“Scums” of blue-green algae may occur in stagnant ponds or dugouts following hot, dry, calm days. Animals may die suddenly (within minutes) after drinking water heavily contaminated with this scum. Blue-green algae (also called Cyanobacteria) occur naturally in many ponds. There are a number of different species: some are harmless; some form toxins that affect the nervous system; others produce toxins that affect mainly the liver. This publication from South Dakota State University covers diagnosis, prevention, and control.
