Residents were advised to take precautions and avoid drinking water from private water supplies that were impacted or draw from the area of the lake where blue-green algae was identified.
Blue-green algae blooms naturally occur in freshwater lakes, bays and inlets, usually during warmer weather. They thrive where water is shallow, nutrient-rich, slow moving and warm, but may also be present below the surface. Generally, cooler weather, rainfall, and reduced sunshine will lead to the breakup of an algal bloom.
The best method for managing algal blooms is prevention. Decreasing the amount of nutrients, such as phosphates and nitrogen, entering the water source can effectively reduce the occurrence and severity of algal blooms. This means using phosphate-free detergents, not using fertilizers on lakefront properties, taking steps to impede agricultural run-off, and ensuring that septic systems do not leak into the water source.
