The American River is a major waterway in California, running for approximately 120 miles from the Sierra Nevada Mountains to the Sacramento River. The river has a rich history, having played an important role in the Gold Rush of the mid-1800s. Today, the American River is a major source of irrigation water for the Sacramento Valley, and serves as a recreational destination for activities such as fishing, boating, and hiking. Several hydroelectric dams and reservoirs have been built along the river, including the Folsom Dam and Reservoir, which helps to regulate water flow in the Sacramento River. The American River is also home to several species of fish, including Chinook salmon and steelhead trout.
