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 “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 “PFRA Sub-basins of the AAFC Watersheds Project – 2013” dataset is a geospatial data layer containing polygon features representing the 47 sub-basins within the Agriculture and Agri-Food Canada (AAFC) Watersheds Project, tailored for the Prairie Farm Rehabilitation Administration (PFRA) business needs.

This product provides runoff data with each contour line corresponding to an average amount of annual runoff (in millimeters). Runoff data were derived from discharge values from hydrometric stations with natural flows. Not all years are included for every region of the country due to data quality and availability issues. Data cover the period 1971 to 2013 for the south and 1971 to 2004 for the north. These files were produced by Statistics Canada, Environment, Energy and Transportation Statistics Division, 2017, based on data from Environment and Climate Change Canada, 2015, Water Survey of Canada, Archived Hydrometric Data (HYDAT), www.ec.gc.ca/rhc- wsc/default.asp?lang=En&n=4EED50F1-1 (accessed December 3, 2015); Spence, C. and A. Burke, 2008, “Estimates of Canadian Arctic Archipelago runoff from observed hydrometric data,” Journal of Hydrology, Vol. 362, pp. 247–259. For more information about methods, results and limitations see Appendix D in Statistics Canada, 2017, “Freshwater in Canada,” Human Activity and the Environment, Catalogue no. 16-201-X. The purpose of the dataset is to present runoff values as derived from Statistics Canada's Water Yield Model on a national scale map of 1:32,000,000. This product is intended to be used for reference or mapping purposes. The product ends at the shoreline of Canada as defined by the drainage region boundaries supplied for Map 1.1 Drainage regions of Canada. It does not include the Arctic Islands. Users are responsible for verifying that the product is appropriate for their intended application.

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).**
