Moon Lake is a 71-acre lake located near Montello in Marquette County, Wisconsin, offering public boat access via a dedicated launch ramp. The lake has a maximum depth of 12 feet, with an average depth of around 5 feet, making it suitable for kayaks, canoes, and small motorboats. The McMillan Boat Launch off Moon Lake Road is the primary public access point, though multiple launch options are available around the lake.
This modest-sized lake is ideal for casual paddling and fishing, with populations of panfish, largemouth bass, and northern pike. Paddlers can explore the lake and access a small public beach area via a wooded path or short paddle. While the lake itself is privately owned, the public access point ensures boaters and paddlers can enjoy this scenic Marquette County water body. The shallow average depth means conditions are generally calm, making it a good option for beginners and families.
