River in Vermont

Vermont, world headquarters of the Orvis corporation, is best known for the Battenkill, which happens to flow through the back yard of the original Orvis store in Manchester. The Battenkill hasn't been stocked since 1971, and the fishery supports a mix of wild browns and brookies. Head into the Green Mountains (or any upland section in the state), and there's a good chance you'll find a small stream exclusively holding wild brook trout.
