Some additional South African examples of successful artificial recharge may be of interest to supplement Dr. Enslin's able review. The only large-scale operations known to the writer have been undertaken at Zebediela Estate near Potgietersrus. On a visit in 1955 it was seen that all three methods were used:- (i) Floodwater was diverted from the Mogoto Dam back into the river to ensure streambed infiltration. (ii) Stormwater and surplus impounded water were diverted or pumped into earth dams in the vlei area to recharge a 40 to 150 ft. thick layer of rubble overlying Bushveld basalt. (iii) Four boreholes were used in a Dolomite area.
