Allegheny River (Mill Grove to Portville) Professional Review and Guide
"The Allegheny River is a wide, meandering waterway that rises in Pennsylvania, loops north through New York State then heads back down to Pennsylvania as a reservoir, with its waters backed up by the Kinzua Dam. It has a long history of human use, beginning as part of a portage route to the Mississippi River by the Native Americans and early explorers. From the early 1800s until the virgin pine and hemlock were depleted, lumber was a major product of the area. Olean was used as a collection point for rafts of lumber. Submerged posts in the river bed are evidence of old booms and dams that once controlled the flow of logs in the river. Today the Allegheny River is wide with a mild current (except during spring high waters) and often has high mud banks. Flood control dikes, set back from the water’s edge, parallel the river, making this feel like a river within a river. You can paddle most of the Allegheny, but some sections are more scenic than others."
