NCMRWC Roy Blunt Multi-Purpose Reservoir *REBID*

Description: Construction submittal consists of constructing a 78'-high zoned earthen dam. The principal spillway is a single cycle 83.7'-long labyrinth weir discharging to a 55'-wide concrete chute on the left abutment. The concrete chute transitions to a riprap lined open channel with five grade control structures. A riser will be constructed to house the reservoir drawdown capabilities. The 60-inch draw down conduit will outlet to an impact basin. A blanket drain, filter diaphragm and spillway underdrain system will be installed. A cement bentonite slurry wall and grout curtain will also be constructed.
