Have you noticed yellow particles floating on the water recently? It's pollen!
Pollen should not be mistaken for algae. It is yellow-green, dust-like, and floats mainly on the surface of water bodies.
In the spring and early summer, pollen from pines and other trees can fall onto the surface of the water forming a large yellow film. It may collect on the edge of shorelines or float for long periods in open water. It can also become water-logged and sink to the bottom.
While pollen is unpleasant for allergy sufferers, it is otherwise harmless.
