These sheets present the annual results of periphyton monitoring in Quebec lakes. Periphyton is a microecosystem composed of algae, bacteria, and other forms of life that thrive on various submerged surfaces in shallow areas of aquatic environments. Since 2012, the team from the Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (MELCCFP) responsible for the Voluntary Lake Surveillance Network (RSVL), in collaboration with various partners, has been offering local residents' associations and organizations involved in the protection of lakes the opportunity to monitor periphyton. This monitoring makes it possible to detect signs of eutrophication in the coastal zone, that is to say in the shallow areas located near the shore.

The sheets are available from the [Directory for downloading the annual periphyton monitoring sheets] (https://stqc380donopppdtce01.blob.core.windows.net/donnees-ouvertes/RSVL/Periphyton/Repertoire_fiches_periphyton.html). The lakes are identified by their name and number from the Quebec Lakes and Rivers Database (LCE).
