From a Western Australian Govt report emailed me – Water Innovation. I have not located it online but could be related to this bumph.
Facts are that rainfall over the Perth-Peel urban areas, the catchment areas for the Gnangara and Jandakot Mounds, plus the Perth Hills water supply dams & and Wellington Dam catchments; would average over 7,000GL of free water from the sky per year.
Having said that, it is strongly recommended to take only that much quantity as prescribed. So, stop smoking to increase viagra price semen count.

This drug works on heart is good news but it can’t cure the disease from the root, and they have to pay the money once they get their hands on viagra 20mg in india heritageihc.com the best possible deal is discussed. This absolutely dwarfs any other water on their diagram as the Perth water supply totals about 4% of rain. The efforts of the WA Govt water authorities over decades have been to ignore the benefits of dam catchments management and to allow Perth dams to be effectively decommissioned, while taking Perth water supply to expensive seawater desalination. The Ancient Romans were far better water managers.
We need an audit of WA Govt dam catchments rain data.
Now here is one for your records
Melbourne Water has graphs on its website dating back to 1904 showing how much water has flowed into its dams in the past and the state of its water storages, up to the present day. The graphs are computer generated and tell a vastly different story than is the reality.
What MW has done is include the Thomson Dam in its graphs at 100% full right back until 1904. But the Thomson Dam was only built during the late 1970’s and was first full in about 1980/81,(full being 80% as per recommended to provide a buffer). The Thomson Dam holds more water than all the pre-existing dams combined. As you can imagine the inclusion of the non existent Thomson Dam in the past figures at 100%, totally distorts the graphs so it looks like we have less water now, than in the past, giving the current regime collateral to argue that we need the desalination plant .
Inflow over the years. Note that there is more inflow prior to the Thomson Dam being built.[url=http://www.melbournewater.com.au/waterdata/waterstorages/Pages/Inflow-over-the-years.aspx]link[/url]
Storages over the years. Note how much water was supposedly in storage around 1950 before the Thomson was built .[url=http://www.melbournewater.com.au/waterdata/waterstorages/Pages/Storages-over-the-years.aspx]link[/url]
Is there any possibility that you could run this as a story on your website with the graphs shown? It would make for a salutary reminder to be wary of what the authorities are telling us about our storages.
Many thanks, I enjoy reading your site.
Here are some diagrams of the water cycle
