Eurasian Water Milfoil
In 2001, patches of the Eurasian Water Milfoil were detected in the lake and needed to be dealt with quickly. Local members came together to bring in a biologist and engineers to provide treatments that kept the water unpolluted, aquatic life safe, and did not require extensive treatments in the long run. Using sunlight-blocking fabric and milfoil weevils, the Eurasian Water Milfoil population began to decrease.
The link below gives further information and photos on the treatment of the Eurasian Water Milfoil within Higgins Lake from 2001 through 2007.
Starry Stonewort Report
During a scuba evaluation of boat activities at 33 locations, divers discovered dense patches of Starry Stonewort and Eurasian Water Milfoil at 3 DNR sites. Reporting to the state with requests to close the DNR sites until these patches are dealt with to prevent further spread within the lake and other bodies of water was denied.

Michigan DNR AIS Control Plan
View the plans and goals to restrict and treat aquatic invasive species (AIS) at DNR boating access areas. These locations are the navigational channel at North Higgins Lake State Park, the lagoon at South Higgins Lake State Park, and the west launch.
A detailed list of Goals, AIS Control Methods, and Actions to Date can be found at the link below.
DNR Boat Accesses on Higgins Lake
After years of discussion with the DNR about their boat accesses, data was collected over 2023 and 2024 at South State Park, North State Park, and West Access to see the rate of boats that carried AIS outside of the lake. With data supporting a high number of contamination rates, there are recommendations that can decrease the spread of AIS within Higgins Lake and other inland lakes.
To see the full recommendations made, view the project information below.
Presentation to DNR & Parks and Recreation
Two presentations were conducted by the HLPOA and DNRPRD Chief Ron Olson to help improve AIS prevention and spread at Higgins Lake, as well as other inland lakes.
With the help of the DNRPRD and other lake associations (Crystal, Glen, Leelanau, Lime), have agreed to work together forming a Michigan Invasive Species Partnership (MISP) to provide each other with data and information for better protection.
After continued talks, more prevention and actions have been proposed to help negate the spread and reduce the amount of AIS across inland lakes.
