Fecal coliform data are not included because very
few bacteria colonies were counted during the study.
h
Staff time did not allow for analyzing TSS and
phosphorus samples for the last two sampling events in 2006.
h
The operations staff at Superior’s Environmental
Services Division recorded rainfall data with a rain gauge. Data were recorded in inches and then
converted to centimeters of measurable precipitation per day. Snowfall was also measured, and if rain
and snow were both measured on one day, these values were added to get
total precipitation.

Between October 4 and October 6, 2005, nearly 19
cm (7.5 in) of rain fell in a 25-year storm event that caused widespread
flooding in South Superior. One of
the drawbacks of manual sampling with limited staff and time was that we
cannot always measure the rapid changes in water quality that occur in
streams immediately after a storm event, so the data do not reflect the
direct impact of this rain event on the streams.
h
The extremely high precipitation event recorded for
February 24, 2006, is most likely a fluke.
Snowfall was measured at 17.8 inches and rain was measured at 0.5
inches. The snow most likely was
not packed down in the gauge, and air spaces between the snowflakes
inflated the measurement to an abnormal level.
