Burt and Mullett lakes are part of the famous "Inland Waterway”, a 40-mile long navigable system of lakes and rivers that flow from Crooked Lake northeast to Lake Huron. Maintained by the U.S. Army Corps of Engineers, the boating channel has a minimum depth of 5 feet and a width of 30 feet. Buoys mark a safe channel through Cheboygan, Indian and Crooked rivers. Flashing lights have been placed at the river entrances in Burt and Mullett lakes. Keep red channel markers on the right when going upstream and the black channel markers on the right when going downstream. Many restaurants, motels, marinas and stores are found along the entire route. The Coast Guard Cutter "Mackinaw” has its homeport in Cheboygan, Michigan.
