The image on this page was taken from an out-of-print book, published in 1985, entitled The Inland Fishes of New York State. It is a comprehensive field guide for species identification, and includes a distribution map for each species.
Since the copyright is owned by State DEC, it has been scanned in its entirety (at 400 dpi), and the entire volume was freely distributed by the State of New York. The link from where we downloaded it in 2006 is now dead, so we’re making it available here:
