**Location & Facility:** Sandy Shore Drive provides public boat ramp access to the Big Eau Pleine Reservoir in Mosinee, Marathon County. This concrete ramp offers a convenient launch point for kayakers, canoeists, and motorboats accessing the 6,348-acre reservoir.
**Water Conditions & Recreation:** The Big Eau Pleine Reservoir is a large, deep freshwater lake with a maximum depth of 46 feet, making it suitable for various paddling and boating activities. The calm reservoir waters are ideal for recreational paddling, and the lake is well-known for fishing opportunities including Musky, Smallmouth Bass, Northern Pike, and Walleye. Paddlers should note that if planning longer river trips, the stretch from Highway 153 to other ramps like Maryel Drive covers approximately 2.2 miles of flowage.
**Practical Tips:** As a public access point, Sandy Shore Drive is one of several boat landings providing access to the reservoir. Plan your trip according to current water levels and reservoir conditions, which are actively managed by the Wisconsin Valley Improvement Company. Contact local authorities or check current conditions before launching, especially if planning multi-ramp paddling routes.
