Summersville Dam in Nicholas County, West Virginia — The American South (Appalachia)
Running the River
Why Howell-Bunger Valves?
— Summersville Lake —
1) Only a relatively small force is required to move the valve.
2) Excellent flow regulation over a wide range of discharges can easily be obtained.
3) Ability to oxygenate water, benefiting downstream ecosystems.
At the time of installation the Howell-Bunger valves were the largest valves of their type. They are now referred to as “fixed-cone valves.”
Summersville Lake now harnesses the Gauley River thanks to the dam and the Howell-Bunger valves. Completed on March 23, 1966, the outlet structure continues to control the flow of water from the lake. Shortly after they were put into operation, the Howell-Bunger valves suffered fatigue type failure and had to be replaced. The 1966 valve model was replaced with the new, thicker and stronger 1969 valve model. Two new valves were installed in 2012 and 2017.
