We are now collecting "real-time" data from Amity
Creek in Duluth, MN. Like the Stream Monitoring Units
(SMUs) at Chester, Tischer, and Kingsbury Creek, it is
sampling at 15 minute intervals for depth, flow, temperature.
conductivity, and turbidity. This SMU uses newer technology
-- allowing us to update the website 3 times a day. The
data from the other streams is usually updated once daily
(generally by 10 AM).
Kingsbury Creek is
still limping along. First it was hit by lightning this summer
and now the data transmission phone line was damaged during
some construction activity. Fortunately, it is still logging
data although there is a delay in posting the data.
You can use our Java-based
Data Visualization applet to explore the data from
the SMUs and create plots like the one above. Weekly data
files from Amity Creek can be found

The Kingsbury Creek sensors are
still out of commission, apparently from a power surge during the
evening thunderstorm on 6/28/05.
