Saratoga Lake is a lake in the eastern part of Saratoga County, New York. The lake is approximately 4.5 miles long, about 1.5 miles wide at its widest point, and about 95 feet deep.
The Lake is surrounded by the City of Saratoga Springs on the north west, the Town of Malta on the south west, the Town of Stillwater on the south east, and the Town of Saratoga on the north east. New York State Route 9P is a highway that runs along the southern end and eastern side of the lake, and then crosses its outlet in the north.
The lake's major source is the Kayaderosseras Creek which enters the lake from the north west, and the outlet is Fish Creek, which exits the lake from the north and flows into the Hudson River at Schuylerville, New York.
