Swan Lake, Canada
Swan Lake is located in a park-like area in the City of Markham, Greater Toronto, Ontario. It was a former gravel pit where construction material was deposited when backfilling was carried out on the site. The pit was filled with water in 1980. Over time the pit has turned into a highly eutrophic, hard water lake with a history of poor water quality.
