The Schuylkill River has played a central role in the lives of generations of Philadelphians. In 1825, the Schuylkill Navigation Company completed 108 miles of dams, pools, locks, and canals that transformed the river into a premier route for boat traffic.
This vital transportation network connected Philadelphia to Pennsylvania's northern coal regions and to other natural resources upstream that fueled the city's industrial growth. Businesses also used the river to ship finished goods to consumers in nearby towns and beyond.

Frequent flooding and competition from railroads contributed to the decline of water routes as the primary form of industrial transportation in Philadelphia.
