Cooper's Prairie Marsh is a 40 acre property in central Story County. This is a public hunting area with upland and waterfowl species; no target practice is allowed; only non-toxic ammunition is allowed.
This land was acquired from Robert Cooper in 1976. Prior to acquisition, part of the area was farmed. However, the naturally occurring pothole on the site fills with several feet of water each spring. The agricultural land has been converted to restored prairie, and a parking area was installed in the southeast corner of the marsh.
