1.5.1.1.4 Gauged inflows in the Macquarie-Tuggerah lakes basin

Inflows to the Macquarie-Tuggerah lakes basin are recorded at four gauging stations on Ourimbah Creek, Jigadee Creek, Wyong River and its tributary Jilliby Creek (Figure 3). Annual streamflow for these gauging stations is presented in Table 7. There existed a large interannual variability in the annual inflow for 2004–2005 to 2011–2012. Mean annual inflow for 2004–05 to 2011–12 was 89 GL/year.
