The fall stream
monitoring took place
September 20 on Jordan
River for macro
invertebrates
(bugs). The testing was
done at two river
locations and samples of
the bug population were
taken. By looking at the
number and diversity of
the bugs found can help
determine the health of
the river. When
pollution problems start
up in a river it affects
the macro invertebrates
far sooner that anything
else. By keeping track
of the bugs we can spot
a pollution problem long
before you ever see the
first dead fish.
The Jordan has now been
monitored for two full
years at two sites. The
diversity of bugs has
been high at both
Webster Road and Fair
Road sites, earning us a
grade A rating. The high
quality waters of the
Jordan are due to little
development and human
activity along the
river. The river has a
great diversity of macro
invertebrates with
impressively high
numbers of sensitive
families.
Volunteers get samples
out of the river by
scooping from under
vegetation, logs, and
gravel, and bring them
on the shore where
others look for the
bugs. The bugs are
placed in jars of
alcohol. Weather and
other data are collected
before moving on to the
second site. Then in a
couple of weeks the bugs
are examined under
microscopes where they
are sorted, categorized,
and counted. This is
done at NCMC college
science building in
Petoskey.
We always are looking
for volunteers to help
us with the study. And
it's a great activity
for kids to learn about
the river and how to
take care of our
environment. If you are
