This unique wetland was formerly one of the largest contiguous wetland complexes found within Oklahoma. Unfortunately, in the late 1960's the area was drained, cleared and converted for agricultural use. These drastic changes have reduced, in some cases even eliminated, important wetland values such as natural flood control. In a preservation effort, the Fund obtained 1,959 acres, which complemented the protection of 3,855 acres acquired in 1997, through a generous gift by the Richard King Mellon Foundation.
This restoration of historic wetland resources has had many benefits to the area. Already, many species of migratory birds long absent to this area, such as the White Ibis, are returning. Beyond ecological value, the enlargement of this natural area will have a cultural dividend as well. The local school system is interested in developing an outdoor classroom at the Red Slough. Additionally, sites containing artifacts of the Caddo and Choctaw tribes that once lived in the area were also preserved.
