Located in Philadelphia, Pennsylvania, the Water Control Structure on Darby Creek is a federal-owned dam with a primary purpose classified as "Other." Standing at a height of 10 feet, this earth dam with a buttress core type has a storage capacity of 960 acre-feet and serves a drainage area of 250 square miles. Despite its undetermined hazard potential and not having a current condition assessment rating, the structure has not been regulated, permitted, or inspected by the state.

While the Water Control Structure has not undergone recent modifications or inspections, its last known inspection date was in June 2004. With no emergency action plan (EAP) prepared or updated, the risk assessment and management measures for the dam remain unspecified. The structure's associated risk, inundation maps, and emergency contacts are also lacking information, presenting a potential need for further evaluation and preparedness in the event of an emergency or natural disaster. For water resource and climate enthusiasts, this structure serves as a point of interest for its location in an urban setting and its potential impact on the surrounding environment.
