Boat landings

Water and bottom

  • Bottom: 55% sand, 15% gravel, 25% rock, 5% muck
  • Kind of lake: a seepage lake: no stream in or out, it's fed by rain and groundwater

Invasive species

The DNR has found banded mystery snail, Chinese mystery snail and purple loosestrife here.

State law: before you leave the landing, pull off any plants and critters, drain all the water out of your boat, motor, livewell and buckets, and never move live fish away from the lake.
