• Cyanobacteria Blooms

  Cyanobacteria, also known as blue-green algae, occur naturally in lakes and ponds throughout Connecticut.  These microscopic organisms often go unnoticed and cause no harm.  However, excessive nutrient pollution and climate change are causing waterbodies to experience more frequent nuisance cyanobacteria blooms that may produce and release toxins.  When cyanobacteria blooms release toxins, people and animals using the water body for recreation can have health effects.  It is important to note that not all algal blooms are harmful algae blooms (HABs), however it is not possible to determine the level of toxins in the water without a more detailed evaluation. Out of precaution it is best to avoid direct contact with water experiencing a bloom.  When in doubt, stay out!
