Dry washes are the major watershed feed systems to Imperial Reservoir. The next upstream major watershed feeder is the Bill Williams River from western Arizona. Upstream on the Colorado River, the basic feeder watershed to Imperial Reservoir is the Havasu-Mojave Lakes Watershed of Lake Havasu.
The Senator Wash flows eastward from California into the reservoir.[1] The Wash is blocked by Senator Wash Dam to form the Senator Wash Reservoir, which provides more storage for the canals.[2]
Recreation
The Bureau of Land Management operates camping sites on the north and south shores of Senator Wash and at Xanyō Xamshré (a backwater of the river).[3][4][5] It also operates a long-term campsite below the dam.[6] Hidden Shores, a BLM concessionaire, is located on the east shore of the Imperial Reservoir.[7]
