The U.S. Army Corps of Engineers (USACE), Baltimore District is investigating a revised plan of operation for the water supply storage owned by the Susquehanna River Basin Commission (SRBC) at Curwensville Lake, Pennsylvania. Curwensville Lake is a dammed section of the West Branch Susquehanna River. The dam lies about 2 miles south of Curwensville Borough.  At the request of SRBC, USACE is examining ways to more effectively use SRBC-owned water storage at the lake through modifications to the current water release operations plan. Modified releases could help offset downstream consumptive water use during dry years and support stream ecosystem flow needs as determined by The Nature Conservancy.

Downstream water bodies potentially affected include the West Branch Susquehanna River and the Susquehanna River. USACE is preparing an environmental assessment (EA) in compliance with the National Environmental Policy Act of 1969, as amended, to evaluate potential impacts of modified operations to lake and downstream water quality, submerged aquatic vegetation, wetlands, fish, recreation, and other considerations. Potential impacts could result from altered magnitude, frequency, duration, and seasonality of lake drawdown and downstream flows.
