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.
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.
Just ran an update as at 31 July – several Water Corporation stations look suspect – several BoM stations are out of date by months. My spreadsheet showing audit required.Source of BoM data and map – for a years daily data enter the 6 digit BoM station ID alongside Station number then click the Get Data button. Map showing dams and localities. BoM map with their sites and dams visible.
In May I reported – West Australian Govt Water Corporation fails to record March 2016 rain at several dams
The WA Govt would have wasted way more free rainwater than this by not managing Perth dam catchments over decades. Spud king Tony Galati’s firm faces water fines
Just noticed this classic water news from Perth – global HQ of the rain-denial-desalination-promotion movement. Water Corp plans waste water treatment expansion, increased desalination – not a word that the Perth region and catchments have enjoyed above average rain in 2016 and in each month except Feb.
Percent rain all Australia so far in May – Percent rain just WA so far in May.
Here is a rain history for Perth catchments – just the runoff season. Pretty good rain on average.
Time we are reminded about the very good Agritech Salinity Crisis Action Plan so highly ignored by WA Govts. The WayBack Machine still has the Agritech site from several years ago. Contact details are obsolete.
I also had a page up.
Agritech also had their Wellington Dam Water Recovery Project – also on the WayBack Machine. Too good a project for the WA Govt.
I have mentioned the Agritech Wellington Dam project more than once.

Digger falls into hole left by burst Adelaide water main on arterial road at Prospect 20 May 2016 – The Pulse NewsCorp Blog
This year I have noticed these headlines just keep on – can anybody find a timeline of all these water main bursts?
I am just amazed that a water utility can “unlearn” basic engineering good practice established over more than 150 years.
Today – 8 May 2016 – 19 Mar 2016
In percentage terms – plenty of rain across our north this month which is usually the start of the dry.
Some of the high rain areas on this map will be worth multi-$Millions in extra agricultural production. The plus 400% contour should be a bit wider east and SE of Darwin – where two outback stations scored +100mm on the 10th.
Check this out – Commonwealth environmental water – scroll down to the last chart – they are proud of buying and wasting 1000GigaLitres of water each year.
This water should be going into more efficient irrigation in the most productive parts of the Murray Darling Basin.
Earlier generations taxed themselves to construct nation building dams, Dartmouth, Eildon, Hume, Snowy – and we piss the water away into swamps and in the hope of keeping the Murray mouth open – it is truly disgusting. Election coming up – make sure you always put Greens last. Write to MP’s and let them know what you want to see done.
Here is a map of all rain stations in the Wellington Dam catchment – marked by the green line. You can make your own map at CDO –
Once you have the map scaled to where you want – if you left click on the station dots, a link to the daily data pops up.
Wellington Dam was built by the Commonwealth in 1933 and enlarged in 1956 – it has the largest catchment in the South West and the second largest in Western Australia at ~2,500 square kms (after Ord River Dam) – and is fed by the Collie River. Combined Perth water supply catchments are ~3,500 squ kms.
The rain data I obtained from the above map is summed up here.
Wellington Dam has salinity problems due to over clearing and the water is little utilized by anybody now – Harvey irrigators have at times used some of the water and I have asked for the time series of that usage and it has not been emailed to me. Over a decade ago the Agritech consortium developed a proposal to desalinate the saline (~3,000ppm solids) wastewater from the dam and supply this to the Perth water supply. Various Govt water Depts and quangos have fought this proposal tooth and nail for years with the tenacity of a starving rottweiler defending a leg of beef. Alternative Govt proposals have been floated over a decade to utilize Wellington Dam water but nothing has come to fruition that I am aware of. Wellington Dam has overflowed in 2005, 2007, 2009, 2013, 2014 – which should be embarrassing for the dog-in-the-manger WA Govt as much of this potentially useful water goes to waste. The Ancient Romans were better water managers than the WA Govt.
March 2016 rainfall has been checked for a group of sixteen BoM stations listed below and the nine rain stations of Water Corporation from their dam sites. Five of the nine dam sites of Water Corporation registered zero or negligible rain for March. This is obviously in error and is amazingly negligent for an organization that has been preaching about “our drying climate”, bleating on how stream flows have near stopped, while neglecting to manage catchments for over a decade. Several BoM sites are slow to record daily data. The several sites where the same names are used by BoM and WA Govt seem to be different stations.
