-67- In the eastern Pine Hill area, a SWL of 23m was recorded for Desert Bore (RN 6460) by the driller in 1960. The SWL in 1984 was 19..9m, indicating a rise in water table over the period, but the 1964 data is considered to be unreliable and without supporting data from other bores. Mr R. Purvis of Atartinga Station (pers. comm.) reports a rise in water level of several metres in many of his stock bores after 1974/75 rains, but most of these bares are in the eastern margins of the Ti-Tree Basin. He also cites the example of Pigeon Well (not registered) in the vicinity of RN 12484 on Atartinga P.L. This well was sunk in the 1930's, to a depth of 21m. With the equipment available at that time the well could not have been sunk more than a metre or so below the water table. The water level in the well measured several years ago by Mr Purvis was only 12m, implying a rise in water level of around 8m. Monitoring data in the central Ti-Tree Basin has been collected only since 1980. The greatest change in water level seen is in RN 12156where a steady fall in level has occurred, with total decline in head since 1980 of 1. Sm. Anecdotal evidence of streamflow, or overland flow, after high rainfall event is scant, mainly because of the remoteness of the area and the difficulties of moving about in an area of unformed roads after rain. Mr H Purvis (pers. comm.) reports extensive overland flow in the area west of Merina Bore (RN 14385) after rains in 1968,1974 and 1983. This flow would result from runoff arising on the weathered basement rocks on the eastern margin of the basiri
