Special Note: The U.S. Fish and Wildlife Service's primary objective for the Grasslands Wildlife Management Area is to protect wetland habitat. Through the use of one-time payments of Duck Stamp Act funds, private landowners have agreed to perpetually maintain the wetlands and associated upland habitat. The current size of this management area is 30,000 acres.

No Public Use : The public is not permitted on this area as the Service did not acquire public use rights. This area was established primarily to protect wintering waterfowl. There are several county roads (especially Santa Fe Grade) that provide public vehicular access through these wildlife-rich marshlands.
