When fertilizers that contain Nitrogen and Phosphorus wash off of lawns and gardens during rain storms, algae in streams and lakes have more nutrients available to grow. This is referred to as an algal bloom. Algal blooms can be different colors but generally appear as scum on the surface of the water. During the bloom, dissolved oxygen levels increase. Near the end of the bloom, decay by bacteria increases which consumes dissolved oxygen causing fish and macro-invertebrates to suffer.
