River flow
South Carolina river-gauge histories
Explore daily flow readings and history at 114 named USGS gauges in South Carolina. These are individual monitoring sites, not a complete inventory or a river-wide water-health score. Check the gauge location, date and source notes. Flow does not establish drinking-water safety or supply to a home.

Reported water use
Where reported water use comes from
These totals, in million gallons, come from South Carolina DES Table 2. They cover registered and permitted users, so some water use is not included.

Hydroelectric reported use dominates totals and represents water passing through generation, not consumptive use or environmental danger. Registered and permitted withdrawals; surface-water regulation applies above 3 million gallons in any month. Source: PDF page 24, printed page 11, Table 2.

Water planning in South Carolina
State planning records and permits describe supply and management decisions. They are separate from measurements of current conditions.

These reports cover withdrawals above the legal reporting threshold, so smaller uses may be missing. A groundwater management boundary does not tell us the current condition of the aquifer.
- South Carolina Department of Natural Resources: 2025 South Carolina Water PlanDeterministic document references are preserved; plan content is not a current observation.
- South Carolina Department of Environmental Services: Surface Water WithdrawalsAuthorized, registered, and reported withdrawal semantics remain distinct; withdrawal is not consumption.
- South Carolina Department of Environmental Services: Groundwater Capacity Use AreasA capacity-use designation is a management jurisdiction, not proof of a current groundwater emergency.
- South Carolina Department of Natural Resources: Simplified Water Allocation ModelsModel outputs are planning tools, not observations.
