Forest headwaters streamA myriad of small streams run through Vermont’s upland forests. These small streams represent the “headwaters areas” of a watershed. Headwater streams are the smallest but most abundant streams that drain our landscape. More than 75 percent of the total stream miles in the country are documented as headwater streams.

Vermonters love Lake Champlain.  We depend on the lake for fishing, swimming, boating, and other recreational pursuits.  It provides drinking water. Summer tourism and property values are tied to its health and beauty. The lake attracts businesses with a workforce that appreciates the lake’s natural beauty and Vermont’s working landscape.
