It certainly was a long, bleak December and early January, especially if you ski at Bogus Basin. The drive into the South Fork canyon was less treacherous. In the past few days a wave of Pacific storms finally arrived and dumped snow across western and central Idaho. Here’s a chart showing snowpack so far this year compared to the three previous years:
So what does this mean for flows this summer?
It’s the 20th of June, almost summer. There is more water (frozen) at the Trinity Mountain snow site than there ever was in 2010.
Lots of Snow at Trinity Mountain
The snowpack at the Trinity Mountain site is well above levels seen the past two years. It is running about 125 percent of average for this site, both for total precipitation since October 1, 2010 as well as snow water equivalent snowpack.
The last post reported on the water stacking up in Anderson Ranch Reservoir. Here’s a snapshot of the snow in the headwaters, at least at one station. Trinity Mountain seems one of the more important sources of water for the South Fork Boise River. Here’s a comparison chart of the 2009 snow compared with 2010, and then another chart that overlays the 2011 snow depth accumulated so far.
