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.

The Agriculture and Agri-Food Canada’s (AAFC) Watersheds Project level series supplies a number of watershed and watershed related datasets for the Prairie Provinces. The levels are greater or smaller assemblages of hydrometric areas, or the components defining them. The Project is organized by hydrometric gauging stations which are sourced from Environment Canada, the United States, and Canadian provinces. Additional stations were generated to address structural issues, like river confluences or lake inlets. Collectively, they are referred to as the gauging stations, or simply, the stations. The drainage area that each station monitors, between itself and one or more of its upstream neighbours, is called an ‘incremental gross drainage area’. The incremental gross drainage areas are collected into larger or smaller groupings based on size or defined interest to generate the various ‘levels ’of the series. They include: Basins of varying size: 1. Major drainage systems (3): Arctic Ocean, Hudson Bay and Gulf of Mexico; 2. Major basins (23): associated with river or lake reaches; 3. Project sub-basins (47): created specifically for the project; 4. Sub-basins (51): based on specific Environment Canada hydrometric gauging station locations; 5. Sub-sub-basins (311): based on specific Environment Canada hydrometric gauging station locations); Incremental drainage areas: 6. Incremental gross drainage areas: one per gauging station. The incremental gross drainage areas are further subdivided into portions that either contribute or do not contribute to drainage to an average runoff event. The portions that do contribute are called ‘effective drainage’ areas, while those that don’t are called ‘non-contributing’. These generate the following levels: 7. Incremental effective drainage areas; and 8. Incremental non-contributing areas. Total drainage areas: 9. Total gross drainage areas; 10. Total effective drainage areas; and 11. Total non-contributing areas; And when combined for the entire project, yields the: 12. Effective drainage area. The series also includes the components: 13. The gauging stations; 14. The collection of boundaries (lines) of the gross incremental drainage areas as well as the boundaries that separate contributing from non-contributing areas for an average runoff event; and 15. A network of downstream-directed lines that connect the gauging stations. All linework is derived from large scale topographic data. One additional non-spatial dataset, a table of tallied values by gauging station, is provided: 16. The Project Gauging Station Table. The Project area, designed for the Prairie Provinces, covers all of Alberta, Saskatchewan and Manitoba, and those portions of British Columbia, Northwest Territories, Nunavut, Ontario, and the United States that are required to complete the trans-border sections of the watersheds. Since 1975 the AAFC Watersheds Project has systematically collected and refined watershed boundaries for the Prairies. The result is the authoritative source for gross and effective drainage areas in the Prairie Provinces. The initial 1:50,000 analog delineations were moved to their digital form in 1994. Since then, the delineations have increased in accuracy and extent, and the series levels have increased to 16 in number.

The main objective of this sampling program was to assess the effects of the spill on the toxicity of surface water collected during the spill by comparing them with the results of water collected prior to the discharge.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The “Gross and Effective Drainage Area Boundaries of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing line features representing boundaries associated with the ‘incremental gross drainage areas’ of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The project is subdivided by hydrometric gauging station. The maximum area that could contribute runoff to each station, less that of its upstream neighbour(s) is called its ‘incremental gross drainage area’. Two types of boundary are provided: ‘gross’ and ‘effective’. ‘Gross’ boundaries separate adjacent incremental gross drainage areas. ‘Effective’ boundaries delimit, within each incremental gross drainage area, the separation between areas that supply runoff, based on average runoff, from those that don’t.

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).**

The “AAFC Annual Unit Runoff in Canada" data series illustrates runoff trends across the country by isolines of annual unit runoff for a variety of probabilities of exceedence commonly used by decision makers Annual unit runoff is a measure of runoff volume per square kilometre. This series uses units of cubic decametres (1000 m3) per square kilometre (dam3/km2), which is equivalent to millimetres depth on the landscape. It includes a point data set for the hydrologic stations that were analyzed and seven sets of line work to show the adjusted isolines for 10%, 25%, 50%, 70%, 75%, 80%, and 90% probability of exceedence.

The "Hydrometric Gauging Stations of the AAFC Watersheds Project - 2013" dataset is a geospatial data layer containing point features representing the hydrometric gauging stations of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The gauging stations are sourced from Environment Canada, the United States and Canadian provinces. Additional virtual stations have been generated to address hydrometric structural issues, like river confluences or lake inlets. Attribute information includes station identification, location and associated catchments/basins.
