Lakes and Ponds

A lake or pond is a body of water confined to a natural depression in the earth’s surface called a basin. They are different from rivers and streams because their waters are comparatively still. Statewide, there are over 6,000 lakes and ponds which provide a vital resource for recreation, agriculture and as a source of drinking water for both people and domesticated animals. These diverse freshwater reservoirs also provide vital habitat for wild aquatic and terrestrial species.
