Its headquarters is on the northeast side of Lac qui Parle Lake between the towns of Watson and Milan. Made up of wetlands, brushlands, woodlands, native prairie, and other grasslands and cropland. Natural wetlands and man-made impoundments provide habitat for waterfowl, shorebirds and aquatic furbearers.
Most wetlands are near the lakes, but some upland areas contain marshes and smaller impoundments.
More than 2,000 acres of corn food plots are planted each year by local farmers and WMA personnel to provide feed for geese, deer and other wildlife. Native prairie nesting cover is maintained by controlled burning. Tree plantings are established to winter and escape cover. Water levels of impoundments are manipulated to maintain aquatic plant growth and enhance wildlife habitat. Geese are the most commonly hunted species, followed by duck, deer, and pheasants.
