Munroe Brook originates in Shelburne between Barstow Road and Governor’s Lane with a small portion extending to the north into South Burlington. The stream flows south-west,  under Spear Street. It then continues north-west where it flows and continues under Route 7 before emptying into Lake Champlain in Shelburne Bay. Multiple smaller tributaries enter the main stem along its course.

Urban development has led to urban runoff and erosion along Munroe Brook.  The entire Munroe Brook watershed draining to Lake Champlain is approximately 14.1 km.  The entire stream and its tributaries are Class B waters designated as warm water fish habitat pursuant to the Vermont Water Quality Standards. The land use breakdown of the watershed draining to the impaired reach is 29% developed lands, 38% agricultural or open lands and 33% forested. (VTDEC 2008)

Shelburne is located on beautiful Lake Champlain in Chittenden County. Designated as the Lake Champlain Scenic Byway, U.S. Route 7 passes through our community and is the home of Shelburne Museum, Shelburne Farms, and many other tourist attractions.

In 2013, the Stream Team began monitoring two sites along Munroe Brook with the help of volunteers.  Water samples are being taken twice a month throughout the summer and are tested for phosphorus, turbidity, chloride and nitrogen.
