The Great Basin is the largest area of contiguous endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than 100 miles (160 km) away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts.

The Walker River is a river in west-central Nevada in the United States, approximately 62 miles (100 km) long. Fed principally by snowmelt from the Sierra Nevada of California, it drains an arid portion of the Great Basin southeast of Reno and flows into the endorheic basin of Walker Lake. The river is an important source of water for irrigation in its course through Nevada; water diversions have reduced its flow such that the level of Walker Lake has fallen 160 feet (49 m) between 1882 and 2010. The river was named for explorer Joseph Reddeford Walker, a mountain man and experienced scout who is known for establishing a segment of the California Trail.
