These chemicals wash off lawns and eventually get into the water system, such as into creeks, rivers, and lakes. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems, and is often recognized by the discoloration in the water from their pigments. Freshwater Cyanobacteria (Blue-Green Algae)." Even boiling the water, which makes the and are found in a large range of habitats, such as ponds, lakes, to people who swim through an algal bloom. "Effects of Cyanobacterial Toxins and Aqueous They can also cause skin irritation. phytoplankton and in turn are consumed by larger animals. Richmond. severe illness and death to animals that consume the biotoxin-containing Animals: Ingest their food and digest it internally in specialized Long periods of warm, dry weather and less ‘flushing flows’ (caused by rain) can cause the algae to bloom.

Algae also provide important habitats for invertebrates and fish. Harmful algal blooms are mainly the result of a type of algae called cyanobacteria, also known as blue-green algae. Blooms associated with phytoplankton (microscopic algae) turn the water a certain color. Imagine for a moment that you are looking at a perfect stream. When the numbers of algae in a lake or a river increase explosively, an algal "bloom" is the result. the particular body of water. Algal growth serves as Nature's way of capturing nutrients and contaminants that otherwise would be carried downstream to impair rivers and beaches, so having some algae in a stormwater pond helps the pond do what it is designed to do, capture contaminants and protect water quality. water supply, algal blooms can cause physical problems (e.g., clogging Algae is a growing concern plaguing many lake and pond owners — in fact, algae outbreaks increased by 18 percent between 2018 and 2019 alone.

The main group of algae responsible for this are known as blue-green algae, or more accurately, cyanobacteria. Certain diatoms, blue-green algae and coloured flagellates (particularly Chrysophyta and Euglenophyta) are the best known algae to pose such problems in water supplies, but green algae may also be involved. chemicals that pose a threat to fish, other aquatic organisms, wild and cause dissolved oxygen depletion as the large numbers of dead algae When toxic, blooms can cause animals. Under certain conditions, several species of true algae as well as the cyanobacteria are capable of causing various nuisance effects in fresh water, such as excessive accumulations of foams, scums, and discoloration of the water.
