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, and some species information released by the NH Fish and Game Department (shown here), 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 trout data published by NH Fish and Game, displayed in Google Earth. You can download the complete dataset in KMZ form, which can be used in Google Earth. Unlike the EBTJV data, which is based on a quantitiative model, this data is based on surveys. The pink areas are watersheds holding rainbow trout. Brown codes brown trout. Green is brook trout. The brook trout layer is on the top; brown trout on the bottom. The individual brown and rainbow data are shown below.
