Description: Point dataset representing locations of all significatn dams in Saskatchewan. The source of this data is the Water Security Agency's "Dam Safety Database". More information about WSA's Dam Safety Database:In 1987, a database of dams having a storage capacity of greater than 30 cubic decametres was created using, in part, data assembled from the provincial Surface Water Regulatory database. Additional file information such as dam height, and the name of the watercourse on which a dam was sited, was added to create the Dam Safety Database (aka Dams Inventory Database). Modest efforts since 1987 have been made to maintain the database current.More information about dam safety and WSA's Dam Safety program:Dam safety is a management system or process which provides protection for the public and environment against the consequences of a failure or misoperation of a dam. It is primarily an ownership responsibility; however, in recent years it has become an emerging issue involving government participation. Dam safety pertains to new, existing and closed dam projects encompassing the full project life cycle including design, construction, operation and decommissioning. Dam safety systems or processes include responsibilities, policies, plans and procedures, documentation, training, review and correction of deficiencies and non-conformances. The main elements of a dam safety program are: documentation of design, construction and performance; operation procedures; inspection; review; and response and warning procedures. The main tools of a dam safety program are: operation, maintenance and surveillance manuals; emergency preparedness manuals; dam safety reviews and decommissioning plans. Documentation provides up-to-date permanent records of the design, construction, operation, and performance, all of which affect the safety of the dam. Qualified and trained personnel are required to perform dam safety program activities. The dam owner is principally responsible for dam safety and regulatory compliance.

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).

Description: The M181 sub basins of Taits Lake and the Climax Group have had their borders changed to match those fromt Agriculture Canada's Gross Drainage dataset. There was also two "gaps" or areas of no data that needed to be included in the dataset.
