Monogahela River Navigation System
One of the nation's earliest and most successful river navigation systems, its series of locks and dams, begun in 1838, has provided year-round navigation between Pittsburgh and Fairmont, WV. Millions of tons of coal shipped through the locks supplied Pennsylvania's important coke, iron, and steel industries. Acquired by the federal government in 1897, the system has been expanded and modernized by the Army Corps of Engineers.
