Hackberry Flat WMA covers 7,120 acres of southwestern Tillman County in Western Oklahoma. Located southeast of the town of Frederick, Hackberry Flat WMA is a combination of upland and wetland habitats.
The 3,700 acre wetland development unit consists of a variety of plants such as millet, sedges, and smartweed, and some agriculture fields. Uplands consist of agriculture fields, native grasses, improved grasses, and forbs, interspersed with mesquite, hackberry, Osage orange, black locust, and sand plum. The average annual precipitation for the area is approximately 27 inches.
Most water in wetland units comes from rainfall runoff. Rainfall amounts in this region greatly fluctuate between years; therefore, the number of wetland units flooded at any given time is highly variable.

Approximately 90 water control structures, 35 miles of dikes, 4 miles of water distribution canals and 25 wetland units have been constructed to provide wetland wildlife habitat. In addition, there is a pipeline that delivers 2,400 acre/feet of water annually to Hackberry Flat. Management efforts focus on producing native wildlife foods such as wild millets, sedges, smartweeds, pigweeds, ragweeds and sunflower. Agriculture crops such as milo, foxtail millet, Japanese millet, and wheat are planted on approximately 1,300 acres annually. These fields are planted for both dove and waterfowl feeding fields.
