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.
There are lots of other factors to consider. Water content of the snow for one. How fast this snow is going to melt is another.
The combination of a reservoir pool with more water than last year and well above average, plus a good amount of snow in the high county points to some high flows this spring and early summer in the South Fork Boise below Anderson Ranch.
