5.3 Water Table 5.3.1 Groundwater Monitoring Some water level measurements were made in 1938-9, and the Army conducted measurements 1941-4. These early measurements have not been incorporated into the data-base. The earliest water level hydrographs in the DIPE database commence in 1952. Over the years water levels have been monitored in a total of 74 bores. Currently 38 are being monitored. Two of the bores monitored have measurements going back to 1952 and six are pre-1960. Wilson (1958) presents graphs of short hydrographs for numerous bores. Much of this data appears to have been lost. The graphs refer to bores bore by the lot numbers at that time, and it would be difficult to match these with RN s. These records contain information on lag times that is not available from later less frequent monitoring. In addition up to 10 years of water level data for individual bores are stored in the bore folders and have not been entered into the HYDSYS database. Most hydrographs have a gap from about early 1972 when the Town Basin was perceived to be of no further importance until mid 1975 when problems with rising water levels were apparent. As a result the large rise that occurred in the very wet year of 1974 is poorly documented. A summary of monitoring bore data is shown in Appendix B. Locations of all monitoring bores are shown in Figure 6 . There is little data available for the fringes of the basin. Power Water have a large amount of videos of sewers, in some of which groundwater can be seen to be entering the sewers, but it has not yet been possible to get this data in a useful form. 16
