South Twin River Basin

The South Twin River Basin is 52 km² (20 sq mi) in the Toiyabe National Forest east of the Toiyabe Range and includes the drainage of the South Fork South Twin River. The river enters the Big Smoky Valley at 1,951 m (6,401 ft) elevation and is completely diverted except during periods of high flow.[1] The adjacent North Twin River Basin is smaller and the North Twin also flows across Nevada State Route 376 to the same irrigation area,[2] and both drainage basins are part of the Northern Big Smoky Watershed.
