Selected hydrologic data for the Powell River basin in Wise County, Virginia

Evaluation of selected surface-water, ground-water, and water-quality data shows that hydrologic data collected by governmental agencies comprises less than 10 percent of the total data available in the Powell River basin, Virginia. Only a small portion of the hydrologic data for the basin has been compiled and stored by Federal and state agencies in two computerized hydrologic indexing systems (National Water Data Exchange and Commonwealth Data Base). Selected ground-water, surface-water, and water-quality data collected in the Powell River Basin in Wise County, Virginia are summarized. The data are obtained from three coal-mining companies, the Virginia State Water Control Board, and the U.S. Geological Survey. Water-quality data for 61 ground-water and 86 surface-water sites indicate elevated iron and manganese concentrations are present throughout the basin. A bibliography of available hydrologic reports on the area and selected pertinent hydrologic reports from other coal-producing areas is present. (USGS)
