Photograph of a part of a 17 acre planted, flooded field and a water control system in a hardwood bottom for ducks. The cultivated field was planted to browntop millet in July and the seeds produced were flooded in October. The flooded hardwood bottom made the acorns produce on the Nuttall oak trees. The hardwood area is drained during the summer so as to not kill the trees. Over a thousand mallards were using this field the day the picture was taken.
