    Must have snowed a lot that season, because it looks like they had a couple of times where they lost 40cm very quickly, presumably rain events, and they still got to nearly 300cm:D

    Predicted dry winter might mean less snow, but also less rain...

    Hopefully 64 will keep being copied . 68 peaked late

    So when there is no data from snowy Hydro PB and CP just make up the figure of 60 cm. Now the data is in at 71 cm and they still think it's 60. They are too lazy or indifferent to set up a gauge in their own backyard at lower, middle and upper levels to give the punters an honest reading.... W

    This argument has been done to death. The snowy hydro reading is far more scientific than any single point depth measurement done by most ski resorts. SH measure 10 points over a set area in a reliable and reproducible way, that is completely unbiased and not influenced by the resorts, or their media people. In addition there is over 50 years worth of data to reference to. It gives a very accurate picture of the condition of the NSW snowpack

    Any single depth measurement in a resort is inherently unreliable. You could move 50m and get a completely different result.

    Measurements of recent snowfall are a different matter, and the NSW resorts should improve their game in that regard.

    Yes thank goodness we have the snowy data as the only reliable format for long term trends. Yes snow depth is important but so is snow quality , which at times in June /July has been awesome. Ok I thought we might have exceeded the 2000 Spencer's depth by QBW But the second front this week never materialised . Having said that the base of snow and quality down low was far superior in late May 2000 as I recall laps if Thredbo too to bottom then

    14.2 cm at 3 Mile dam. That'll be all gone if this next event gives the 15 mm of r**n for Monday plus 25mm on Thurs on BoM Cabramurra 7 dayer. And 14.2 is only half what was there mid June in 2018..... W

    Only got to look at the sat pics picks from Nasa. Alot of the snow in northern kosci is gone already im talking towards the Brindies they didnt seem to get much at all in the last two events.

    My take on some recent research is that Spencers Creek is not necessarily very representative of anything happening outside that specific catchment.

    I increasingly suspect it's regarded as commercial in confidence market sensitive data in the immediate period. they adjust future positions and squeeze a little more profit out of Snowy Hydro. Otherwise, if not, they should smarten up and get the data posted on time.

    Still no update from Snowy Hydro. Perhaps there’s nothing left to measure :D

    Yeah, being part of a hydroelectric scheme, that also shunts water off to rivers out west (occas. East) will do that.

    Stuffs up the trout fishing too. :)

    edit. If anything, SHydro must be listening. The little white line has bottomed. But curiously, is a future date? Naaah.. it is the 2018 position. Lower than now. I've added a second image showing current levels. Updated.

    Thredbo and Perisher have both updated their depths to 32(.1)cm, so id say thats this week's measurement

    Looking at the cams I’s say that's very generous - esp for Thredbo.

    Mind you, thats still much better than Vic.
    I’m not sure If I’ve ever seen 90 cm snowfall (Hoth/Falls) and a 45-50cm cover turn to <10cm so quickly! Thats since 85’?

    Maybe Sept. 95? Where great Aug. Cover was decimated by numerous pineapple hand grenades and days in mid 20s!!
    Scary & sad stuff.

    Oh We shouldn't be too hard on Perisher’s fresh snowfall measurement & reporting practices. Whats wrong with a std Gatorade bottle measure I say?? ( ;-)

    The current situation around perisher is typical of why it is hard to give a single accurate depth measurement. There are patches of bare grass, and 20m away there are areas that are 50cm thick. I am sure the spencers reading would have been the same, but averaged out to 33cm over the samples.

    Just for clarity, Perisher resort never posts pictures of gatorade bottles in the snow etc. The infamous “deptho”, is nothing to do with the resort. They are posted by mid-station on their FB page. Mid station is a privately run operation, not owned or run by the resort.

    Take a read of this: https://onlinelibrary.wiley.com/doi/abs/10.1002/hyp.13435
    Spatial controls on the distribution and dynamics of a marginal snowpack in the Australian Alps
    (and anyone else who is "into" Spencer's Creek)

    I can only see the abstract, the rest requires payment or login.

    I am well aware that spencers creek is not perfect. However, they do measure over 10 points in the selected area and averaged. IMHO this has to be more accurate measure than a single point measurement, as done by most resorts.

    For me it works well, I know exactly what a particular spencers measurement will equate to in various parts of the Perisher resort.

    Without doubt, the best representation of snow depth within a resort would be the snowsat system by Pisten Bully. I don’t think this is used at all in Oz, mainly in Europe. Even where it is used I am sure the measurements are “in house” only. https://www.snowsat.com/fileadmin/c...8_download/pistenbully_snowsat_09_2014_en.pdf

    If we want to get technical - add in a "how much snow is required to ski a given area". This also varies wildly. 5cm on a grassy groomer to over 1.5m in a boulder field. SPencers creek works very well because over time you start to be able to correlate that measurement to skiabily of various parts of the mountains.

    Deep creek holding strong at 12.4cm

    Just waiting for Spencer now.

    My guess 29cm

    As has Thredbo.

    Where in the world did Spencers get a 5cm gain? They must have had some good drifts from that dusting the other night!

    Maybe it was better falls up that way. But main SH depth chart remains as usual late to updated. Maybe some needs to remind the CEO that he hasn't sold it off to Singapore yet and he still works for the taxpayer.

    Snowy hydro has not updated their website, but Perisher are now reporting 39.9cm, presumably from the snowy hydros spencers reading. A slight increase from 37.1cm. About what I was expecting, given the snowfall over the weekend

    Good to see it creeping back up. This year the resorts have typically updated their depths a day before the results have been added to the offical site, obviously they have a direct communication channel of some sort.

    53.9cm at Spencer's Creek this week. Deep Creek is at 17.15cm and even Three Mile Dam has some runs on the board at 6.25cm after a number of weeks at 0cm. So last weeks system looks to have had a modest net gain in the measuring sites.

    Astonishing depth at SC given the lazy systems that have contributed since the start of June.

    Very cold nights and short days lately. Best snow making Year for a while.
    My guess is that the snow temperature is so cold from overnight that it takes ages for it to heat up to above zero so then it can actually start melting.

    What's the warmest day temp we've had recently?

    Plenty of westerly wind on the weekend to blow it in to lee aspects and the cold temps since the rain event sure helps.

    Not only short days, but because we are near the solstice the sun is low in the sky, even in the middle of the day, so much less solar strength.

    Is there a Snow depth prediction thread? Can’t find... anyway the next 3 Thursday promise to be action packed based on the current forecasts.

    I’m going for the following at SC with similar trend (% based) across the other locations:
    - 11/7 - 70cm
    - 18/7 - 120cm
    - 25/7 - 150cm

    In previous years I've been on the forum, it has been this thread that has been used for both predictions and reports of the offical snow depths that are recorded.

    I'm happy to throw another prediction in for this week - 59cm

    Looks like it was read today, 44.8cm down from 53.9cm. Good that they measured today, so we can see the difference next week, hopefully after a solid week of pukage:)

    Spencers Ck elevation 1830 m dated 9/7 is 44.8 cm
    Deep Ck - 1600m 10/7 is 10.16 cm
    3 Mile Dam - 1500m 9/7 is 0.0 cm
    Yes, fortuitous that readings done before the dump. If you add Jane's prediction of 100 cm in the next week to Spencers then we are nearly at Gerg's season 2019 max of 150 cm. Time will tell...W

    Since when did they start measuring on Tuesday’s?! The last 2 readings were 2nd and 9th... guess I’ll have to update my predictions:

    - next week: 120cm
    - following week: 150cm
