USGS Streamflow and Lake Level Data

The U.S. Geological Survey operates and maintains a network of nearly 200 real-time streamflow and lake-level gages across the State.  SCDES currently supports the operation and maintenance of 65 of these monitoring stations. Data from these sites are used to support drought assessments, flood frequency statistics, flood and emergency response actions, recreational activities, hydrologic modeling, and water planning activities in the State.

This phone number does not provide actual water surface elevations; rather, it provides lake levels relative to the full pond level, which is assumed to be 100.0 feet. For example, if the level of Lake Wylie is given as 97.6 feet, the lake would be 2.4 feet below its level when full.
