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.
From there, the water flows southward down the St. Clair River at the southern tip of Lake Huron through little Lake St. Clair and out the Detroit River to Lake Erie. Leaving Lake Erie, it flows north via the Niagara River and over Niagara Falls into Lake Ontario.
