Mill Brook is listed as one of the top brown trout waters in Essex County by the New York State Department of Conservation.

Getting there

The easiest public access is from the Port Henry DEC boat launch at Powerhouse Park.

Fishing

Beginning at Lake Champlain, the brook winds its way back through Port Henry. The Essex County Fish Hatchery stocks almost 1,700 8- to 9-inch brown trout in Mill Brook every spring.
