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 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.
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.
