Algae are simple, typically small aquatic organisms and range in structure from unicellular (a microscopic single cell) to multicellular and as they produce and grow, form colonies that appear on the surface or attached to various substrates. Algae are always present in lakes and rivers, and are at the base (primary) of most lake food webs, and as such, are critical components of a healthy aquatic environment. Without algae, zooplankton (small animals that feed on algae) would not survive, and this would impact the survival of fish and other animals further up the food chain.
When conditions are favourable, certain populations of algae can increase to levels that result in poor water quality and an algal bloom or scum may form. Bloom-forming conditions include:
As there is an abundance of relevant literature covering the identification, reporting and relevant health implications, this introductory material has been limited to the above general information on algal growth and a list of key findings relevant to Kahshe and Bass Lake property owners/guests or public users. A more detailed report on the types of algae that may impact the health of Kahshe and Bass Lakes, on factors that play a role in algal bloom development and on the health symptoms and use restrictions has been developed and is appended. Also appended to this section are several excellent references to help readers better understand the health and aesthetic implications of a toxic algal bloom and how the presence of a bloom needs to be reported.
The key findings relevant to Kahshe and Bass Lake property owners/guests/users include:
This section of the Lake Health tab will serve as a repository for any future algal bloom alerts and associated health advisories.
