Welcome to Francis E. Walter Dam & Reservoir

The Francis E. Walter Dam was constructed by the U.S. Army Corps of Engineers in 1961 and has prevented more than $220 million in flood damages. It also supports recreation in the Lehigh Valley with planned fishing and whitewater rafting water releases.

Francis E. Walter Dam was constructed in 1961 by the U.S. Army Corps of Engineers. The dam was primarily built for flood risk management, but recreation became a Congressionally-authorized purpose in 1988. F.E. Walter Dam operates as a system in conjunction with Beltzville Dam, located in Lehighton PA, to reduce flooding in the downstream communities along the Lehigh River. Since its construction, the F.E. Walter Dam has prevented more than $245 million in flood damages to the Lehigh River Valley.

In recent years, funding was used to upgrade roads, upgrade electric, repair cracks in the intake tower, repair concrete on the gravity wall and outlet structure, and grout the dam to address seepage issues.

Since 2005, the U.S. Army Corps of Engineers Philadelphia District, in partnership with the Pennsylvania Fish and Boat Commission, Department of Conservation and Natural Resources, Delaware River Basin Commission, and stakeholders from both the nonprofit and private sectors, has employed a collaborative approach to managing flows out of the Francis E. Walter Dam into the Lehigh River.

Subject to the project’s primary mission of flood damage reduction, Francis E. Walter Dam Flow Management Working Group seeks to strike an optimal balance among legitimate yet sometimes competing interests in terms of natural resource management and recreational opportunities. Central to the group’s effort is development each year of a flow management plan that builds upon prior year success while identifying and incorporating areas of potential improvement.
