What is an algae bloom?

  • It is an abundant algae growth that can be made up of many organisms, including blue-green algae (Cyanobacteria).
  • Warm temperatures, sunshine, wind, and nutrients promote the growth of algae blooms.

Why are we concerned?

  • Algae blooms can be a nuisance in recreational waters.
  • Certain types can be hazardous to humans and pets.
  • They can harm fish and wildlife.

What are we doing?

Lake sediment sampling

  • Will determine if these blooms are caused by human activity, or if they are part of a naturally occurring cycle.

Water sampling

  • Will determine water quality, availability of nutrients, and the types of algae present.
