Allegheny River Professional Review and Guide
"Rising in Pennsylvania’s Potter County, the Allegheny River comes up to New York as a wide, slow-moving stream averaging 4 feet deep, punctuated with holes up to 12 feet deep. Only running through New York for about 40 miles, totally within Cattaraugus County, it slices through two cities and ends its tour of the state on Seneca Allegany Indian Territory as the Allegheny (Kinzua) Reservoir.
In Pittsburgh, Pennsylvania, it joins the Monongahela River to form the mighty Ohio River. Key species: Muskellunge, northern pike, walleye, smallmouth bass, channel catfish, bluegill, and rock bass"
