I received this email this morning from someone with years---decades---of experience in the Panamints,
"Harold: We had developed a water pickup at the conjuncture of three
springs at about 500 ft above our camp, and in the canyon to the north,
which we referred to as Sentinel Canyon. We never experienced a
decrease
in our water flow. The water line was 1/2 inch and we got 4 gallon per
minute.
In 1998, after returning from a trip to Texas, we discovered that a
cloudburst had occurred near our water pickup point and filled our line
with mud, which had dried. We then located our pickup point well below
the
original one, because the vegetation between the two points was so
dense
that we couldnt retrieve the line. The water flow was ok, still 4 gal.
With the arrival of summer, the flow dropped to practically nothing,
because of evaporation. We then acquired a significant length of 3/4
line
, packed it in and repositioned our water pickup further up the canyon
were the flow from the three springs came to a point. Our flow
increased
to 10 gal per minute which fell proportionate with the increase in
temperature, but not less than 6 gal per minute. We were quite pleased
with that, and because of the increase flow, we didn't have to cover
the
line as much at a point where the line made a turn and didn't see the
sun
from Nov to March."
