WHAT'S AT STAKE?
A river system that drains 5,000 miles of waterways and provides drinking water and recreation for hundreds of thousands of people.
THE THREAT
The impacts of electric power generation and unnecessary reservoir projects.
Comprising 5,000 miles of waterways, the Catawba-Wateree river system originates on the eastern slopes of the Blue Ridge and then winds through the rapidly urbanizing North Carolina Piedmont before entering the lush lowlands of South Carolina. Along its 300-mile route, it provides clean water and recreation for hundreds of thousands of people. Threats endangering the health of this vital resource include:
Pollution from Coal Ash Sites. Coal-fired power plants generate millions of tons of ash, which typically has been dumped into unlined and poorly monitored ponds and landfills. Five of the most hazardous coal ash ponds in the United States are on the Catawba-Wateree River and its tributaries, including a site that has discharged arsenic-laden pollution for years. SELC has filed suit to compel South Carolina Electric and Gas to clean it up.
Water Withdrawals by Power Plants. According to a recent study by the Union of Concerned Scientists, the Catawba River ranks among the 25 watersheds nationwide that suffer from the highest levels of water-supply stress due to the water demands of power plants for steam production and cooling purposes.
Hydroelectric Dams. Over the last century, much of the Catawba-Wateree was impounded to generate electricity, and for decades, power companies have been allowed to operate their dams in ways that disrupt healthy stream flows and fish migration. As Duke Energy applies for a new federal license for a series of five hydroelectric plants in South Carolina, it is seeking to trade land and cash for permission to maintain harmfully low flows in the Catawba-Wateree for the next fifty years.

Unnecessary Reservoir Projects. Two counties—one in North Carolina and another in South Carolina—have proposed a 92-acre reservoir off the main channel of the Catawba-Wateree that is sure to fuel more sprawl and pollution in the Charlotte metro area. What’s more, water withdrawn from the reservoir would be discharged into another river basin, robbing water from downstream farms and communities that depend on the Catawba-Wateree. If approved, this project would pave the way for other municipalities to build their own new reservoirs before first exhausting less environmentally damaging means to satisfy demand, such as increasing their water systems’ efficiency, encouraging their customers to conserve water, and exploring interconnections to other systems with excess capacity. Such reservoirs often needlessly destroy significant wetlands and wildlife habitat.
