Surface Trends
for West Upper Lake, Lake Minnetonka
The
RUSS data from West Upper Lake in Lake Minnetonka has been
summarized to show the average values of the measured parameters
in the lake's surface layer on each day.
NOTE:
Currently the RUSS unit is limited to an uppermost sampling
depth of about 0.7 meters. Typically, we will average values
for 1, 2, and 3 meters to calculate the mean "surface water" value.
The depth range was chosen based on examination of the mixed
layer depth from soon after ice-out through June 1998.
Also
available is a downloadable Excel
spreadsheet (it's about 130 Kbytes) that contains all of
the data and charts listed above.
These
data should be considered "provisional" until otherwise
indicated. The data are undergoing several rounds of QA/QC
review and some of the data may be modified at a subsequent
date. We chose to leave the data hose on full blast whenever
possible to familiarize ourselves with the operation and
maintenance requirements of the RUSS units and to generate
real data for use in developing curricula and lesson plans.
Data gaps were associated with various RUSS system upgrades
and occasional gremlins.
