The wettest year on record is 1973/74 with 926mm. The five year period from 1973/74 is the wettest period on record, the rainfall in each of these years being greater than the mean plus one standard deviation. 2.3 Stream flows 2.3.1 General The location of the four current gauging stations closest to the damsite are shown in Figure 1. Table 2 shows the catchment areas of the stations and of the damsite. An additional gauging station operated at the damsite from 1967 to 1972, but was abandoned due to excessive silting of the recorder well. There are insufficient records from the station for any form of station analysis.
