Kiser Lake is a 396-acre lake with 5.3 miles of shoreline in west-central Ohio, known for its clean, clear waters. The lake is unique in that no motorized boats are permitted, making it an ideal destination for paddlers seeking a quiet experience. Four small launch areas and one boat ramp provide access points around the lake's perimeter.

The park's marina, open seasonally from spring through October, offers kayak and canoe rentals for those without their own equipment. Contact the marina at 937-362-3565 for rental information and current hours of operation.

The landscape surrounding Kiser Lake reflects its glacial origins, with rolling wooded hills and diverse wetlands. The Farmersville moraine surrounds the lake on three sides, creating distinctive elevated terrain. Large glacial boulders, known as erratics, dot the shoreline. The southeastern end features a kame field, where glacial meltwater created mounds of sand and gravel.

The lake stretches nearly 2.5 miles in length and supports a variety of wildlife. The adjacent Kiser Lake Wetlands Nature Preserve includes fen and wet meadow habitats with unique plant species such as pitcher plants, sundew, tamarack, and spruce.

Facilities include five fishing piers around the lake and several picnic areas with tables and grills. A 300-foot swimming beach operates from Memorial Day to Labor Day. The marina provides refreshments during its operational season.

The lake's creation stems from the vision of John W. Kiser and his family, who in 1932 offered several hundred acres of the former Mosquito Valley to the state of Ohio. The dam was constructed in 1939, transforming the spring-fed swampland into what is now Kiser Lake State Park.

Park hours run from 6 AM to 11 PM daily, though legitimate recreational activities are permitted outside these hours. For additional information, contact the park office at 937-843-2717.
