Lake Lynn

IMPORTANT NOTICE: On Wednesday December, 1 an equipment malfunction at the Lake Lynn powerhouse resulted in a 10- to 15-gallon hydraulic oil release into the tailwaters. Containment and clean-up activities began immediately upon discovery of the incident and our emergency environmental response contractor was called to support the effort. Both the Pennsylvania Department of Environmental Protection and the West Virginia Department of Environmental Protection were immediately notified. Information was also shared with the National Response Center [NRC]. All oil released has been contained; however, clean-up activities are expected to continue into the week of December 6.

Lake Lynn Generation highly values and respects the pristine environment in which we have the privilege of operating our renewable energy producing hydro facility. We work diligently to prevent incidents such as this and regret having this occurrence.

Protecting the environment is one of our top values and priorities, along with employee safety and public safety. We will continue to work diligently to protect our employees and the public from injury and prevent incidents from impacting our surrounding environment.

Fact Sheet

Located in northeastern Monongalia County, W.Va., Cheat Lake was formed in 1925 by damming the Cheat River to serve the needs of a hydroelectric generating facility, the 52-megawatt Lake Lynn Power Station, now owned and operated by Lake Lynn Generation, LLC.

The area was documented for development by a young George Washington, who envisioned a canal and portage system involving the Cheat River and the Lake Lynn area. Actual planning and development of the hydro plant began in 1910, but was stalled around the time of World War I. Construction was resumed in 1925, and the first water flowed over the 125-foot dam on Dec. 23, 1925.

At a ceremony in 1927, a bronze tablet, embedded in a great rock near the power station, dedicates the lake and the generating facility to the public “In lasting beauty for recreation and the supplying of essential service.” The 13-mile lake has been a popular recreation spot ever since.

In June 2000, Allegheny Energy added a 20-acre park and 4.5-mile hiking and biking trail on the banks of Cheat Lake for the enjoyment of the general public.
