                                        A recurring issue in groundwater resource management is how to present a 
                                        synoptic overview of the changing status of groundwater resources in a way that 
                                        is useful to senior managers and other decision managers. At small scales, and 
                                        with an abundance of data, contour maps of changes in water levels might be the 
                                        most appropriate tool. However at the regional scale that the workers were asked 
                                        to deliver a product there is simply too much heterogeneity in aquifer 
                                        characteristics, and too little data, for water level contours to indicate 
                                        useful information. The data can be presented in long reports with many graphs, 
                                        but this does not give a synoptic geographic overview. A compromise approach was 
                                        therefore selected of using water levels from indicator boreholes, depicted 
                                        geographically on a map, using "groundwater stress" as a backdrop. (Groundwater 
                                        stress is defined here as groundwater use divided by groundwater exploitation 
                                        potential).
