During a bloom, the water becomes less clear and may look green, blue-green or greenish-brown, which can produce harmful toxins. You can’t tell if an algal bloom is toxic just by looking at it, so it’s safest to assume it is. Keep pets and children away from the water and avoid skin contact with the water or algae. | |
