The Meadow Valley Wash is a southern Nevada stream draining the Meadow Watershed that is bordered on 3 sides by the Great Basin Divide. The wash's Lincoln County headpoint is in the Wilson Creek Range, and the wash includes 2 upper confluences (e.g., the Patterson Wash). Panaca is along the upper wash, and downstream of Caliente is the wash's confluence with its east fork. Just prior to the junction with the Muddy River, the wash flows from Lincoln County into northeastern Clark County.
