The Mullett Lake Area Preservation Society (MAPS) is a  Michigan non-profit corporation established with the mission of keeping Mullett Lake and its surrounding watershed healthy for generations to come.

A lake is a massive ecosystem that requires balancing nature with human enjoyment—that is where the Mullett Lake Area Preservation Society (MAPS) plays a role, along with a number of other agencies who assist us in translating the science of water quality and shoreline integrity into sensible application by property owners.

Whether you love Mullett Lake for fishing, boating, or just the amazing views, please join us!

Special thanks to Tip of the Mitt Watershed Council for their continued work toward our mission. All Tip of the Mitt maps, reports, and data are used with permission.

• 4th largest of 5 ‘Giant’ Lakes in Northern Michigan

• 17,000+ acres of surface area

• Depth of 144 feet

• Approximately 1,100 homes on its shoreline

• Approximately 39 species of fish (according to 2017 Survey)

• The lake is named after John Mullett, who, together with William A. Burt, made a federal survey of the area from 1840 to 1843. A neighboring lake was named after Burt.

• The lake is approximately 10 miles (16 km) long from southeast to northeast, about 4 miles (6.4 km) at its widest.

• Major inflows to the lake are the Indian River, which connects with nearby Burt Lake, Pigeon River, Little Pigeon River, and Mullett Creek.

• The Cheboygan River flows out of the northeast end of the lake.

• The lake is part of the great Inland Waterway, by which one can boat 38 miles (61 km) from Crooked Lake and Round Lake near the Little Traverse Bay of Lake Michigan across the northern tip of the lower peninsula’s so-called mitten to Cheboygan on Lake Huron.

• The Inland Waterway was a Native American trade route that was later opened to small steamer and modern recreational traffic.

• I-75 passes to the west of the lake, with two interchanges near the south end of the lake at the unincorporated community of Indian River. M-27 passes along the northern shore of the lake through the unincorporated communities of Mullett Lake and Topinabee, while M-33, running north-south, passes along a portion of the eastern shore through the community of Aloha.

• Mullett Lake is an excellent fishery, with a variety of game species, including brown trout, brook trout, rainbow trout, steelhead, splake, smelt, northern Pike, muskellunge, yellow perch, walleye, smallmouth bass, largemouth bass. Most notably lake sturgeon (the state record specimen was taken from these waters) are making a comeback.
