The 77 acre Kinney Waterfowl Production Area contains approximately 26 acres of grassland, 32 acres of wetlands and 19 acres of upland forest. The wetland area is associated with the 150 acre Grass Lake, a portion of which is included within the area. In 2014 the Michigan Department of Natural Resources acquired most of the remaining portion of Grass Lake and the adjacent uplands totaling 385 acres and is now called the Cornish State Game Area.

The mixture of wetlands and grassland provides high quality nesting and brood-rearing habitat for ducks such as mallards and blue-winged teal as well as a variety of songbirds. Mallards, Canada geese and a variety of waterfowl use the area for nesting, brood rearing and during migration. A variety of wading birds, shorebirds and grassland birds are commonly observed on the property. Deer, rabbits and other mammals, as well as a variety of amphibians and reptiles, are also found on the area.
