ALLEGHENY RIVER HISTORY. Location: A river rising in north-central Pennsylvania and flowing about 523 km (325 mi) northwest into New York then southwest into Pennsylvania again, where it joins the Monongahela River at Pittsburgh to form the Ohio River.
The Susquehanna River flows from New York, through Pennsylvania and Maryland, and into the Chesapeake Bay a total of 440 miles. Almost half of Pennsylvania lies in the Chesapeake Bay Basin. The Susquehanna has an average flow of 19 million gallons of water per minute. The river supplies 50% of the freshwater entering the Bay, and is the Bay's largest freshwater contributor. The Potomac River, also located in parts of Pennsylvania, contributes an additional 2% of the Bay's freshwater.
