St. Paul District
Description
Ambrough Slough is a side channel on the Wisconsin side of the Mississippi River in pool 10, about five miles upstream of Prairie du Chien, Wisconsin. The slough enters a 2,500-acre backwater complex of lakes and smaller sloughs. The site lies within the Upper Mississippi River National Wildlife and Fish Refuge. The entire area has experienced a loss of depth from siltation and aquatic plant decomposition. This limits the area of desirable fish habitat. The area is important spawning and rearing habitat for a variety of fish, but this importance is diminishing.
