    I heard as of this last snowfall, they’re changing from a measurement format to a rating system instead. Now they’re trying to determine official terminology, with the options being, very deep, bloody deep, or f*#@ awesome deep.

    Havent seen any roofs off this year yet, maybe longer wind events than last year, But during the storms last year she really tossed it on. .. A lack of 5 day high events this year, front on front ina good wetsrely drift. that could be the difference.. You are a good windometer being out there nearly every day.

    Watch the Perisher app at 6.30am? they would already know.

    Does anyone know where the snow depth measures on Mt Perisher actually are? I have found 2 so far at other sites

    The snow drifts at Thredbo this year, have been unlike any other year I've seen before.

    By way of example, here is a photo from my bedroom window in Smiggins (about 1650m) from a couple of days ago. Two storey building...



    A drift or two of that sort of scale within the Snowy Hydro measuring course would provide for quite a remarkable official depth (even if some other of the measuring points within the course had been scoured down to a degree). There are BIG drifts this year.

    Nice!

    Definitely areas in the Lee of any obstacle have had big drifts. It has made for some good / interesting lines. Similarly high exposed areas have been very patchy!

    Whilst it has been a great season, I wonder if it has contributed to the bottom of Thredbo being better than I have ever experienced it (even earlier in the season)?

    Thanks for that

    We have a similar occurrence at our lodge
    Some of these windblown drifts were bigger than expected..

    Still waiting for the figure to be put up on the Snowy Hydro website but based upon 224.5 reported by @tomtankman and Perisher (claiming of course 225) - @BlueHue is this week’s winner with a very specific estimate of 225.13. @IAB and I were close, though!

    Why do Australians call it hydrogaphy? It is hydrology, hydrography is something related, but also quite different.

    Anyway, details? I know people that would be seriously interested, especially if the role has a snow hydrology component.

    I assume it is because it is what the role actually entails. eg A radiologist and radiographer are quite different but related roles.

    They are definitely looking for a hydrologist, not a hydrographer.

    The last couple of days have been very warm and there is no significant snowfall predicted between now and next Thursday so ... I’m guessing a net loss, with a figure of 217cm.

    209.55 is the answer to that question . With that in mind 225 for next week, we may make 240 for the season. we deserve too

    Wow, some of you are optimists! Predictions are for rain, a little snow, then some warmth over the next few days. I’m predicting a loss, with 201.5cm for next week. Happy to be proven wrong ...

    Spencers Creek not updated yet but Deep Creek is 98.1 cm and Three Mile Dam is 9.8 cm. A small drop at Deep Creek and a larger drop at Three Mile Dam reflecting the rain at lower elevations in the past week.

    I’m flummoxed as to how the snow pack at SC increased by 1.6cm when we had rain, warm weather, and no real snow to speak of over the past week!. My observations today at Perisher (when I could actually see anything) were of holes opening in vulnerable spots and increasing patches of vegetation around the place. Still plenty of snow in other areas, though.

    Me too. I reckon someone stuffed up!

    My prediction is a big hit this week, 166cm.

    Could be down to pure statistical impacts. Iirc they take samples across a wide area and average it out. They will be ok with variances within a tolerance as they’re after the long term info, don’t care about ‘the number ‘ like this forum does!

    I think its accurate. Some of tbose storms would have been wet snow up high with minimal rain and despite the high daytime temps weve had a few overnight freezes which has minimosed losses to date.

    I think there are 3 factors at play :
    1) Although the method is scientific, there is margin for error, probably +/- 5% or so. If they measured in the same spot on the same day they wouldn't get identical measurements
    2) It did snow above 1800m on the morning of the measurement (see @SMSkier pics of 8's he did on the perisher thread)
    3) The snow base is compacted and consolidated at this stage. The thick areas (eg 2m where they do the measurement) lose relatively little, even in poor conditions. Most of the snow loss occurs in the vulnerable spots, eg around rocks and trees, in thin areas, at the edge of the snowpack, areas close to flowing water (including under the snowpack). The melt happens from these areas most rapidly. By definitiion, the 2m area where they measure, is not at this stage one of those vulnerable areas

    So taking all of those things into account, I am not totally surprised by the result. Similar results have occurred in previous years

    Elevation played its part in the last weather event. Above about 1800 ASL depending on aspect had a net gain IMO.

    This is out in the range today in a relatively open location.....probe measures 2.5m plus the operational end. Pushed it in full distance and did not get to base - so 3 metres plus. Whilst it’s not at SC there is a massive amount of snow out there where it’s had the chance to build up. Not surprised that Spencer’s has good numbers.



    And here a nice shot at lower elevations, just for contrast...the thaw is well underway.

    Do you reckon there's more than last year? Spencers Creek peak was higher last year but my feeling from just tootling around the resort is that there's more snow this year.

    There are around 20 measurement sites in an area of around an acre. It's on a hill side above the creek itself. The reason for it's existence is so that the hydro have an idea of the inflows during spring.

    No idea why we saw an increase after a rain event. I'm guessing there's been some movement of the pack on the hill (it's not a steep hill, you can see it from the road to Charlottes)

    Really hard to say, seems pretty similar to me.

    I do have to say that depth isn't all it's made out to be.

    Not sure. Depends on ones memory and where your getting about. The winds have left lots of deep drifts and every season is obviously different. Plenty of cornices out on the range with some natural slippage. Saw heaps yesterday.

    In respect to that last weather event.... it was a net gain above about 1800 / 1850 ASL. You could see that up high. Different however at lower elevations where it was more of a loss. Current weather is impacting the snow pack.

    Isn't the measurement also about how much moisture is in the snow or something like this? Does that affect the reported number or just go into other data they use?

    Yep. Have spent quite a bit of time on the ridgeline above including Guthrie’s Trig back to the Charlottes end. Very likely to skin over there early this Thursday from PV with a few others on the forum (weather and conditions permitting). Will get a first hand look....
