Just saw this on WaterCorporation www. click on Sources then Future
Last month I updated my Perth dams catchment rainfall and it is plain that Perth catchments rain is similar to levels of 40 odd years ago (May to Oct av now ~850mm). Will add more later on the 20+ years history of the WA Govt. avoidance of valuable rainwater that falls free from the sky. Every year on average 2,975GL of rain falls over Perth dam catchments and if catchment bush was managed so that only 5% of that water was harvested as dam inflows that would mean 148GL PA which is ~52% of Greater Perth annual consumption.
