Habitat includes 633 acres of wetland and 454 acres of upland. One of the largest and perhaps best marshes for waterfowl during spring, This basin provides habitat for thousands of white-fronted geese, snow eese and ducks during late February and early March. Many wetland birds remain here to breed, including northern harriers, great-tailed grackles, and yellow-headed blackbirds.
Between 1997 and 2001 this marsh supported over 8,000 spring shorebirds. Best in spring, sometimes a dud but can be very good. There are several parking areas around the site’s perimeter and a kiosk with information in the southeast parking lot. Intense disking and burning coupled with grazing and pumping over the last few years have helped to decrease the dense stands of vegetation.
