The Riparian Areas Assessment of the Swan River, Lesser Slave River and Tributaries, West Prairie, and Lesser Slave Lake focused on assessing riparian habitat along creek, stream and river shorelines. This dataset was created for the Lesser Slave Watershed Council as a part of a large scale riparian area assessment in Alberta. The overall goal of this project was to quantify and characterize the riparian habitat management in the Lesser Slave Lake watershed by assessing riparian areas along approximately 2536 km of shoreline. This study created a recent land cover layer within 50 m of selected shorelines and use this layer to assess the intactness of riparian areas along major waterbodies. It also provided guidance on how the results from the intactness assessments can be used to target conservation and restoration efforts within along the shorelines that were assessed as part of the study.

All available bathymetry and related information for Lesser Slave Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

Great Slave Lake in the Northwest Territories is one of the most important areas for inland breeding gulls and terns (larids) in northern Canada. Numerous rocky islands on the North Arm provide breeding habitat for a number of colonially-nesting larid species. Great Slave Lake is the only known breeding site for Caspian Terns in the Northwest Territories and the North Arm is the northernmost known breeding range for the species in North America. Given its importance to a variety of migrating, nesting and staging birds, various portions of the area have been recognized as; a Key Migratory Bird Terrestrial Habitat site, an Important Bird Area, and an International Biological Program site. This dataset contains results from surveys of active larid breeding colonies from between 1986 and 2010 on the portion of the North Arm west of Yellowknife. Most data were collected through ground surveys, with travel by boat, between mid June to early July. Information recorded at each colony included species, numbers of nests, clutch size, presence of chicks, and habitat characteristics (vegetation cover). The majority of larid colonies were located on islands along the northeastern shoreline. The southwest shoreline saw limited use by nesting larids due to the reduced number and different characteristics of the islands in that area. The most regularly occurring species were Herring Gull, Mew Gull, Ring-billed Gull, California Gull, Common Tern, Arctic Tern, and Caspian Tern.Results of these surveys have been published in the report “Gull and Tern Breeding Colonies on the North Arm of Great Slave Lake, Northwest Territories: 1986-2010 (Woodard, Fournier, and Robertson, 2013).

The Thaidene Nëné (thy-Den-ay nen-ay) area is a celebrated cultural landscape with rich wildlife populations and unique geography located at the eastern end of Great Slave Lake in the Northwest Territories. The initial Thaidene Nëné study area was approximately 33,690 km2. Thaidene Nëné means ‘Land of the Ancestors’ in the Dënesųłı̨né language.

The dataset includes subsurface stratigraphic picks for the formations that comprise the Beaverhill Lake Group (Townships 29 to 113, Ranges 1W4 to 13W6) made from wireline geophysical well logs. The dataset also includes picks for the underlying Elk Point Group, and the overlying Woodbend Group. Lithostratigraphic picks for the Beaverhill Lake Group include the Fort Vermilion Formation, the Swan Hills Formation, the Slave Point Formation, and the Waterways Formation (top of the Beaverhill Lake Group). Lithostratigraphic picks for the underlying Elk Point Group include the Prairie Evaporite Formation, the Sulphur Point Formation, and the Watt Mountain Formation (base of the Beaverhill Lake Group). Lithostratigraphic picks for the overlying Woodbend Group include the Cooking Lake Formation, or its equivalent.
