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 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).**

The “Sub-basins of the AAFC Watersheds Project – 2013” dataset is a geospatial data layer containing polygon features representing the Standard Drainage Area Classification (SDAC) 2003 defined sub-drainages of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. Canada has eleven major drainage areas which are divided into 164 sub-drainage areas. All drainage areas and sub-drainage areas are named and have an identifying ‘number’. Sub-drainage areas have ‘numbers’ that share a common ‘three-character’ designation. For example, the 05A sub-basin contains stations ‘numbered’ 05AB006 and 05AC007.

The "Effective Drainage Area of the AAFC Watersheds Project - 2013" dataset is a geospatial data layer containing polygon features representing the areas of the Agriculture and Agri-Food Canada's (AAFC) Watersheds Project that could, for the entire project areas, be expected to contribute to surface runoff under average runoff conditions.

The "Total Effective Drainage Areas of the AAFC Watersheds Project – 2013” dataset is a geospatial data layer containing polygon features representing the areas within the “total gross drainage areas” of each hydrometric gauging station of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project that would contribute to average runoff. A ‘total gross drainage area’ is the maximum area that could contribute runoff for a single gauging station – the ‘total effective drainage areas’ are those parts of that ‘total gross drainage area’ that would contribute surface runoff to an average runoff. For each “total gross drainage area” there can be only one “total effective drainage areas”. These polygons may overlap with those from other gauging stations’ “total gross drainage area”, as upstream land surfaces form part of multiple downstream gauging stations’ “total gross drainage areas”.

The “Incremental Effective Drainage Areas of the AAFC Watersheds Project– 2013” dataset is a geospatial data layer containing polygon features representing the portions of each incremental gross drainage area of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project that could be expected to contribute to surface runoff under average runoff conditions. An ‘incremental gross drainage area’ is a hydrometric gauging station's drainage basin, less that of the next upstream gauging station(s)’. ‘Effective drainage’ occurs in areas that are expected to supply surface runoff in an average runoff.
