What are Harmful Algal Blooms

IUPUI CEES Documents

  • Dense concentration of cells

  • Composed of microscopic cyanobacteria (also known as Blue-green algae)

Toxins
  • Some blue-green algae may produce toxins.

  • Toxins released through excretion from cells or as cells die

  • Harmful to aquatic life, pets, and humans

  • NOT all algal blooms produce toxins

What Causes Algal Blooms?
Blue-green algae photosynthesize the same as plants, they need:
  • Sunlight

  • Warm water temperature

  • Nutrients (fertilizer!)

  • Still Water Conditions

What Can Be Done to Reduce Blooms?
  • This is very difficult!

  • Reduce nutrient fertilizer input into the reservoir –Lakeside property owners –
    Fall Creek Watershed landowners

  • Algaecide treatment –Short-term solution; limited effectiveness –
    Only possible before bloom well developed –Not advisable if toxin-producing species present
