The Great Sacandaga Lake (formerly the Sacandaga Reservoir) is a large lake situated in the Adirondack Park in northern New York in the United States. The lake has a surface area of about 41.7 square miles (108 km2) at capacity, and the length is about 29 miles (47 km). The word Sacandaga means "Land of the Waving Grass" in the native Mohawk language. The lake is located in the northern parts of Fulton County and Saratoga County near the southern border of the Adirondack Park. A small portion also extends northward into southern Hamilton County. The broader, south end of the lake is northeast of the City of Johnstown and the City of Gloversville. Great Sacandaga Lake is a reservoir created by damming the Sacandaga River. The primary purpose for the creation of the reservoir was to control flooding on the Hudson River and the Sacandaga River, floods which had a historically significant impact on the surrounding communities.
