Harmful Algal Blooms

Algae, or phytoplankton, are essential components of healthy lakes. However, under the right conditions, algae can grow rapidly to achieve high abundance. This is a bloom. Some algae, called cyanobacteria, can produce toxins that are harmful to humans and pets. This is a harmful algae bloom.

This workshop introduces participants to algae and to the cyanobacteria that may be problematic. It also explores different ways that harmful algal blooms are detected as well as some things you can do to reduce the probability of a bloom in your lake.
