3.3.3.1 Rainfall Data
Rainfall data for the site was chosen to give the best representation of actual conditions. A time period of
10 years between 1973 and 1983 was selected from the Cooroy Composite station, using a six minute time
step. The Mean Annual Rainfall for this period is 1595mm, and the Mean Annual ET is 1201mm. See
attached Appendix B for details.
