Abstract: The four pumping stations (Cinque Hommes, Jones Cutoff, Bois Brule, and Missouri Chute) provide flood protection for about 26 ,800 acres of highly productive bottomland. Satisfactory hydraulic performance was obtained in the sumps for the Cinque Hommes and Jones Cutoff pumping stations by either extending wing walls from each side of the structures or by moving the timber trashrack closer to the sump and enclosing the rear and sides of the sump. Following the model studies of the sumps for Cinque Hommes and Jones Cutoff pumping stations, the design of the sump and trashrack for the Bois Brule pumping station was revised due to the high cost of building and maintaining the timber trashrack. The revised design, consisting of a classical trashrack and free-standing side and rear walls, performed satisfactorily. The model of the Missouri Chute sump indicated unsatisfactory flow due to adverse currents in the sump generated by lateral flow from a side channel located normal to the main channel. The mouth of the side channel was relocated farther upstream and satisfactory performance was obtained. The designs of the 45-deg saxophone outlets and channel configurations for the four pumping stations were similar. Design guidance for the size and extent of riprap needed in the exit channels was determined from the models.
