The U.S. Army Corps of Engineers, Philadelphia District, in partnership with the Delaware River Basin Commission and New York City Department of Environmental Protection, is conducting a feasibility re-evaluation study for Francis E. Walter Dam and Reservoir.
The study to date has evaluated an array of alternatives and screened out those which do not meet specific criteria in the planning study process such as raising the dam. Further evaluation of selected alternatives including structural modifications and operational changes have been ongoing to understand impact to the flood risk mission, recreation, and the environment.
On September 17, 2024, USACE, DRBC, and NYC DEP signed a feasibility cost sharing agreement amendment. This positions the study to ensure adequate time and resources to complete a full re-evaluation. This includes additional environmental modeling and engineering analysis. The study’s refined focus will consider future use of the Francis E. Walter Dam Reservoir during Delaware River basin emergency drought conditions to support/aid salinity repulsion in the Delaware Estuary, provide low flow augmentation, and protect aquatic.
Since this study effort exceeds allowed Congressional funding and time limits, an additional resource request was approved by the Secretary for increased time and funding to complete the needed engineering analysis. The study completion date is anticipated for March 2027 based on the additional analysis required.
