Wild Rice River Structure

The U.S. Army Corps of Engineers, St. Paul, Minnesota District has a requirement entitled: the Wild Rice River Structure. This work is part of the Fargo Moorhead Metro Area Flood Risk Management (FMM) Project. The work site is near Fargo, ND (Cass County).

The work includes, but is not limited to all plant, labor, and materials to construct a gated water control structure, dam walls, a vehicle service bridge, stilling basin, pre-formed scour hole, approach apron, a slope protection slab and approach walls. The control structure contains two, forty foot wide tainter gates, a ten foot wide concrete pier between them and abutments on the east and west side of the dam. Full height dam embankments will be constructed to within approximately two hundred and sixty feet of the control structure. A combination of partial height dam embankment and dam walls will connect the control structure to the full height dam embankments. The dam wall footings will be at roughly the existing ground elevation. The abutments, stilling basin walls and upstream training walls of the control structure will retain embankment material up to the top of the dam wall footing elevation. There will be a one hundred and twenty-five foot long stilling basin with a dentated end sill and a twenty-foot deep pre-formed scour hole to dissipate energy. An eighty-five foot long concrete approach apron will be built on the up-river side of the structure. The project also includes a control building, access roads and approximately one thousand and nine hundred feet of engineered channel.
