We're here in cottage country, specifically Chemong Lake checking on some floating, emerging wild rice.
Checking on the overall water quality - It's been really hot so far this spring. With the heat (and climate change) the temperature of these lakes are constantly rising and with that you get what is called "blue green algae bloom".
This can be very dangerous to both animals and humans. With farming and ageing septics from cottages here (that we see along the shoreline) comes nutrient overload and with that nutrient overload comes an environment for this blue green algae to bloom and really take hold of this watershed.
We're checking on the state of the wild rice and as you can see it has become more prevalent. With wild rice, it actually purifies the water and creates great ecosystems for both birds and fish (for cover).
What is Blue Green Algae?
Cyanobacteria, or blue green algae is a type of bacteria that is most commonly found in wetlands and waterways (rivers, lakes and ponds).
Given the right conditions (such as a hot and humid summer), blue green algae can multiply quickly to form what are called "blue green algae blooms".
What Causes Blue Green Algae Bloom?
Nutrient overload from fertilizers and run offs from agriculture (and waste water) can contribute to blue green algae growth. Any type of nutrient run off can contribute to the growth of blue green algae.
Blue green algae flourishes in hot and humid climate conditions.
What Is The Danger of Blue Green Algae?
Once blue green algae dies it can release toxins into the water that can be dangerous for livestock, humans and pets. Any contact with infected waterways (from blue green algae) either through swimming, boating, canoeing, etc can cause a host of physical ailments (to humans) such as:
sore, itchy eyes
stuffed up feeling
If ingested, side effects may include
