blue green algae

Figure Caption: Blue-green algae monitoring of Geist Reservoir by the Central Indiana Water Resources Partnership shows that the presence of high levels of blue green algae has been detected in Geist Reservoir consistently over the past three years. State officials advise rinsing off after any water contact and not allowing pets to drink raw water when levels exceed 100,000 cells per milliliter (above the red line).
