Example of error in Bureau of Meteorology rain data

On the weekend I noticed this error in the BoM rain map –

I thought come Monday they will correct this to 9.27mm. Here we are Tuesday and no such luck, the error has gone into their daily rain numbers – presumably to be discovered in checks at a later date, weeks months away. It has also gone into 3rd party sites like AWN

there could be others. It puzzles me that an error as gross as this lives on for 3 days – surely a little robot algorithm could flag outliers way less than this. I thought it was topical in view of my call for an audit of Perth dam catchments rain data.

Melbourne Water amazing wasteful environmental flows when storages were low 2007-2011

“mem” has commented on information at the Melbourne Water web pages – inflows and storages. Using their csv file from the storage page I made this chart.

In March I blogged – Victorian Labor Govt moves to turn on the Wonthaggi seawater desalination plant – see my chart of Thomson Dam environmental flows –

I am short of time to add much until about 6 Sept – but can do quick blog housework.

Is this the worst ever pictorial of the water supply cycle?

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.

Perth dams rain data is in need of an audit

Just ran an update as at 31 July – several Water Corporation stations look suspect – several BoM stations are out of date by months.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

West Australian water authorities do not talk about above average rain falling free from the sky

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.

Plans to reduce WA wheatbelt salinity and utilize Wellington Dam

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.

What is it with the series of burst water mains in Adelaide?


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.

Australian Govt wastes $Millions to make swamps a bit wetter

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.
