Trinity River

The Trinity River 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 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.

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.[9] 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.[10]

Along this 14.5 mile section (Douglas City Campground to Junction City Campground), fishing and camping are permitted, and no permit is required. 

Gravel bar rapids occur less frequently and deeper cut channels between rocks and high cut banks take their place. Fallen trees pose a challenge. Sone gravel bars allow for camping - check with the Weaverville ranger station for information.
