This is an aerial view looking south from above Pool 7 of the Upper Mississippi River near Trempealeau, WI.  The navigation dam which creates the pool appears slightly below the horizon in the upper left quadrant.  Wing dams are evidenced by the rippling water in the river channel as they direct the flow toward the main channel.  The complex backwater

This is an aerial view of Pool 7 of the Mississippi River south of Trempealeau, WI. This photo highlights the different habitats for plants and wildlife from the bluffs that parallel the river to its quiet backwaters. Balanced with that is the fact that the Mississippi River is a commercial highway as well as a haven for recreational uses.
