Hydrologic and Hydraulic 
Dam Breach Analysis
Lake Renee Dam, Pike County, Pennsylvania
F. X. Browne, Inc. performed a dam breach analysis for inundation mapping downstream of Lake Renee Dam. Upon approval of the hydrologic and hydraulic analysis by PADEP, we developed an Emergency Action Plan for the dam.
As part of this effort, we modeled Lake Renee Dam under the following potential scenarios: sunny day failure, spillway design flood without failure, and spillway design flood with failure. We also modeled potential failures of Marcel Lake Dam, Silver Lake Dam, Nyce Lake Dam, and Beaver Pond Dam located downstream of Lake Renee and determined the corresponding flood water elevations in the downstream channel down to the Delaware River. The results of this dam breach analysis were used to generate inundation maps for Lake Renee’s Emergency Action Plan.
