RE: Status of Southern Sierra.
The Kern is expected to crest on June 24 at 75 [flow measurement] but drop
to 55
by 4th of July. During the next two weeks even the smallest stream may be a
challenge at the snow melts
on the western edge of the sierra crest.
Currently, the average snow [as water content, double for average snow
depth] is 21" at 10,300-10,400 and
37" at 11,200-11,500 and is melting at the rate of 1" per day. Snow below
9,500' is melting faster. Everything below 8,000'
has largely melted.
What this means is that anyone traveling north from Kennedy Meadows is
walking into a relatively low zone that may appear normal but travel north
out of the Kern Dranage may require serious snow skills.
Long term:
Assuming that the 10,300 elevation will be melted in 21 days [July 9] and
the 11,400 elevation will be melted in 37 days
[July 25], it is not rocket science to predict that the 12,000' elevation
will melt approximately 53 days from now or about Aug 11.
Obviously a melt faster than 1" day will change that.
Note: These predictions are based on several sources. Use them at your own
risk. For 10,000' data I use Charlotte Lake and Chaooga Plateu. For 11,000'
data I use Upper Tyndall Creek and Bishop Pass.
