Kingman County State Lake is a 144-acre shallow impoundment located 7 miles west of Kingman, Kansas. The spring-fed lake has a sandy bottom with exceptionally clear water, averaging only 4 feet deep with a maximum depth of 11 feet. The eastern two-thirds of the lake serves as a waterfowl refuge, while the western third is open for general use.

The lake is surrounded by riparian woodlands and rolling sand prairie, creating an attractive setting for paddling. The area ranks among Kansas's top 13 locations for wildlife viewing. Paddlers can expect to see various waterfowl and shore birds. The forested shoreline provides both scenic value and wildlife habitat.

Primitive camping facilities are available along the eastern shoreline, including picnic tables, fire rings, vault toilets, and one picnic shelter. Note that drinking water is not available on site. A boat launch facility is provided for water access.

The lake was originally constructed in 1932 around a historic wetland known as "Callahan Marsh" and was expanded to its current size in 1955. Motorized boats are permitted but restricted to fishing purposes only. The shallow nature of the lake and abundant aquatic vegetation should be considered when planning paddle routes.

Water quality is typically good due to the spring-fed nature of the lake. However, during summer months, vegetation can become thick which may affect paddling in some areas. The lake contains multiple fishing piers that paddlers should note when navigating.

Public access is managed as part of the Kingman State Fishing Lake and Wildlife Area, with facilities focused primarily on fishing and wildlife viewing. As of 2024, the lake is designated as an Aquatic Nuisance Species water body, requiring boats to be drained and drain plugs removed before transport on public highways.
