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.
Ortmann noted that the river flowed âblackish-brownâ all the way to the Allegheny River and it appeared to be devoid of aquatic life. By 1996, however, portions of the Clarion River were included in the Federal Wild and Scenic Rivers System.
