The dataset contains data for placer watersheds locations. The dataset covers 18 watersheds within the Yukon Territory. The following watersheds form the principle boundaries of the dataset: Big Creek, Big Salmon River, Forty Mile River Indian River, Klondike River, Mayo River McQuesten River, Nisutlin River, Nordenskiold River Pelly River, Sixty Mile River, Southern Lakes (Yukon) Stewart River, White River\*, Yukon River North Yukon River South, Alsek River, Liard River \*Note - A small portion of the headwaters of the Tanana River (Yukon) watershed is associated within the boundaries of the White River watershed .Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The bedrock topography map of the Pelican River area (NTS 83P) shows the elevation of the bedrock surface. In general, the surface topography reflects the bedrock topography: bedrock highs underlie the Pelican, Amadou and May Hills highlands, and the buried valleys lie within the Wabasca and Wandering River plains. The elevation of the bedrock surface ranges from 360 metres above sea level (masl) in the Wabasca Plain to slightly more than 920 masl in the Pelican Mountains. Segments of three major buried valleys are present: the Wiau Valley and the Leismer Valley in the northeast, and the south to northwest-trending Amesbury Valley in the central portion of the area.

The purpose of this dataset is to identify the location of river valley connections.

Baseline of a creek or river means a traverse line following the general direction of the centre bottom lands of the valley of the creek or riverDistributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The names of these rivers in the Bay of Fundy and Port Hawkesbury Area Response Plan (ARP) regions were obtained from Recovery Potential Assessments (see references), and cross referenced with the Atlas of Canada hosted online by Natural Resources Canada. These rivers were then identified and marked in ArcGIS using the Nova Scotia and New Brunswick Hydrographic Networks. Point features were used to represent the river mouths. For rivers large enough to be represented by polygon features, the point was placed where the polygon closed the inlet. For smaller rivers represented by a polyline, the point was placed where the line intersected the coastline. When multiple tributaries of a river were identified as salmon rivers, only the most seaward was marked.Cite this data as: Corrigan, S. Data of: Salmon Rivers Presence, Maritimes Region.

The drift thickness map of the Pelican River area (NTS 83P) shows the variation in thickness of unconsolidated sediment lying between the bedrock surface and the present-day land surface, and complements the regional drift thickness map of Alberta (Pawlowicz and Fenton, 1995). The thickness of the drift varies from less than 20 metres in uplands, such as the Pelican Mountains, to a little over 260 metres in the Wiau Valley in the northeast part of the map area. The thickest drift fills the paleovalleys containing the major valleys: the Wiau Valley and the Leismer Valley in the northeast, and the north-trending Amesbury Valley in the central portion of the area.

The Waterbodies dataset is comprised of area features: lakes, intermittent waterbodies, islands, and rivers wide enough to be represented as an area feature (e.g. St. Lawrence River, Mackenzie River). In a few exceptional cases, islands had to be represented by "holes" in the polygons in the Waterbodies dataset. Some area features have been subdivided and several types of virtual linear features serve to separate them. Features in this dataset are linked (by an attribute) to their corresponding flow line in the Drainage Network Skeleton. Therefore the Waterbodies dataset may be used in conjunction with the Drainage Network Skeleton for analytical applications. The Islands dataset is comprised of area and linear features: islands within inland waters and the waterbodies and single line rivers within these islands. Oceanic islands are not included as they are part of the coastline component of the Drainage Network Skeleton dataset. The Islands dataset exists to complete the cartographic representation of Canadian hydrology. The Islands dataset is not logically connected with the Drainage Network Skeleton, and can not be used for analytical applications. It should be noted that flow lines of the Drainage Network Skeleton do not take into account of the existence of islands and therefore do not necessarily flow around them. In a few exceptional cases, islands had to be represented by "holes" in the polygons in the Waterbodies dataset. Some islands themselves contain waterbodies and rivers, not significant for network analysis. However, in order to support a complete cartographic representation such waterbodies and rivers have been added to the Islands dataset. The National Scale Frameworks Hydrology data consists of area, linear and point geospatial and attribute data for Canada's hydrology at a national scale. It provides a representation of Canada's surface water features, and data completeness reflects the content of the source, the original Vector Map level 0 (VMAP0) revision 4 hydrographic layers, except where revision editing has been performed. Key value-added characteristics include river flow direction, connectivity and the tagging of geographical name keys to selected rivers, lakes and islands included in the Concise Gazetteer of Canada.The Atlas Frameworks are a set of integrated base map layers which form part of a larger National Scale Frameworks data collection. These data have been compiled at a scale of 1:1 000 000 with the primary goal being to indicate correct relative positioning with other framework layers rather than absolute positional accuracy.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
