Reduced inflows to dams

This graph shows how the average amount of water received into our dams has dropped dramatically in recent times. 

In order to provide an accurate comparison Stirling, Wokalup and Samson Brook Dams are not included in this data, as these Dams only came online in 2001.  Inflow is therefore simulated based on Perth dams pre 2001.

For total inflow which includes Stirling, Wokalup and Samson Brook Dams, please see the graph on the right hand link of this page.
