Springs

The National Park Service, Nye County, U.S. Fish and Wildlife Service, and USGS Nevada Water Science Center (NVWSC) have established a water-level and spring discharge monitoring network in the southern Amargosa Desert to identify long-term trends and monitor potential impacts of activities on groundwater resources. The Amargosa Integrated Monitoring Network (AIMN) continues the long-term...

The Colorado River is one of the longest rivers in the Western United States. It begins in the Rocky Mountains of Colorado and flows southwestward until it reaches Mexico where it becomes a small stream or dry riverbed. The Colorado River forms the border between southeastern Nevada and northwestern Arizona. In Nevada, Hoover Dam and Davis Dam control the flow of the river and create two...

Minimal hydrologic data are available for the Black Rock National Conservation Area (BRNCA). USGS scientists collected baseline spring flow, groundwater level, and precipitation data to support concurrent ecological studies of perennial springs in the BRNCA by the Desert Research Institute. The collection of baseline hydrologic data is the initial step for determining how ecosystems in the BRNCA...

The USGS Nevada Water Science Center, in cooperation with the Bureau of Land Management, is sampling and analyzing water from Grapevine, Kiup, and Rainbow Springs to determine the source of water to these springs. These Springs, located in the Spring Mountains in southern Nevada, provide habitat for endangered spring snail species including the southeast Nevada Pyrg (Pyrgulopsis turbatrix) and the...
