The North Fork American River is the longest branch of the American River in Northern California. It is 88 miles (142 km) long from its source at the crest of the Sierra Nevada, near Lake Tahoe, to its mouth at Folsom Lake northeast of Sacramento. Prior to the construction of Folsom Dam the river was about 9 miles (14 km) longer making for a total length of 97 miles (156 km). It rises at Mountain Meadow Lake near the 9,008 ft (2,746 m) peak of Granite Chief in the Tahoe National Forest. Flowing initially northwest, the river soon swings west into a gorge, paralleling the Forest Hill Divide on the south. Big Granite Creek then joins the North Fork of the American River coming in from the right. The canyon shallows as the river turns southwest, carving through the Sierra foothills, then turning abruptly south near Colfax. About 4 miles (6.4 km) downstream, it receives Shirttail Creek from the left then is impounded in Lake Clementine (or North Fork Lake) which is formed by the North Fork Dam, built in 1939 to contain hydraulic mining debris.Below the dam, the river bends south, passing under the Foresthill Bridge, the highest bridge in California, then receives the Middle Fork American River, its largest tributary, from the left. The valley widens as the river flows south past Auburn, soon emptying into the north arm of Folsom Lake, a reservoir formed in 1955 by the Folsom Dam. Its waters merge in the lake with those of the South Fork American River and form the American River, a tributary of the Sacramento River.

The Folsom Lake State Recreation Area surrounds Folsom Lake in the foothills of the Sierra Nevada. The majority of it is owned by the U.S. Bureau of Reclamation and is managed by the California Department of Parks and Recreation.

The South Fork American River is a major tributary of the American River in El Dorado County, California, draining a watershed on the western slope of the Sierra Nevada east of Sacramento. The river begins in pristine Desolation Wilderness and flows through the Sierra Nevada foothills. The river at Coloma was the site of James Marshall's discovery of gold at Sutter's Mill on January 24, 1848, which started the California Gold Rush. The South Fork of the American is "the most popular recreation stream in the West" for whitewater rafting in North America, e.g., 80,000 visitors in 2011. Professional whitewater rafting companies have been offering commercial rafting trips on the South Fork American River since 1978.

Folsom Dam is a concrete gravity dam on the American River of Northern California in the United States, about 25 mi (40 km) northeast of Sacramento. The dam is 340 ft (100 m) high and 1,400 ft (430 m) long, flanked by earthen wing dams. It was completed in 1955, and officially opened the following year. Located at the junction of the north and south forks of the American River, the dam was built by the United States Army Corps of Engineers, and was transferred to the United States Bureau of Reclamation upon its completion. The dam and its reservoir, Folsom Lake, are part of the Central Valley Project, a multipurpose project that provides flood control, hydroelectricity, irrigation, and municipal water supply. To increase Sacramento's flood protection to 200-year flood protection (meaning that the area is protected from a flood that has a 0.5% chance of occurring in any given year), the Corps of Engineers recently constructed an auxiliary spillway, which was completed in October 2017; it enables Folsom Dam operators to increase outflows to prevent the lake level from reaching or exceeding the height of the main dam gates.Another Central Valley Project dam, Nimbus Dam, is located further down river.
