Marcy Dam

Marcy Dam is a wooden dam on the Marcy Brook in the Adirondack High Peaks in North Elba, New York, USA; it impounds Marcy Dam Pond. It can be reached only by hiking; it lies 2.1 miles from the Adirondack Loj at an elevation of 2,362 feet (720 m) surrounded by Whales Tail Mountain, Wright Peak, Algonquin Peak, Avalanche Mountain, Mount Colden, TR Mountain, and Phelps Mountain.

Marcy Dam is a popular camping spot for hikers in the high peaks. The New York State Department of Environmental Conservation maintains an Interior Outpost on the western shore. There are a number of campsites and lean-tos in the area, and trails lead from the dam to most of the high peaks; Mount Marcy is 3.5 miles to the southeast.

During Huricane Irene, the dam was damaged due to flooding and the pond was partially drained. The trail that went over the dam has been rerouted downstream.
