Hydropower

Because of hydropower’s significant advantages over other energy sources — clean, efficient, reliable and renewable — it plays an increasingly important role in meeting the nation's energy needs. Within the Mississippi Valley Division's boundary:

    • Four Corps plants produce 226.5 megawatts of power:

       - Clarence Cannon Dam on the Salt River at Monroe City, Missouri.

       - Narrows Dam on the Little Missouri River at Murfreesboro, Arkansas.

       - Blakely Mountain Dam on the Ouachita River near Mountain Pine, Arkansas.

       - DeGray Dam on the Caddo River near Arkadelphia, Arkansas.

    • Eight non-federal plants (four private, four municipal) at Corps dams on the Mississippi and Illinois rivers provide 395 megawatts of power.
