About Blue Green Algae and Blooms
Wind and waves can move algae around. Blooms can appear or disappear very rapidly so conditions around the lake are likely to change over the course of the week.
- To check on the current status of your favorite beach or swimming area, contact whoever is responsible for maintaining the beach. This may be the town, Vermont State Parks, or a private association.
- It is not possible to tell whether algae blooms are toxic by looking at them. Everyone should become familiar with the appearance of blue-green algae blooms and avoid them.
- See examples of what Blue-green Algae does and does not look like here.
Be cautious and avoid blooms
- Children are at higher risk because they are more likely to play near the shoreline and drink water while swimming.
- Pets will also drink the water and lick off algae that may be caught in their fur.
- Avoid boating, jet-skiing and swimming through blooms
