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.

This GIS dataset depicts the surficial geology of the Lesser Slave River area (NTS 83O/SE) (GIS data, line features). The data were created in geodatabase format and output for public distribution in shapefile format. These data comprise the line features of Alberta Geological Survey Map 553, Surficial Geology of the Lesser Slave River Area (NTS 83O/SE) (GIS data, line features).

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.

PURPOSE:This study is part of a two-decade series of research aimed to provide a comprehensive synthesis of the effects of harvest and environmental change on fisheries in Great Bear Lake. The main objectives are to assess demographic traits and the current status of harvested species, with a focus on evaluating sustainable harvest levels of lake trout, a cold-adapted species with a relatively narrow thermal niche. As part of this research, trends in water quality and primary productivity are monitored to evaluate potential effects of change on fisheries. DESCRIPTION:Great Bear Lake, one of the largest lakes in North America, contains culturally and recreationally important fish species. Great Bear Lake is located in the sub-Arctic and Arctic Circle. As part of a two-decade series of research aimed to provide a comprehensive synthesis of the effects of harvest and environmental change on fisheries in Great Bear Lake, the main objectives of this study are to assess demographic traits and the current status of harvested species, with a focus on evaluating sustainable harvest levels of lake trout, a cold-adapted species with a relatively narrow thermal niche. As part of this research, trends in water quality and primary productivity are monitored to evaluate potential effects of change on fisheries. From 2021 to 2024, surface water temperature data was collected at depths of 0.1 to 1.0 meters using an RBR Maestro3 through partnered community-led and community/Fisheries and Oceans Canada/university partner collaborative sampling. The project has strong community involvement, including youth through the Guardian Program, to facilitate capacity building and community leadership in the long-term monitoring of Great Bear Lake fisheries and the aquatic ecosystem. This data is an extension of baseline data sets on water quality on the lake. These data will contribute to a better understanding cumulative impacts of climate change on the functioning of large northern lake ecosystems and provide a benchmark for monitoring further change. This data will be important for developing effective strategies for maintaining community-led aquatic monitoring and managing natural resources, particularly fish, which are expected to be increasingly important to communities with declines in other country foods such as caribou.We acknowledge the data were collected in the Sahtú Settlement Area and are made publicly available with the agreement of the Délı̨nę Renewable Resources Council (Délı̨nę Ɂehdzo Got’ı̨nę (Renewable Resources Council)). Collaborators include: the Community of Délı̨nę partners (data collection), Délı̨nę Renewable Resource Council, Sahtú Renewable Resource Board, and University of Manitoba. Community of Délı̨nę partners and field workers that participated in data collection include Chris Yukon, Archie Vital, Ted Mackienzo, Daniel Baton, Lloyd Baton, Simon Neyelle, and Stanley Ferdanan.Funding and logistical support was provided by: Northwest Territories Cumulative Impact Monitoring, Sahtú Renewable Resource Board, the Polar Continental Shelf Program and Fisheries and Oceans Canada.

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.
