DroughtWatch: Surface Water Conditions in Tennessee

The U.S. Geological Survey (USGS) has a network of surface-water real-time monitoring stations in Tennessee. The network provides real-time water-stage data along with computed streamflow at many of these locations, and rainfall recorded at some stations. These sites continuously record data on 15-minute intervals and transmit the data via satellite to be incorporated into the USGS National...
