1) Shaw-Weil "Canoeing Guide to Western Pennsylvania"____ You can still find (used) 1991 edition on Amazon for about $15. does not appear that the 2005/2008 edition ever got published.
2) If anyone remembers the link to the streams of western PA (which is now defunct) showed all the rivers in the book on a spreadsheet like page, updated in real time apparently from river gages, and highlighted as runable or not. I always assumed they used the criteria from the book. Very cool. Sorry it's gone.
3) JT... The best over-all info and coverage of Ohio streams ( that I am aware of ) is below. These two 1983** volumes are classics. They are dated to be sure but still offer a wealth if information with write ups and maps. Each Volume covers about 30 rivers. These authors must have lived on the rivers. Used books are still on Amazon.
** Yikes...these are probably older than half of TCT members!
vol 1 = NW, SW, Scioto drainage vol 2 = NE, East, Muskingum drainage, S. Central
