Owens River course
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]

On December 6, 2006 the LA Department of Water and Power was ordered to divert 5% of the annual flow of the Owens River out of the aqueduct and back into Owens Gorge to support the trout fishery.
