Description: The majority of the reservoirs in this dataset were manually "heads-up" digitized by WSA staff based on SPOT 5 (2.5 metre pixel) imagery captured in 2006 (exact date(s) for each reservoir are in the attribute table). One of the reservoirs, Watson Reservoir (created by Avonlea Dam) was digitized from the 2009 SGIC photography. The polygons for three of the reservoirs: Chicken Lake, Kipahigan Lake, and Lac LaRonge, were taken from the NTS 1:50,000 scale GIS dataset from Natural Resources Canada.For the polygons that were digitized by WSA from imagery, certain decision rules were followed in delineating the extents of the reservoirs; specifically:All visibly dry land, such as dry beaches and dry mud flats, was excluded from the reservoir polygons during the digitization process. Conversley, those beaches or mud flats that appear to be saturated with water were included as part of the reservoir polygons. Islands found within the reservoirs were digitized and removed from the reservoir polygons (i.e. they are represented as "holes" in the polygons). For the purposes of determining the extents of the reservoir polygons (i.e. where to cut them off), "reservoir" was defined as the areas of the waterbodies that are significantly influenced by the dam/structure. Note that this is a somewhat subjective decision; for example, as to where a river ends and a reservoir starts).
