Dr K.R. Miles, following his recent study of the Underground Water Resources of the Adelaide Plains area, advocated artificial recharge and put forward several suggestions for practical consideration. The following may be considered supplementary, in particular it summarises the results of recent experiments, and at the same time puts forth additional recommendations. It is significant to note from the attached comparative chart, for the recorded period at least, that providing pumping draught tapers off during the winter and early spring season the recovery of the hydraulic surface of the water in the basin, following natural winter recharge, rises to a fairly constant level regardless of greater, or less, than average rainfall. For example, the attached hydrographs of the Holbrook Bridge and Wolseley Government bores, which can be considered representative, show that during the years 1947-1951 inclusive little difference has been recorded in the seasonal peak levels, i.e. there is practically no difference in the September, 1949 level after a dry winter than the September, 1951 level after an abnormally wet winter. Unfortunately peak readings in 1950 were not taken and therefore it cannot be conclusively shown that the water level made full natural winter recovery after a recharge in 1950. It is also noticeable that in drier than average 1949, full recharge level (as compared with years 1947 and 1948) was attained in September prior to the peak monthly rainfall in October.
