Perth dams rain data 2016

I am surprised the BoM and the WA Govt Water Corporation have not got their Perth dams rain data in order at the end of 2016. I have several posts on the subject through 2016 and have called for an audit. The latest was WA Water Corporation can not replace a couple of rain gauges in 2 months 27 Oct 2016

Australian Government financial disasters

I will add to this list and links as ideas come in. We may be the lucky country but surely stupidity will extract a price one day. All these issues would make articles in their own right.

[2] $6Bn Collins Class Submarines 1990’s – duds we are still stuck with,
[3] Electricity privatisations started in 1990’s – looking at our ballooning power prices would we have been better off keeping the old State Electricity Commissions? Despite the feather-bedded unions.
[4] MRET scheme making 3 worse and harming our electricity grid into the bargain – ongoing multi $Bn’s as taxpayers fund wind & solar that can never power our 24/7 grid,
[5] Defence purchases eg MRH-90 helicopters $4.2Bn,
[6] Frequently delayed and poorly performing F-35 fighters $24Bn alone,
[7] Eastern States Desalination plants ~$20Bn,
[8] Rudd Labor watering down border laws $11.6 billion over five years,
[9] Decades of anti-damism – after not building the Franklin Dam in the 80’s,
[10] Antifracking hysteria affecting gas exploration policy in face of rising prices,
[11] Building the Education Revolution $16.2Bn – More money for Education = worse results,
[12] Adelaide Hospital third most expensive building in the world $2.1Bn,
[13] Inability to control rogue unions like CFMEU which affects 12 and all other construction est +$10Bn,
[14] NBN a future $100Bn mediocre performer?
[15] Buying 12 French submarines before even a prototype is built future $50Bn,

Please send in useful links and analysis. I must have been half asleep to leave the Rudd MkI Pink Batts and School Halls stimulus projects off the list. Also forgot to add GreenLabor’s Murray Darling Basin Plan to waste more dam water to the ocean.

South Australian Minister for Water expresses their Murray Darling Basin policy succinctly

SA MP reined in after ‘F*** you all’ comments over Murray-Darling Basin Plan – slapped on wrist with a bit of cooked lettuce.
All the Crow Eaters want is for the Murray Darling water to run into South Australia unimpeded – then they will do what they want with it – simple.
Imagine the meedja hysteria if a non-Left pollie had said these things.
We expect our politicians to speak robustly but his reported references to women surely make him unsuitable for cabinet office.
NSW and Vic should cut down on environmental flows and use the water as they see fit – then let what is left drain into the failed State of South Australia.

WA Water Corporation can not replace a couple of rain gauges in 2 months

I first saw the notice under the Table at this Water Corporation page on 26 August “rainfall instruments located at Victoria Dam and Mundaring Weir are being serviced and are not currently recording rainfall.” – there was no such notice on 1st August. I emailed the WA Minister for Water on 9 August Subject: “Audit required Perth dams rainfall”.
The Water Corporation notice has not changed in 2 months.
A Water Corporation staffer could have bought a couple of $10 rain gauges at Bunnings – plus a couple of star pickets and in the space of a few hours have functioning rain gauges again at the Mundaring & Victoria dam sites.
It simply beggars belief that in more than 60 days they still say the sites are “…being serviced and are not currently recording rainfall.”

Proof WA Water Corporation does not reliably record rain

After a wet weekend 15th-16th October WA Water Corporation recorded rain at only 2 of their 7 Perth dam rain stations on Monday morning the 17th.
You can check the widespread rain around Perth on 15th and 16th of October just click the Perth region on this AWN map and scroll down noting rain on that weekend.
Now the WA Water Corporation records rain 5 days a week at their dams at this page. I have kept many daily screen shots over several months and often the recording of daily rain by Water Corporation bears little resemblance to rain that we know fell in the district on the preceding day. So clearly the proviso at the bottom of their page about “rangers may not collect rainfall readings daily” is very very true.
In the case we are looking at – the widespread rain on 15th-16th Oct – for 5 of the 7 dam rain stations no rain data was collected up to 6 & 7 days later. Obviously with delays taking rain readings factors like evaporation could make readings less useful with every day that passes – but a week!! If they use electric gauges then they are subject to errors too. I do not know what goes on in Water Corporation but it is imperative that all of their daily rain data be made public so anybody can check how their taxes are being spent.

Obfuscating reply from WA Minister for Water re my call for rainfall audit


My emails asking for an audit are in comments.
My Table below from 15 Sep – of catchment stations with 2016 rain totals updated through August shows that the Mundaring Weir/Dam, Victoria Dam, Churchmans Brook, Serpentine Main Dam and Wungong Dam rain data all show many examples of disparate monthly totals that require an audit.

BoM Outlook for September predicted average zone rain for flooded areas of western Victoria

There have been misleading comments on TV news implying that BoM rain Outlooks predicted the heavy September rain in western Victoria that has caused flooding around Coleraine and Hamilton. This is not so as is shown on the September rain Outlook map below.

In the flooded zones the prediction was for 50-55% chance of exceeding the median rain.

Perth dam catchments rainfall – how much is that?

It is obvious that BoM and Water Corporation rain stations are low down in catchments near the various dams –

convenient near roads and easy for staff to monitor. Click on Select Using Map – Large areas of the catchments are not monitored by BoM rainfall stations. In 1997 this contour map showed annual average rain for SW WA – the rain numbers would have been heavily influenced by pre 1975 higher level rainfall. It would be helpful if the WA Govt or BoM could redo the map using post-1975 rainfall – which is vastly more relevant to water supply issues than pining after pre-1975 numbers.
The WA Dept of Food & Agriculture have a www site for their own network of weather stations – which in many cases also report to the BoM pages – for example the daily rain maps.
Last week I noticed that the DAFWA station Glen Eagle near the Albany Highway between the Canning and Wungong catchments has recorded the stunning total of 1280mm for the year to date.

Perhaps it is at a higher altitude – will try and find out. GE only commenced in August 2015 – I assume DAFWA checks the calibration of their instruments.
Here is my table of catchment stations with 2016 rain totals updated through August.

The zeros & blanks need urgent attention from the BoM and some monthly totals from Water Corp need examination.
The WA Dept of Water has a large network of stations in the catchments but most seem to be discontinued. Here is a map of their stations – Set Site Category to Meteorological.

I checked a string along the Brookton Highway and none was current – it is time consuming to check. Who knows what useful data they may have. We need all data public to audit and produce a better record of catchment rain.
