On August
11th and 12th 2005, the Menahga Conservation Club completed their first
citizen based mussel survey at the DNR Shell City Campground. Thursday
evening the group focused on learning what they could about the mussels they
would be searching for on Friday. The group received training about mussels
from Mike Davis, DNR Malacologist (Mussel Specialist). Mike did an
excellent job explaining about mussels and why they can be very interesting
to study. Mussel health is a concern because mussels are a good water
quality indicator and can be considered much like the "canary in the
coalmine". As the Club had adopted the Shell River in 2002, one
observation the group noted was that there were not as many live mussels as
people remembered.
Working with the DNR, the Rivers Council of MN and the Wadena Soil and Water
Conservation District, the group wanted to research why there might be a
change. The DNR had completed a mussel survey on the Shell River in
2000 through LCMR Funding but they only were able to survey a few key areas.
In working with Mike and Angie Becker-Kudelka from the Rivers Council of MN,
it was discussed that maybe a citizen group could be trained to survey for
mussels. Although no current network exists in Minnesota, a citizen
mussel watch group exists in Texas. In having completed the survey
this August, the Menahga Conservation Club gets the distinction of being the
first citizen based group in Minnesota to accomplish a survey.
As for the survey on Friday many empty shells were found along the campsite
and approximately 50 live mussels in a 45 minute, 12 person search.
One thought is that the mussels do not like the foot traffic from the
campers and canoes. This may explain why fewer were observed at the
campsite. A quick check at the bridge did result in quite a few live
finds but as the Menahga Conservation Club continues to learn about the
Shell River and its inhabitants, maybe answers will be found. As a
note, a special permit was needed to conduct this survey and one will be
needed in any future surveys.
