If you like spending time in nature and enjoy fishing at your favorite lake during the summer and early fall, you may notice an unusual discoloration on the surface of the water. Increasing temperatures combined with sunlight and nutrients that run off the surrounding landscape can combine to form this surface – known as algal blooms.
These blooms form from naturally occurring blue green algae, but under the right conditions, they can potentially produce harmful toxins that pose a health concern to humans and animals. Below are a few common questions and answers that will help keep you and your loved ones safe:
How do I know if it is a harmful algal bloom?
- Algal blooms are often identified by discolored water: bright green, blue, brown, red or a milky paint color on the water surface. The only way to confirm that an algal bloom is harmful is through laboratory testing.
What should I do if I suspect a harmful algal bloom is present in the water?
- If you notice brightly colored or discolored water, you and your pets should avoid contact with the water. NC Division of Health and Human Resources (NCDHHS) advises, “When in doubt, stay out!”
