Wetlands in the Basin

Click here to view enlarged map as 1,843 KB PDF file. Wetlands are transitional areas between dry land and water bodies. They may contain fresh or salt water. They may be temporary or permanent, static or flowing and they come in a variety of sizes, shapes and depths. Water is a necessary ingredient but does not have to be present at all times. Some are wet all year long and some are wet for only a part of the year. Wetlands vary in size from as much as a few hundred square feet to thousands of acres.

The Lake Champlain Basin contains more than 300,000 acres of wetlands as shown on the Wetlands in the Basin Map [1,843 KB]. As large as this figure sounds, approximately 35 to 50 percent of the wetlands have been lost in the Basin due to development pressures and landscape modification. These losses are often incremental in nature, as wet areas are filled in one acre at a time.

Wetlands improve water quality by filtering sediments, pollutants and nutrients; provide habitat and nourishment for fish and wildlife; protect groundwater and drinking water supplies; and provide habitat for rare, threatened and endangered species, and natural communities. They also stabilize shorelines and prevent erosion; provide recreational opportunities; control flooding, contribute to the aesthetic quality of the landscape; and provide educational opportunities.

Located along the Atlantic flyway, a migratory corridor for waterfowl and other wetland birds, Lake Champlain wetlands provide critical resting and feeding sites during the fall and spring migration. Between 20,000 and 40,000 ducks and geese have been counted on flights during early October. Over 30 species of waterfowl use Lake Champlain annually, including black ducks, wood ducks, mallards, blue winged teal, common goldeneye, hooded mergansers, and Canada geese.
