I measured a core in 12" of snow and got 2.1" water. Using 40% bare ground, I converted this to 1.3" water equivalent average. Dont know how else to do this!

2/22/2010 6:00 PM 0.05 0.6 0.05 15.0 2.80 The SWE is an estimate. I measured a patch of the deepest snow and got 3.4" water. Figuring my snowpack is very patchy (estimated 40% bare ground before the latest storm), so snowpack is very uneven. I reduced the 3.4 to an average of 2.8 so my figure is an estimate.
