Lake Water Quality Program
The Lake Water Quality Program was formed in 2001 after the amalgamation of the new City of Greater Sudbury to ensure the overall health of the City's lakes. Our goal is to improve and protect the quality of the community's surface water through lake water quality monitoring and encourage community engagement through lake stewardship groups and the volunteer help of residents.
Our mandate:
- To monitor various water and shoreline quality parameters of local lakes and work collaboratively with other City divisions, government agencies, lake stewardship groups, and individual residents to address problems as they arise.
- To promote the creation of stewardship groups on individual lakes.

On February 6, 2025, residents were invited to a virtual information session on boating activities on local lakes. The purpose of the community webinar was to provide information on Transport Canada’s Vessel Operation Restriction (VORR), enforcement of boating regulations and shoreline protection as it relates to boating activities. Representatives from Transport Canada, the Greater Sudbury Police Service Marine Unit, Conservation Sudbury and the City of Greater Sudbury attended to answer questions.
