Lake Nepessing is a 414-acre lake located 3 miles southwest of Lapeer, Michigan. A public DNR boat access site on the north shore off Hunt Road provides the primary launch point for paddlers, with a gravel parking area and concrete launch pads that can accommodate up to 16 boats.

The lake has an average depth of 10 feet and reaches a maximum depth of 25 feet, with 84% of the surface area being 10 feet or less in depth. The shoreline is moderately developed with residential properties, and approximately 50% of the shoreline is artificially armored with seawall. An unnamed outlet on the southeast shore flows to Farmers Creek, controlled by a metal standpipe structure that maintains a fixed water level at 831.7 feet above sea level.

Lake Nepessing is a warm-water, mesotrophic lake. During summer, the lake develops a thermocline between 17-22 feet deep. The lake supports diverse wildlife, including various fish species such as largemouth bass, redear sunfish, bluegill, and northern pike.

In 2012, the boat launch underwent improvements including paving of driveways and parking areas, installation of an accessible sidewalk, and addition of environmentally friendly features like permeable pavement and a native species rain garden to manage runoff.

While powerboats are permitted on the lake, the moderate size and relatively shallow depth make it suitable for paddling. The lake is shared by anglers and recreational boaters, and its size offers several hours of shoreline exploration opportunities.
