Allegheny River Lock and Dam 6, also known as Allegheny River Pool 06, is a gravity dam located in Freeport, Pennsylvania. Completed in 1928, this federal-owned structure serves primarily for navigation purposes on the Allegheny River. With a hydraulic height of 21 feet and a length of 1212 feet, the dam has a storage capacity of 14,000 acre-feet and a maximum discharge of 120,000 cubic feet per second.

Managed by the US Army Corps of Engineers, Allegheny River Lock and Dam 6 is equipped with a single lock measuring 360 feet in length and 56 feet in width. Despite its low hazard potential, the dam plays a crucial role in mitigating flood risks by releasing water to manage levels upstream and downstream. Regular inspections and maintenance are conducted to ensure the structural integrity of the dam and to address any potential issues that may arise.

In times of severe weather events or unpredictable water inflows, the USACE implements risk management measures to safeguard the dam and surrounding areas. This includes continuously monitoring the dam's condition, collaborating with local emergency managers, and updating emergency action plans. With a moderate risk assessment rating, ongoing efforts are in place to enhance preparedness and response capabilities in the event of a dam-related emergency.
