Algae Monitoring

Algae are microscopic plant-like organisms at the base of lake food webs. They add oxygen to the waterand are critical to fueling zooplankton, small fish, and ultimately large fish growth. Like many things though, when there gets to be too much of them they become unpleasing, a nuisance, and even outright dangerous.  Some kinds produce toxins that are harmful to human health.  The kinds that produce toxins are types of “blue-green” algae (cyanobacteria).

In addition, zebra mussels can change a lake’s algae composition as zebra mussels eat certain kinds of algae.

Monitoring what’s in the water can help to understand what’s at the base of lake food webs, determine pre or post zebra mussel conditions, and can keep lake users safe.
