D- 15 2000 Major recharge events occurred in February and April. Figures-D 14 to 17 show the progressive rises in water level. Figure-Ds 18 to 21 show differences between stages. In Figure-D 21 it can be seen that as in 1975 the largest rise of up to 2 m occurred in the west of the basin, compared to around 0.8 m near the Todd. About 1 m of water level rise in the western areas must be due to direct infiltration, or about 70 mm of rainfall. Rises in water level near the Todd were about 0.4 m, hence it was assumed that rises above this over the rest of the basin were diffuse recharge. An increase in saturated volume of 6233129 m3 was calculated, giving an increase in storage of 436 ML. The assumed area of the Southern Zone is 5.3 km2, giving an average recharge of about 80 mm. 383000 384000 385000 386000 387000 7376000 7377000 7378000 7379000 7380000 3048 4956 4957 5801 5802 5803 5806 5808 5818 5820 5824 5825 5826 10990 11050 11053 11134 11216 13238 13625 13763 13912 13914 13915 13916 13917 13918 1392013921 13922 13923 15094 16250 163651636616367 16605 16606 06/03/2000 Figure-D 15 Potentiometric Surface 03/00
