Teaching about lake management is an exciting way of getting students interested in the environment. It offers hands-on opportunities for students of all ages to learn about the biology and chemistry of lakes.

Humans rely on lakes for many reasons, including drinking water, cropland irrigation, and recreation. Additionally, lakes provide habitat for a variety of aquatic life, such as fish, microscopic animals called zooplankton, aquatic plants, and algae.
