We are dedicated to protecting the pristine water of Walloon Lake that we all know and love.

Below are few of our primary water initiatives:


In partnership and collaboration with Tip of the Mitt Watershed Council, we keep tabs on the biological and chemical components in Walloon Lake. Volunteers take weekly water quality measurements including temperature, pH, and clarity. We have been collecting these same measurements for decades and compare the data annually. This allows us to closely monitor any changes and mitigate their negative impacts.


A key part of our water protection is aquatic invasive surveying and treatment. By doing so, we prevent dangerous infestations which can quickly overtake the lake. Each year we contract specialists to locate and eradicate new or common invasive species. The funding for this important work is provided by our dedicated members.



Below is what YOU can do to help protect the water: 


Make sure to wash your boat(s) before launching them into the lake to prevent the transferring of water or plant materials from other locations into Walloon. We host multiple free boat washing events throughout the summer season (June-August) at Jone’s Landing – located on the North Arm. 

Boat Washing


A typical septic system will last for 20-30 years but requires regular pump outs and maintenance. An unmonitored or failing system will leak septic into the lake. Please review this report on how to maintain your septic system for both your health and the health of the lake.    


What is a greenbelt? An area of plants, such as native flowers, shrubs, and trees, planted between your lawn and the water. These natural shorelines protect the lake from detrimental runoff, including pesticides from lawn maintenance and drainage from driveways/roads. 

As more land around the lake is cleared and developed, there are fewer opportunities for rainwater and other precipitation to be absorbed by the soil and filtered before entering the lake. To help, don’t mow to the water’s edge and plant a greenbelt to help improve water quality. For more information explore the resources below or contact Tip of the Mitt Watershed Council for advice:

Sensible Shoreline Development

Natural Shoreline for Inland Lakes


Swimmer’s Itch is caused by a parasite which lives in all northern Michigan lakes. The parasite cycles between snails in the water and ducks (often Mergansers or Canada geese). The characteristic rash lasts 3-5 days and is itchy and uncomfortable. There are a variety of creams and treatments available to ‘prevent’ swimmers itch, but none has proven effective for every case. Some lucky people are naturally resistant, and some may find one type of cream works well, while others continue to get Swimmer’s Itch. 

To reduce your chances of swimmer’s itch:

  • Establish a greenbelt of natural shoreline plantings to discourage ducks and geese from nesting on your property as Swimmer’s Itch is most prevalent where waterfowl congregate.  
  • Head to deeper water. Shallow, warmer water is more likely to bring you into contact with Swimmers Itch.  
  • Towel off or shower when coming out of the lake.
  • Consider one of the swimmer’s itch ‘remedies’ available for purchase.

Please report cases of Swimmer’s Itch to our office by completing this form. We are tracking incidences and participating in scientific studies about the causes and possible prevention.
