Figure 6-18 The Effect of an 80 th Percentile 30% Access Licence Condition on Secure
Yield
From this analysis it is concluded that alteration to the current licence conditions to formally
incorporate low flow and percentage of total flow protection will reduce the ability of the
existing system of source infrastructure to supply demands in the future. To meet this
source infrastructure shortfall, water conservation and supply development strategies are
outlined in subsequent chapters. These measures together will maintain security of supply
during drought while catering for population growth and development.
