Recharge rates under pristine conditions estimated from the groundwater balance method were of the order of 0.02-0.14 mm/yr and 0.05-3.0 mm/yr using the chloride method. Recharge was greatest in the deep sandplain and arkosic-outcrop soil associations and least in the heavy textured midslope and valley soils. Clearing of the native vegetation for agriculture is estimated to have increased groundwater recharge by between one and three orders of magnitude. Equilibrium groundwater balance estimates suggest
