Filamentous Algae (Spirogyra, cladophore and many other varieties)

This is commonly referred to as “pond scum”. It has a thread like appearance and often forms surface mats. Growth begins at the bottom of shallow water or on structures in the water and rises to the surface as oxygen becomes trapped by the filaments.

Concern: Algae blooms have been a major factor in fish kills as dissolved oxygen levels are depleted. It can cause interference with fishing and swimming.
