Big Deer Pond in Hamilton County, New York is located approximately 1.5 west of Lows Lake in the Five Ponds Wilderness Area and the Adirondacks "Bob Marshall Wilderness" area (there is another in Montana). It serves as a 1/2 mile water-portage between Lows Lake and the upper Oswegatchie River. The portage is a total of 3.5 miles through blowdown of virgin timber. Big Deer Pond is noted for being a large shallow pond with numerous bog plant life. It was initially named Lost Pond by surveyor Verplanck Colvin before being rediscovered by conservationist Bob Marshall (wilderness activist) after the turn of the 20th century.
