southwest 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 west-northwest 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 north-northwest 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.
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 creation of the Central Valley Project in the 1960s and the construction of Trinity Dam and Lewiston Dam diverted most of the water from the upper Trinity to the Sacramento Valley, but a minimum annual release has since been established.
Ecology and Conservation
The river is also known for its runs of salmon and steelhead maintained in part by hatcheries. The king salmon enter the river in mid-July and are there generally through October before fading out in early November. The steelhead arrive in October and typically are in the river through March. 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.
In 1828, the Jedediah Smith expedition was helped across the Trinity River by the Yurok and camped on the east side of the Trinity River. His clerk, Harrison G. Rogers wrote, "Mr. Smith purchases all the beaver furs he can from them", suggesting that beaver were then plentiful on the Trinity.
