The Fulton Chain of Lakes is a string of eight lakes located in the Adirondack Park in upstate New York, United States. The chain is the dammed-up Moose River, and the dam which creates the chain holds back nearly 6.8 billion US gallons (26,000,000 m3) of water. The lakes are located in Herkimer and Hamilton Counties. Inlet, Old Forge, and Eagle Bay are towns on them. The chain begins near Old Forge and ends before it reaches Raquette Lake. The lakes are named for Robert Fulton, inventor of the steamboat, who proposed connecting the lakes to create an Adirondack canal. They are suitable for pontoon boats (the most popular type in the area), kayaks, and motorboats. The chain is part of the 740-mile (1,190 km) Northern Forest Canoe Trail, which begins on First Lake and ends in Fort Kent, Maine.
The lakes in the chain have been given ordinal designations: First Lake, Second Lake, Third Lake, Fourth Lake, Fifth Lake, Sixth Lake, Seventh Lake, and Eighth Lake. The chain begins with a small lake not counted in the series called Old Forge Pond. In reality, First, Second and Third Lake are one long lake separated by narrow straits. At the east end of Fourth Lake, by Inlet in Hamilton County, a stream, or channel, allows access to the small Fifth Lake. A portage is necessary to arrive at Sixth Lake, which is also connected by a narrow strait to Seventh Lake. Another portage is required to gain access to Eighth Lake.
