Harvesting/Aquatic Plant Update

A situation that may affect some shorelines is that harvester operators must maintain a minimum of 10' clearance of any and all personal property, such as piers, boats/boatlifts, swim platforms, canoes and kayaks.  This is a safety policy to reduce any possible damage that may occur from the harvester being veered off course due to weather conditions, boat wakes, etc.

You, as a resident do have the right cut and gather vegetation around your property to keep your area clear.  The DNR has issued Eagle Spring Lake with a 'Mechanical Aquatic Plant Control Permit' allowing us to remove up to 142.58 acres of plants. This permit also is very specific on what we do and how we do it.  To read the specifics of the lake's permit, click here: Mechanical Aquatic Plant Control Permit

Early in the spring of 2026 we are planning to chemically treat both South Shore and Jack's Bay with ProcellaCor in April (wheather and plant growth permitting around mid April).  Shorelines will be posted a couple days prior to treatment.

The Starry Stonewort remains in Pickeral Bay, and we are still asking those who can, to please stay out of Pickeral Bay and if you have to enter, be sure to reverse you motor before leaving.  Starry Stonewort is very aggressive and has not been a plant that can be completely destroyed.

Thank you for your patience as we try to return the lake to an acceptable condition.
