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
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.
