Englesby Brook flows east to west across south central Burlington before eventually emptying into Lake Champlain in Burlington Bay. The brook’s headwaters originate within the Burlington Country Club near the South Burlington town line. Throughout its course, the brook flows through dense residential development. The brook itself is entirely within the city of Burlington; however, some of the watershed extends into the northern section of South Burlington. Approximately 84% of the watershed is within Burlington with 16% of the land within the city of South Burlington.
Burlington has a population of around 40,000 people and is the largest municipality within Vermont. The drinking water for the city comes directly from Lake Champlain, therefore protecting the lake and the areas that drain directly to it, such as Englesby Brook, is important. Because of its connection to Lake Champlain, Englesby Brook has been listed as a Significant Natural area within Burlington. The bacteria-impaired segment of Englesby Brook runs for its entire length, from the outlet on Lake Champlain north of Blanchard Beach, upstream to the headwaters within the Burlington Country Club. The Englesby Brook watershed covers 0.6 square miles, in the towns of Burlington and South Burlington. Overall, land use in the watershed is 20% forested, 4% agricultural, 75% developed, and 1% wetland.
Currently, the Stream Team is monitoring one site along Englesby Brook with the help of volunteers. Water samples are being taken twice monthly throughout the summer and are tested for phosphorous, nitrogen, chloride, and turbidity.

All of the data collected by Chittenden County Stream Team volunteers is shared with the State of Vermont Department of Environmental Conservation (VT DEC). The DEC shares all state-wide data with the Environmental Protection Agency.
