This dataset contains measurements of water (chemistry and algal pigments) and sediment (chemistry and size fraction) quality in nearshore areas of Lake Huron surrounding cage aquaculture operations including North Channel, Manitoulin Island and Georgian Bay. Seasonal ice-free monitoring and sampling occurred in Ontario nearshore areas between 1998-2016. The dataset also contains the limits of detection and quantification for the parameters measured, GPS coordinates and depths (sample, Secchi, composite and maximum) for the lake sampling locations.

The National Ecological Framework for Canada's "Land and Water Area by Province/Territory and Ecoprovince” dataset provides land and water area values by province or territory for the Ecoprovince framework polygon, in hectares. It includes codes and their English and French descriptions for a polygon’s province or territory, total area, land-only area and large water body area.

This list contains water meters operated by the City of Montreal Water Department. The meter pool is used to carry out water balances and makes it possible to measure the water distributed to the other municipalities forming the agglomeration of Montreal. This list is a view of the situation at the time the file was generated. NOTE: The data in this set aims to have a better understanding of the number of industrial, commercial and institutional water meters installed as part of the City of Montreal's water consumption measurement strategy. For reasons of challenges in the protection of third party industrial secrets, the consumption associated with these meters will not be published.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This theme includes the drainage areas of various watercourse monitoring stations (physicochemical and bacteriological, benthic organisms, diatoms, pesticides, etc.) carried out by the Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (MELCCFP) as well as lake catchments (MELCCFP) as well as lake catchments including the majority of lakes in the Voluntary Lake Monitoring Network (RSVL). The drainage area and the watershed represent the territory whose water flows to the sampling station or to the outlet of the lake. Boundaries are generated using a geographic information system (GIS) from topographic maps, numerical elevation models and flow models, and watershed boundaries produced by the Main Directorate of Water Expertise (DPEH). The drainage area and watershed are used to calculate the area drained upstream of the sampling station or lake, to characterize the drained territory (for example, to determine land use), and to meet specific mapping needs. The linked tables also provide compilations of land use according to three classifications to contextualize the various monitoring carried out at the stations. Note that the use of land outside Quebec, drainage areas and transboundary watersheds is not calculated and that the percentages in each category correspond to the Quebec area only.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The “Gross and Effective Drainage Areas for Hydrometric Gauging Stations of the AAFC Watersheds Project - 2013” dataset is a table that provides the calculated gross and effective drainage areas associated with the hydrometric gauging stations of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. Areas are provided in square kilometres. ‘Gross drainage’ describes the total area of a catchment. ‘Effective drainage’ describes areas that are expected to contribute to an average runoff.

The National Ecological Framework for Canada's "Total Land and Water Area by Ecozone” dataset provides land and water area values for ecozone framework polygons, in hectares. It includes attributes for a polygon’s total area, land-only area and large water body area.

The mapping of flow beds during periods of low water or in a retention basin in the City of Laval can only be used for information purposes. Any drainage bed present on a site must be analyzed, as part of an environmental study carried out by the applicant for a permit or authorization certificate, in order to confirm whether it is a ditch or a watercourse. The map can be modified at any time by the City of Laval to reflect the most up-to-date data it has.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
