Base waterbody polygon arcs are feature type, source and capture date attributed arcs that make up the boundaries of base waterbody polygons in the Base Features Hydrography geospatial dataset. These arcs were collected from conversion processes of 1:20 000, 1:50 000 and AVI Provincial mapping...

Critical habitat is identified for species listed as Endangered or Threatened under the federal Species at Risk Act (SARA) and where federal critical habitat protection orders are in effect. Fisheries and Oceans Canada (DFO) is the responsible authority for the protection, recovery and...

The data represents the density of wetland habitat in the agricultural region of Alberta in 2002. Wetlands are depressional areas that are wet for a long enough period that the plant and animals living in them are adapted to, and often dependent on, living in wet conditions for at least part of...

Flood maps are created by combining hydraulic model results with high-accuracy ground information. Field surveys and LiDAR remote sensing are used to collect river and floodplain elevations, channel cross section data, bridge and culvert information, and flood berm details. A hydrology assessment...

The Watershed Planning and Advisory Councils (WPAC) boundaries contained in this dataset are an approximate representation of the WPAC planning areas in Alberta. The actual boundary used by individual WPACs may differ from what is contained in this data.These boundaries were derived from the...

Base Hydrography Update Index depicts the extent of the current HUC 8 (Hydrologic Unit Code) watersheds completed in 2018-2021.

The Base Hydrography Point Update layer contains hydrographic point features representing the locations of water or water related features, it is an updated of the Base Features Hydro Points in Southern Alberta from orthophoto and various sources of provincial base data.

The Fish Management Zone dataset is comprised of all the polygons that represent the Fish Management Zones in Alberta. Fish Management Zone is an area having its own unique assemblage of water bodies, species of game fish and management regimes.

This map displays an assessment of surface water quality risk for the agricultural area of Alberta. Agricultural activities that may have an impact on surface water quality, including livestock, crop production and agrochemical use, were identified and used to produce this map. The classes shown...

The Base Hydrography Point Event layer contains hydrographic point features representing the locations of water or water related features captured through the 1:20000 Provincial Base Mapping Project, the 1:50000 Resource Access Mapping Program, the Alberta Vegetation Inventory Program and the...

The Base Hydrography Single Line Hydrography Network (SLNET) is the Alberta Environment and Parks base SLNET data set. It is an update of the Base Features HydroSLNET in Southern Alberta from orthophoto and various sources of provincial base data. It contains all captured single line...

The data represents the relative expense of fertilizer and lime in the agricultural area of Alberta. It is an estimate of the degree to which agriculture may affect nutrient levels in surface and groundwater. The classes shown on the map are ranked between 0 (lowest) and 1 (highest).Mapping the...

Distribution (range) polygons were assembled by regional SARA biologists using the best available information, including COSEWIC status reports, recovery potential assessments, academic literature, and expert opinion. These spatial data support the protection, recovery and conservation of species...

The Aquifer Vulnerability Index (AVI) is a method of assessing the vulnerability of aquifers to surface contaminants in Alberta. An aquifer is a geological formation that is permeable enough to transmit sufficient quantities of water to possible to support the development of water wells. In the...

This dataset shows length weighted connectivity values summarized by hydrologic unit code (HUC) for a provincial stream connectivity indicator that assesses connectivity for aquatic organisms in stream networks. The stream connectivity indicator supports evaluation and reporting on indicator...

This map displays an assessment of groundwater quality risk for the agricultural area of Alberta. Agricultural activities that may have an impact on groundwater quality include livestock, crop production and agrochemical use. These activities along with the physical characteristics represented by...

The Alberta ArcHydro Phase 2 Data was developed to support the delineation of catchment areas in the province of Alberta. It was generated using a DEM which had the Base Stream and Flow Representation (Single Line Hydrography Network) burned (excavated) into it. The data is divided into eighteen...

Sub-regional plans support working landscapes that provide economic opportunities and maintain healthy landscapes by outlining management approaches and requirements for development and human footprint restoration. These plans enable public lands to support the interests of all Albertans,...

Base Waterbody Polygon Update is the Alberta Environment and Parks base hydrography polygon dataset, it is an updated of the Base Features Hydro Polygons in Southern Alberta from orthophoto and various sources of provincial base data.

This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. Riparian areas consist of the lands adjacent to streams, rivers, wetlands and lakes that...
