Owens River
The Owens River course begins (top left) as Deadman Creek, and the river designation begins where the Big Springs tributary enters the Deadman Creek channel.[1]:89,108,113
Country United States
State California
Length 120 mi (193 km), north-south
Diversion gates that control inflow to the Lower Owens River

The Owens River course includes headwaters points near the Upper San Joaquin Watershed,[2] reservoirs and diversion points (e.g., for the Los Angeles Aqueduct), and the river's mouth at Owens Lake. The river drains the Crowley Lake Watershed (USGS HUC 18090102) of 1,900 sq mi (4,900 km2) and the north portion of the Owens Lake Watershed (USGS HUC 18090103) of 1,340 sq mi (3,500 km2).[2]
