Burt Lake is a 17,120 acre lake in Cheboygan County in the U.S. state of Michigan. The western shore of the lake is on the boundary with Emmet County. The lake is named after William Austin Burt, who, together with John Mullett, made a federal survey of the area from 1840 to 1843.The lake is approximately 10 miles long from north to south, about 5 miles at its widest, and 73 feet at its deepest. Major inflows to the lake are the Maple River, which connects with nearby Douglas Lake, the Crooked River, which connects with nearby Crooked Lake, and the Sturgeon River which enters the lake near the point where the Indian River flows out of the lake into nearby Mullett Lake.The lake is part of the Inland Waterway, by which one can boat from Crooked Lake several miles east of Petoskey on the Little Traverse Bay of Lake Michigan across the northern tip of the lower peninsula's so-called mitten to Cheboygan on Lake Huron. Along with nearby Mullett Lake and Black Lake, it is noted for its population of Lake Sturgeon, which briefly held the record of largest sturgeon caught in the USA.
