Current Water-Resources Conditions in Virginia

The U.S. Geological Survey (USGS) and the Virginia Department of Environmental Quality has a network of 261 real-time monitoring stations in Virginia. The network provides real-time water-stage data along with computed streamflow at 188 stations, water quality recorded at 114 stations, ground-water levels recorded at 61 stations, precipitation recorded at 6 stations, and reservoir level recorded at 3 stations. These sites continuously record data on 15-minute intervals and transmit the data via satellite to be incorporated into the USGS National Water Information System database. These data are automatically posted to the USGS NWISWeb site for public dissemination.

Current Daily Streamflow Conditions

Explanation for the dot colors on the surface-water conditions map. The colored dots on this map depict streamflow conditions as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used. The gray circles indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.

Current Ground-Water Conditions

Map of Virginia Climate Response Network
Explanation for the dot colors on the ground-water conditions map. The colored dots on this map depict ground-water conditions as a percentile, which is computed from the period of record for the current month of the year. Only wells with at least 10 years of record are used. The gray circles indicate other wells that were not ranked in percentiles because they have fewer than 10 years of record.
