New Hampshire is renowned for its upland brook trout streams.  However, until recently, very little information was available about them:  the state Fish and Game department lists only 16 wild trout streams out of the hundreds that exist.

In recent years, we've been able to develop two major sources, the EBTJV (shown here), and some species information released by the NH Fish and Game Department, which we've ported to KML and made availabe on Google Earth for the first time (see the Trout presence data) in the NH Resources menu.

The photo above shows the brook trout habitat dataset published by the Eastern Brook Trout Joint Venture, displayed in Google Earth.  You can download the complete dataset in KMZ form, which can be used in Google Earth.  If you don't use Google Earth (a decision you may wish to reconsider), you can download a detailed map based on an earlier version of this dataset.  Both are available in the "NH Resources" menu in the sidebar.  The color coding in the photo is as follows, in order of best to worst:

• Blue

• Green

• Yellow

• Orange

• Red

Areas which aren't coded with any color don't support brook trout.  Keep in mind that brook trout can be diminished by other trout species, so some red areas  (and even some blank areas) may be excellent wild brown or rainbow water.  But it's almost certain that the yellow and better areas are great places to find wild trout.

Note: these data are coded by drainage.  Not every stream within a drainage will hold trout, though the majority will, especially within the better habitat.
