Point Marion Lock and Dam, Navigation lock and gravity dam on Monongahela River, Pennsylvania.
Point Marion Lock and Dam spans across the Monongahela River with a length of 638 feet and creates an 11.2-mile upstream pool to Morgantown Lock and Dam.
The U.S. Army Corps of Engineers initiated construction in 1923 and completed this essential navigation structure in 1926 to enhance river transportation capabilities.
The lock and dam system represents the industrial development of Pennsylvania, enabling continuous maritime commerce between Pittsburgh and Fairmont, West Virginia.
The facility maintains a lock chamber measuring 84 feet wide and 720 feet long, accommodating vessels traversing different water levels of the Monongahela River.
The dam creates a reservoir with a capacity of 11,500 acre-feet, serving multiple purposes across a drainage area of 2,751 square miles.
