Our 2025 CLP report showed great success in controlling CLP in Grove Lake! With any invasive plant, efforts are made to eliminate the plant from the lake. Current treatments are extremely effective, but is difficult to completely eradicate due to dormant turions and weather patterns.

Sadly, the winter/spring conditions of 2025-2026 created the perfect conditions for the dormant turions for prosper. The May 2026 survey showed an exponential increase in CLP. If it weren't for our efforts these past years, the CLP would have completely taken over the lake. The GLLA board will be taking efforts for treatment in May 2027.

Grove Lake was treated with herbicides, specifically for invasive CLP, on May 1, 2025 by PLM Corporation. The treatment does not have any affect to fishing, swimming or pets. It is advised to not water your lawn with the lake water in treated areas for 5 days post application. All affected houses have a neon orange sign on your shoreline.

The cost of the survey and treatment was $4,984. Because of our board members' efforts, Grove Lake received a grant to cover 80% of the treatment cost! If you have any questions, please contact the Lake Management Plan Director listed on the "Contacts" page.
