// Strategic Significance
Summersville Dam on the Gauley River is the largest dam in West Virginia and creates Summersville Lake. The dam provides flood control for the Gauley and Kanawha River valleys downstream including Charleston WV. Controlled releases for whitewater rafting make this dam economically significant.
