Point Marion Lock and Dam, located on the Monongahela River in Pennsylvania, was completed in 1959 by the US Army Corps of Engineers. This gravity dam with a multi-arch core stands at a structural height of 52 feet and serves primarily for navigation purposes. The dam has a spillway width of 420 feet and a controlled spillway type, with a maximum discharge capacity of 55,000 cubic feet per second.

With a hazard potential rated as significant, the dam is continuously monitored and managed by the US Army Corps of Engineers to address flood risks. Regular inspections and maintenance are conducted, and emergency action plans are regularly updated to ensure preparedness in case of a dam-related emergency. Despite the dam's limited storage capacity, measures are in place to manage water levels and relieve pressure to maintain its structural integrity during severe weather events.

Overall, Point Marion Lock and Dam plays a crucial role in managing water resources and climate-related challenges in the region. The dam serves as a vital infrastructure for navigation and flood risk management, demonstrating the importance of ongoing monitoring and maintenance to ensure its effectiveness in safeguarding the surrounding communities and environment.
