USGS Streamflow 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 funds 42 gages, 26 of which are new monitoring stations currently being installed by the USGS. All 26 new gages are expected to be operational by July 2020. Data from these sites are used to support drought assessments, 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.
