The American River is a 30-mile-long (50 km) river in California that runs from the Sierra Nevada mountain range to its confluence with the Sacramento River in downtown Sacramento. Via the Sacramento River, it is part of the San Francisco Bay watershed. This river is fed by the melting snowpack of the Sierra Nevada and its many headwaters and tributaries, including its North, Middle, and South Forks.
The American River is known for the discovery of gold at Sutter's Mill in Coloma in 1848 that started the California Gold Rush and contributed to the initial large-scale settlement of California by white American migrants. Today, the river still has high quality water, and it is the main source of drinking water for Sacramento.
