Graph of the Day: Total Annual Inflow to Perth Dams, 1911-2012

(Before It's News)

Desdemona Despair

This graph shows how the average amount of water received into Perth 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.

Year is taken as May to April and labeled year is start (winter) of year.
