The State of Vermont has officially designated 6 river segments as "wild trout streams" as part of a 5 year trial.  (Click on the icons in the map below to bring up a topographic map of each designated segment; click here for a list.)  In addition, several larger Vermont streams support wild trout populations and are presently managed without stocking including the Batten Kill, Castleton River from Ira to Fairhaven, Furnace Brook, and the Poultney River.

The above image was created in Google Earth.  It shows estimated brook trout habitat quality by subwatershed, overlaid with markers for each of the 6 WTS.  You can download from this website all of the information needed to recreate this image on your own Google Earth installation.  You can also click on an interactive map to zoom in on the markers in Google Maps.  Just click on the "VT Interactive Map" link in the VT Resources menu in the sidebar.

Of course, Vermont is best known for its hundreds of miles of upland wild brook trout streams.  These are not listed or mapped anywhere that I can find.  However, as is readily apparent in the photo, virtually any stream above 2,000 ft. (if it's large enough) should be outstanding habitat (all Vermont streams above 2,500 ft. are classified as Class A(1) by the Water Resources Board).
