The average of the pan coefficients for these two depths has been used. Monthly evaporation for the Alice Springs dam'is shown in Table 4.

These relationships are based on 1:2400 photograrnmetric contour maps. Forbes (1965) determined similar curves for the damsite from 1:2400 stadia survey contour maps. The relationships shown in Figure 3 and those derived by Forbes are within 5% of each other.
