The marsh is a public hunting area; no target practice is allowed. Only non-toxic ammunition is allowed.

The marsh is a memorial to honor the late Jim Ketelsen, an avid outdoorsperson and supporter of the Ducks Unlimited Greenwing program. He died while hunting ducks along the Des Moines River. The area was acquired in 1987 through the partnership of several agencies: Ames Chapter of the Izaak Walton League, Anderson Lake Sportsmen, Inc., Big Bluestem Audubon Society, friends and family of Jim Ketelsen, Iowa Department of Natural Resources, Habitat Stamp Grant program, Dr. Gerald Johnson, Story County Pheasants Forever, and Iowa Natural Heritage Foundation Wetlands for Iowa Program.
