Lake Mildred Quality Watch & Invasives
7/29/15 --- Connie Muckelberg (LMPOA Director) Reports on
A Day on the Water with AIS (Aquatic Invasive Species) Coordinator Michelle Sardauskas

          We observed an emergence of White Water Lilies as well as Water Shield that had not been in our area before the high water level returned.
         Along the East shoreline we were excited to discover Cadisfly casings.  Both of the samples had larva in them.  They were returned to the water.  The Cadisfly case looks like rough concrete with bits of sand and tiny pebbles embedded.  The larva, in a small space beneath, was about ½" long and as thick as the lead from a fine lead pencil.  They hatch to be small moths with hairy wings.  Their presence is an indicator of clear water.
          In the bay just East of the Stokstads we stopped and took several water samples.  Stephanie suspected blue Green algae.  The samples were analyzed and found to be just fine.
        The big news is that Lake Mildred has its first Invasive Species.  We detected the presence of the Chinese Mystery Snail.  These snails are often quite large - up to 3" tall.  They are greenish brown. They were actually discovered in Lake Mildred in 2011.  The DNR does not know who reported them, but we had not heard about them until this event.  Their impact on our native species is negligible.  They can carry a parasite, but do so rarely.  Manual removal of the Chinese mystery snails is the only effective method of control.  The snails prefer murky, organic sediments.  Watch for them and  please remove them.
          Stephanie congratulated the association as well as the residents of Lake Mildred for maintaining a natural shoreline and respecting the setbacks which provide habitat for so many tiny lives.
        It was a short but very productive day.

Some vegetation die off due to high water

In association with the DNR's "Clean Boats - Clean Waters" program, the Lake Mildred Property Owners Association and local boy scouts are working to keep Lake Mildred free of the invasive plant and animal species that are spreading to many other waters.  These so-called "Invasive Species" can take over a lake and irreversibly damage the lake's ecosystem.

Beginning with the July 4th (2005) holiday weekend, local boy scouts and association members began working together to take turns at the boat landing, meeting people who were landing their boats, to look for weeds or signs of other invasive species on their boat or trailer, to take a short survey and to inform the boat owners about the spread of invasive species.  We have found that both association members and boaters are enthusiastic about the idea of keeping Lake Mildred "pure" and clean.  Above is a photo of a few of the people helping out at the boat landing (L to R, Dave Ebben, scout John Schmitz, Dave Schmitz, and scout name?)
Slow the spread of aquatic invasive species to lakes, rivers and wetlands

The primary way aquatic invasive species spread to new waters is often through the very people who most enjoy those waters. Zebra mussels and Eurasian watermilfoil actually hitch a ride on boats and trailers and in livewells, traveling from one lake to another. It is illegal for anybody to launch a boat with zebra mussels or aquatic plants attached.
To prevent accidentally transporting invasive species:
  • INSPECT your boat, trailer and equipment and REMOVE visible aquatic plants, animals and mud before leaving the water access area.
  • DRAIN water from livewells, bilge, motor, bait buckets and transom wells before leaving the access area.
  • Empty bait buckets into the trash.
  • DRY the boat and equipment for at least five days before transferring to a new lake. If drying isn't possible, RINSE boat, tackle, downriggers and trailers with hot (above 104 degrees F) and/or SPRAY with high-pressure water.
  • Learn what invasive organisms look like. REPORT questionable species to your local DNR service center for identification assistance; preserved specimens are needed to confirm sightings.

DNR representative Mark Stokstad showed us how to check for invasive species on boats and trailers at the Lake Mildred boat landing.  We also learned how to inform people at the landing about the danger of invasive species, and to ask a few questions about where their boat had been previously and if they knew the importance of cleaning off the boat and trailer every time they launch.  

Since then, some local boy scouts and association members have volunteered to take turns at the boat landing, talking to the people coming and going, looking at their boats, and just trying to be helpful and informative about the invasive species that are spreading all over the state.
