Beltzville Lake was constructed by the U.S. Army Corps of Engineers in 1972. The multi-purpose project was authorized by Congress primarily for flood risk management, water supply, and low flow augmentation; and authorized secondarily for water quality and recreation purposes. The Pennsylvania Department of Conservation & Natural Resources manages the 3,002 acre Beltzville State Park surrounding the lake, which attracts numerous visitors each year.
The dam is located on Pohopoco Creek 5.2 miles from its confluence with the Lehigh River and 4 miles east of Lehighton, Pennsylvania. Beltzville Dam operates as a system in conjunction with Francis E. Walter Dam, located in White Haven, to reduce flooding in the downstream communities along the Lehigh River. Since it's construction in 1972, the dam has prevented more than $41 million in flood damages to date.
