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).

The Waterfront Route is made up of ancient roads along the St. Lawrence, Lake Saint-Louis, Lac des Deux Montagnes, Rivière des Prairies, the Lachine Canal and the Aqueduct Canal. 180 kilometers long, it is punctuated by more than 1000 heritage elements that evoke the major pages of Montreal's history. Heritage buildings and complexes, maritime infrastructures, nautical equipment, parks and shoreline walks, views of bodies of water, coastal landscapes, natural environments and archaeological sites follow one another. Each of the heritage elements is associated with a historical theme: * The Montreal archipelago and the Native American presence * Rivers to trade and settle * Agricultural villages * Water, a resource to be exploited and controlled * Workers' villages * The shores, spaces for well-being and leisure * The parks on the banks * Water, an obstacle to be crossed by bridges and crossings * Transit villages * Other notable items not related to historical themes An [interactive map] (https://montreal.ca/articles/le-parcours-riverain-22677) is available to explore waterfront routes on Montreal Island.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The National Hydro Network (NHN) focuses on providing a quality geometric description and a set of basic attributes describing Canada's inland surface waters. It provides geospatial digital data compliant with the NHN Standard such as lakes, reservoirs, watercourses (rivers and streams), canals, islands, drainage linear network, toponyms or geographical names, constructions and obstacles related to surface waters, etc. The best available federal and provincial data are used for its production, which is done jointly by the federal and interested provincial and territorial partners. The NHN is created from existing data at the 1:50 000 scale or better. The NHN data have a great potential for analysis, cartographic representation and display and will serve as base data in many applications. The NHN Work Unit Limits were created based on Water Survey of Canada Sub-Sub-Drainage Area.
