On behalf of the Mirror Lake Association and Mirror Lake Management District
Welcome to Mirror Lake!
The Mirror Lake Association is a non-profit organization created in 1986 to protect and help maintain Mirror Lake as a natural area that people can come to and escape the commercial surroundings of our world today. The Mirror Lake Management District is a local government created in 2006 with taxing authority that raises funds and administers grants that protect, rehabilitate and enhance Mirror Lake.  These two organizations work together with many other partners on the lake to make it a peaceful and relaxing recreational destination.
We wish you a great day at Mirror Lake!

MLMD is a local government under Chapter 33 of the Wisconsin Statutes. It has the authority to tax property owners within its boundaries, limited annually to $2.50 per $1,000 of assessed value, excluding special assessments and special charges.  MLMD can receive charitable donations as well as apply for grants from the DNR and other organizations that often require a 25% match in dollars or volunteered services.  As a government entity it’s liability is limited, making it possible to insure high risk equipment used on the lake such as weed harvesters, pontoons and boats.  It is not allowed to save money for future projects.  However, it can set aside funds to repair or replace capital equipment such as weed harvesters. Some of the projects MLMD is involved in include:
  • Own, insure and hire employees to operate equipment on the lake
