Deskripsi
English:

from north end of island, facing upstream

This series of photos was taken on July 12, 2005, on and near NPS Island 112-02 during a canoe safety training for new staff. The images depict construction by the U.S. Army Corps of Engineers of a partial closing structure made of riprap, dredged material and live plant material. The purpose of the structure is to control erosion on the upstream end of the island and to create new wildlife habitat. This project is part of the Corps' Channel Maintenance Management Plan. NPS Island 112-02 is located in Mississippi River Pool 2 at River Mile 827.5
