The Little Truckee River is a 30.6-mile-long (49.2 km)river that is a tributary to its larger counterpart, the Truckee River, located in Nevada County in eastern California.
The Little Truckee River begins at Webber Lake within the Tahoe National Forest in the Sierra Nevada. The river flows in a general southeastern route to Stampede Reservoir, then Boca Reservoir, and terminates at its confluence with the Truckee River.
The Boca Dam was completed in 1939 during the Truckee Storage Project.
