Mill Creek is a tributary of the Clarion River in Clarion and Jefferson counties, Pennsylvania in the United States.[5] [6]
Mill Creek joins the Clarion River near the borough of Strattanville.[5]
The Pennsylvania Fish and Boat Commission stocks the creek with brook trout three times per year, first in the spring before the opening day of the Pennsylvania trout season then two in-season stockings during May.
