Horseshoe Lake in Manitowoc County, Wisconsin, is a small 22-acre deep seepage lake with a maximum depth of 54 feet and mean depth of 25 feet. The lake gets its horseshoe-like shape from its 1. 2-mile shoreline configuration.

Located on County Highway XX, approximately 3 miles west of Highway 42 south from Manitowoc, the lake offers convenient access through Manitowoc County's 8. 5-acre park.

The primary access point features a concrete boat ramp with an 11% slope and greater than 3-foot launch depth, complete with a boarding dock that is ADA accessible. A pier serves dual purposes for launching and fishing.

Paddling is restricted to electric motors only with designated slow-no-wake areas. Launch fees are $5 daily or $20 seasonally, though enforcement is minimal and contributions support invasive species control efforts.

The lake maintains fair to eutrophic conditions with a Trophic State Index of 55, indicating decreased water clarity and occasional algae presence. Average summer Secchi disk readings reach 5 feet with green-tinted water typical during summer months.

The bottom composition is 95% muck with 5% gravel, creating a two-story lake environment. Horseshoe Lake supports diverse fish populations including rainbow trout (regularly stocked), largemouth bass, bluegill, northern pike, and walleye.

Aquatic invasive species present include Eurasian Water-Milfoil (since 1971) and Curly-Leaf Pondweed (since 2005).

Park amenities include picnic areas with grills and tables on the hillside northwest of parking, plus a lower-level shelter and restroom facilities. No potable water or lighting is available.

The lake's deep seepage characteristics and protected location make it suitable for year-round paddling, though spring through fall offers optimal conditions.

The combination of fishing opportunities, convenient facilities, and manageable size makes this an accessible option for paddlers seeking a straightforward lake experience near the Lake Michigan shoreline.
