Just Past Peak Upper Elevation Snowpack

The statewide snowpack water equivalent, based on an average of all stations in Utah, peaked on April 1-2 at 18.8 inches and after fluctuating just below that value for about 10 days, has been steadily declining and now sits at 15 inches.

The peak of 18.8 inches was 117.5% of the median peak of 16 inches, so it's been a decent snow year statewide.

The situation though varies depending on region and elevation.  We'll focus here on the Wasatch Range.  The lowest elevation SNOTEL site in the Wasatch is Ben Lomond Trail in the North Ogden Valley, which is at 5971 ft.  The snowpack at Ben Lomond Trail also peaked on April 1–2.  This is a snowy location, so the peak snowpack water equivalent was 28.4", more than 10" higher than the state average, despite the low elevation.

After April 8, the snowmelt at this site began in earnest and it has since shed a bit more than 10" of water, or a bit over a third of the snowpack.  

Above this site at the Ben Lomond Peak SNOTEL site, which is at 7688 ft, the snowpack peaked at 53.4" where it sat at from April 8–11.  It has declined only slightly since.

Here, energy from the sun and atmosphere in recent days have been warming the snowpack, but have not warmed the snowpack enough to produce much meltwater.  At this point, I suspect the snowpack at this location and elevation is close to "ripe" or near 0°C through its entire depth, so continued warm sunny days will likely yield a more rapid loss of snowpack.  

In the central Wasatch, the snowpack at the Parley's Summit SNOTEL at 7584 ft, however, is ripe and has been releasing meltwater.  Snowpack water equivalent has dropped from 19.2" on April 10 to 12.5" yesterday.  In a few days, the snowpack at this site will be about 50% of peak.

The Snowbird SNOTEL at 9177 ft looks a lot like Ben Lomond Peak.  It maxed at 48.6" from April 8–13 and has declined just a smidge.  Here too energy from the sun and atmosphere have been warming the snowpack but have not warmed it enough to release meltwater.  Note that due to high elevation and a northern aspect, the median peak for snowpack at this site is actually in late April.

Given that forecasts look pretty dry for at least the next few days and mild to warm, I suspect it is safe to say that we are well past peak snowpack now in the mid elevations, are probably past peak on upper elevation south aspects, and are likely past peak on upper elevation north aspects.  

It's a shame we can't save about half of this snow for next season.
