Beaver Dam Wash

The Beaver Dam Wash is a seasonal stream near the southwestern Utah-Nevada border. At its southern end in northern Arizona, near the point where it empties into the Virgin River, the stream flows throughout the year. Part of the wash is in the Beaver Dam Wash National Conservation Area, managed by the Bureau of Land Management. The wash was so named on account of beaver dams which once were built on its course.

The wash occupies a transition zone among the Colorado Plateau, the Great Basin, and the Mojave Desert ecosystems. Like all such zones, this area supports diverse vegetative communities and a rich array of wildlife. The wash begins in the Clover Mountains in Lincoln County, Nevada and flows south across very sparsely populated desert terrain. The area around the wash, including a number of protected wilderness areas, includes forests of Joshua trees along with other yuccas, cholla cactus, barrel cactus, Mormon Tea, and other grasses and shrubs are the primary vegetation in the area.

Animal life in the area consists of a variety of lizards, mammals, birds, and insects, and other creatures found in the Mojave Desert. The lower elevations provide designated critical habitat for the threatened desert tortoise and other native species, such as desert bighorn sheep, gila monster, and mojave rattlesnake.
