Large gaps of missing data in 1990, 1991
The water temperature probe was replaced, and moved slightly on 11 Oct 2000@1300.
The probe had been out of the water, so a probe of the same type (CS 107L/thermistor)
with a longer lead was installed deeper in the pool (The pool level continued to drop
after the winters of 1996&1997).
The 1/2 hr temp. records end on 12/06/00@1900. When the PG3 was replaced with
the PAT the new program did not include the 1/2hr output.

Notes: The location of the water temperature probe was changed on 17 May 2001@0820.
It was moved upstream, above the gaging station, and further under the
forest canopy. The probe was moved because it was being affected by
the canopy opening of the parking area. During late summer in the middle
of the day, the temps taken at the probe were higher than those taken slightly
upstream under the canopy due to direct sunlight. During the winter in the morning hours,
temperatures were colder at the probe due to the lack of thermal cover.
A new probe number (Probe 02) is assigned to water temperature measurement
at this site for the new location, which has a very different measurement environment.
Probe 01 is discontinued.
