Acquisition: The Forestry, Fish and Game Commission of Kansas purchased original portions of the land in 1929. Another land purchase in 1930 completed the property to its current size. Construction of the lake began in 1930, and the area was opened to fishing and hunting in 1932.

Area Description: The lake is 160 acres in size and has a diverse, high quality fishery. The lake was renovated in the mid 1990?s, which included the addition of many brushpiles, rock humps, and a gravel spawning bar to enhance lake habitat. The most fished for species is the population of largemouth bass, which can be described as good to excellent. Channel cat fishing is also good. The lake also has fair populations of bluegill, black crappie, redear, walleye, wiper, and flathead catfish.

Fishing piers, fish feeders, a boat ramp, primitive camping areas, two shelter houses, four vault restrooms, and picnic tables are provided for area users.

The Leavenworth Wildlife Area is 341 acres consisting primarily of timber with some open grassland areas. These grassland areas are prime examples of historic native prairie that once dominated this area. Management techniques employed on the wildlife area include prescribed burning, timber encroachment control, and control of invasive plant species.

Deer and turkey commonly use the wildlife area. Squirrels and rabbits are also found on the area in good numbers. Other wildlife that may be seen at Leavenworth State Lake includes all furbearers, waterfowl, amphibians, reptiles, and both resident and migrating songbirds. Upland birds may also potentially be found on the area. Hunters and trappers are reminded to be considerate of other public users as well as surrounding neighbors with domestic pets.
