New York - Species Distribution Maps
Brown Trout Distribution
Source: Inland Fishes of New York
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 is available for free download from the following site:

For your convenience, I've extracted the distribution maps for Brook Trout, Brown Trout and Rainbow Trout. These PDFs capture all of the resolution that is in the original scan by the State of NY. Each is roughly 2,000 pixels wide and is around 1.2 MB to download. The files are optimized for screen viewing. To print them, you'll either need to do it in sections, or have Adobe Acrobat reduce it to fit the page (very easy in the latest Acrobat Reader 7)
It's also instructive to view overlay this view of trout distribution with the color image of brook trout distribution we put on the main NY streams page.
Here's the Inland Fishes Brown Trout Distribution on top of the color brook trout image:

I've found it interesting to speculate on both the consistencies and inconsistencies of these data. Keep in mind the significant age difference. But it also points out the difference in methodologies: in particular, distribution maps such as Inland Fishes, which merely indicate a spot if a survey finds the species, say as much about where surveys have been performed as they do about fish distribution.
