Mullett Lake is a central link in Michigan's famous Inland Waterway. The Indian River flows in from the south, connecting Mullett to Burt Lake (and beyond that to Crooked and Pickerel Lakes). The Cheboygan River flows north out of Mullett to Lake Huron, making it possible to boat from the interior chain all the way to the Great Lakes. The Pigeon River, Little Pigeon River, Sturgeon River, and Mullett Creek also feed into the lake.
At 148 feet deep, Mullett Lake is slow to freeze and ice thickness varies dramatically across the lake. Shallower bays and the south end near Indian River freeze more reliably than the deep main basin. Always check current local ice conditions — this is not a lake where you assume safe ice based on air temperature alone.

Mullett Lake is one of Michigan's largest inland lakes at 16,630 acres in Cheboygan County — about four miles wide with a maximum depth of 148 feet. That depth puts it in rare company for an inland Michigan lake and keeps the water cold and remarkably clear. Reviewers consistently mention being able to walk a quarter mile out on sandy bottom before it gets deep, and visibility that rivals much smaller lakes. The lake is a key link in the Inland Waterway — the Indian River connects it south to Burt Lake, and the Cheboygan River flows north out of Mullett to Lake Huron. That connectivity means you can boat a significant stretch of northern Michigan without trailering.
Fishing draws a lot of attention, especially smallmouth bass — multiple anglers report 3-5 pound fish with regularity. The deep, cold water also supports walleye, while the shallower bays produce bluegill and perch. Aloha State Park sits on the southeast shore and is the main hub for camping, swimming, and launching. The towns of Indian River (south end) and Topinabee (west shore) anchor the lake community, and multi-generational cottage families going back to the early 1900s give the lake a deep-rooted "Up North" identity. Three public launches serve the lake — the newer facilities get strong reviews for paved ramps and ample parking, though weeds can choke the channels at Aloha during peak summer.
