Maxwell Locks and Dam, also known as Maxwell Pool, is a gravity dam located in Brownsville, Pennsylvania, along the Monongahela River. Built in 1964 by the US Army Corps of Engineers, this dam serves primarily for navigation purposes, with a hydraulic height of 31 feet and a structural height of 56 feet. The dam features two locks, with a length of 720 feet and a width of 84 feet each, allowing for the safe passage of boats and barges along the river.

With a storage capacity of 30,900 acre-feet and a drainage area of 4,961 square miles, Maxwell Locks and Dam plays a crucial role in managing water levels and preventing flooding in the region. The dam is equipped with a controlled spillway, five Tainter (radial) outlet gates, and a spillway width of 420 feet to regulate the flow of water downstream. Despite its significant hazard potential, the US Army Corps of Engineers actively monitors and manages the dam's risks through regular inspections, maintenance, and emergency preparedness measures to ensure the safety and integrity of the structure.

In the face of increasing climate variability and severe weather events, Maxwell Locks and Dam remains a vital piece of infrastructure for water resource management and flood control in Pennsylvania. With a commitment to risk management and public safety, the US Army Corps of Engineers continues to prioritize the maintenance and operation of this essential structure to safeguard the surrounding communities and waterways from potential hazards and emergencies.
