SC Surface Water Availability Assessment


    The responsible management of the state's water resources is beyond the scope of any one agency or organization and requires cooperation and shared responsibility amongst all agencies and water users. Stakeholder involvement and feedback is critical to this process. READ MORE >>


    The surface water quantity models being built in South Carolina are intended for long-term agency and stakeholder use to enhance the permitting, planning and management of the state's surface water resources. READ MORE >>


    Did you know that only two of South Carolina's eight major river basins are not shared with other states? This is also the first time that South Carolina will have surface water models developed individually for each basin that can work together for a state assessment. 


    Past information is critical to understand water supply during times of drought, periods of high use and other temporal changes that affect water availability. Past assessments, plans and more will continue to be referenced here. READ MORE >>

Eight major river basins within the State of South Carolina are used for planning and permitting purposes. Of these eight basins, only two are exclusively within South Carolina - the Edisto and Salkehatchie. The Savannah River Basin lies within both South Carolina and Georgia. The Pee Dee, Broad and Catawba Rivers all begin in North Carolina. For these three basins, information on boundary flows at the state line will be obtained from North Carolina.
