The Sherbrooke Lake Water Quality Program was implemented in fall 2017, with 2018 observing the first full sampling year. The program was designed by the Sherbrooke Lake Stewardship committee to obtain a baseline and monitor changes in water quality of the lake before, during, and after the development of a public access site. The program is managed by Coastal Action, with a group of trained volunteers collecting monthly and rainfall-dependent samples. Coastal Action also sits on the committee, in addition to a technical water quality expert, and citizen and municipality representatives from both the Municipality of Chester and the Municipality of the District of Lunenburg.
