The Summersville Project is located on the Gauley River in Nicholas and Fayette Counties, West Virginia. The project utilizes the U.S. Army Corps of Engineers (USACE) owned Summersville dam which forms Summersville Lake, the largest lake in West Virginia. The dam was built in 1966 in conjunction with two other dams as a means to control flood waters in the nearby rivers. The three dams operate as a system, controlling flow releases into the Ohio River. From its source in the Allegheny Mountains, the Gauley River flows westward approximately 98 miles to Belva, West Virginia, where it turns abruptly toward the south to its junction with the New River at Gauley Bridge, West Virginia. The confluence of the New and Gauley Rivers forms the Kanawha River, which then flows about 97 miles northwesterly to the Ohio River at Point Pleasant, West Virginia. The hydroelectric project was added to the existing dam in 2001.
The project includes a powerhouse, intake structure, penstock, two Francis turbine-generators, a substation, tailrace, and transmission equipment.
The Summersville dam is operated by the USACE which controls the amount and rate of water released through the dam. Operations of the project are coordinated on an hourly basis with USACE. Water is drawn out of the reservoir through an intake structure that leads to a 29-foot-diameter outlet tunnel. The hydro project aerates the water in its controlled release to the Gauley River. A 17-foot-diameter steel penstock conveys water to the powerhouse located downstream of the dam on the right riverbank. The powerhouse contains two Francis turbines with a combined capacity of 80 MW.
The project operates in a run-of-release mode based on USACE releases from the dam. A minimum flow of 100 cfs is discharged from the reservoir at all times. This flow increases based on reservoir filling periods. This flow regime was developed in consultation with West Virginia Department of Environmental Protection and the USACE.
Waters within the project reach are designated High Quality as a National Resource Water. The river in the project area is listed as impaired for pH and mercury. The cause of this impairment is likely due to acid deposition and not due to project operations. The project owner monitors dissolved oxygen (DO) in water releases and enhances DO in discharges to ensure preservation of water quality. DO monitoring reports are submitted to WV Department of Environmental Protection.
Historically, there have been no records of anadromous fish species in the project area. The Gauley River is within the historic range of the catadromous American eel, but passage was blocked in the early 1900s by the construction of several navigation dams on the Mississippi and Ohio Rivers. The West Virginia Department of Natural Resources (WVDNR) has created a diverse fishery in Summersville Lake via stocking efforts. While the population size is small, the fishery supports both warm water and cool water species including largemouth and smallmouth bass, channel catfish, flathead catfish, black crappie, walleye, rainbow trout, bluegill, and yellow perch. The reach downstream of the dam supports a year-round cold-water fishery for trout and walleye, established via WVDNR stocking efforts.
The project lands consist of less than two acres. The only lands owned by the project house the powerhouse, the rest of the area is owned and managed by USACE or WVDNR. The area is characterized by sharp ridges, narrow divides, and V-shaped valleys with nearly vertical cliffs. The streambed is comprised of rapids, cataracts, and large boulders.
Threatened or endangered species potentially present in the project vicinity include the Virginia spiraea, Indiana bat, Virginia big-eared bat, Northern long-eared bat, candy darter, and five species of freshwater mussels. The project owner consulted with US Fish and Wildlife Service to ensure protection of the federally listed Virginia spiraea when installing the transmission line corridor. An avoidance plan was developed which ensured that construction activities would circumvent any populations of the plant species. Project operations do not impact any of the listed species due to USACE control of the surrounding landscape.
The Summersville Dam, built in 1966, is eligible for listing on the National Register of Historic Places. No other cultural or historic resources are found in the project area or surrounding lands owned by USACE. The West Virginia Division of Culture and History (WVDCH) was consulted to assess any impacts on historic resources when the transmission corridor was constructed. The agency confirmed the construction of the corridor would have no impact on any resources. The project owner must consult with WVDCH prior to any land clearing or land disturbing activities to ensure protection of any potential unidentified resources.
Non-project recreational resources at the project include access paths, low water stepping-stone bridges, fish attraction structures, and a boat launch facility in Summersville Lake. A whitewater raft launch is located downstream of the dam, as well as a kayak launch area and handicap fishing platform. Summersville Lake is a popular recreation area and USACE maintains a large campground, marina, three boat ramps, two winter boat launches, picnic shelters, swimming area, hiking trails, and fishing access. Hunting, rock climbing, and scuba diving are also supported. USACE also provides 20 days of whitewater rafting flows in the fall. American Whitewater organizes an annual Gauley Fest – the world’s largest paddling festival – every September, attracting thousands of paddlers from across the country.
There are no facility-specific conditions in the current Certificate.
2022: No material changes or compliance issues were identified. The project remains in compliance based on the annual review. The project reported that WVDEP issued a new NPDES discharge permit for non-contact cooling water which removed the hard temperature limits since Summersville Lake temperatures were often higher than prior permit limits, and instead requires continuous monitoring of water temperature allowing the project to operate within the conditions of the permit
2021: There were no reported changes or compliance issues. The project remains in compliance based on the annual review.
2020: There were no reported changes or compliance issues. The project remains in compliance based on the annual review.
2019: Annual reporting for the current Certificate has not yet taken effect.
January 1, 2022: The LIHI Certificate term has been extended in accordance with Revision 2.05 of the LIHI 2nd Edition Certification Handbook issued January 1, 2022. Refer to the facility table above for the new term.

August 20, 2020: The Low Impact Hydropower Institute (LIHI) has preliminarily approved the Summersville Project (LIHI #17) for a new 5-year term of Low Impact Certification. There are no conditions on the Certificate.
