Blue-green algae
Blue-green algae has been spotted at South Beach this year. Blue-green algae are photosynthetic bacteria that are a natural part of the aquatic environment and are often present in Illinois lakes in small or moderate amounts. However, these organisms can grow and proliferate quickly in warm, fresh water that is rich with nutrients (like nitrogen and phosphorous), which results in an algal “bloom”. This type of bloom has been spotted in Loch Lomond before.
Blue-green algae can cause illness in people and animals, and, though the LLPOA is implementing lake management methods including aeration, spraying, and regular water quality testing to reduce the risk of algal blooms, there could be more beach closings due to blue-green algae this summer.
If you believe you’ve come across blue-green algae in Loch Lomond, remember the following tips:
- Do not swim or fish near the algal bloom
- Send an email to LLPOAboard@lochlomondlake.com noting the location
- Always rinse off after being in the lake
- Don’t let your dogs drink lake water or lick it off their fur
- Rinse dogs off immediately if they swim through an algal bloom
