Runoff and sediment data for a reclaimed surface mined watershed and its sediment pond were analyzed to determine the pond trap efficiency and influent/effluent sediment and flow relationships. Reclamation practices on the watershed included topsoiling, a good vegetative cover, a rock chute, diversions, and dry dams. Relationships were developed to predict the total pond flow and the sediment concentration when the flow rate on the hydrograph recession was one-half the storm peak rate, and to predict the peak pond influent sediment concentration as a function of the same recession concentration. The trap efficiency for the study sediment pond averaged 93.7 percent as determined by storm influent/effluent sediment masses. The average storm influent sediment concentration was 23 times larger than the average effluent pond sediment concentration of 372 mg/1, and the average peak storm effluent sediment concentration was 1.55 times greater than the average effluent sediment concentration.
