Forest Lake Alum Treatment
The alum treatment will take place on Forest Lake during the last week of September 2025
The Forest Lake Alum Treatment Project is a milestone project in achieving Forest Lake’s water quality goals. The lake was treated with alum which binds to phosphorus and makes it unavailable for algae growth. Alum is a non-toxic water quality treatment that results in a cleaner and clearer Forest Lake.
The first phase of the Forest Lake Alum Treatment was completed during the week of September 25th to 29th, 2023.
The second phase of the Forest Lake Alum Treatment will be completed during the week of September 29th to October 3rd, 2025.
