    GEOHYDROLOGY                                    
The current estimate of actual groundwater use in the Breede River catchments is 103 million m3/a, much of which is abstracted out of the alluvial aquifers, and the Bokkeveld and Karoo fractured rock aquifers. The Table Mountain Group  aquifers of the Upper Breede sub-area are a potential source of supply, both for in-catchment use and for supply to the Berg Water Management Area (Ref.1.).
