An extent of land covered by, intermittent and permanent, water bodies and watercourses. This includes both parcel bounding and non-parcel bounding occurrences. Includes the natural watercourses as follows: Bow River Elbow River Nose Creek West Nose Creek Fish Creek. This is a generalized version of the data set and is intended for cartographic purposes and faster drawing time.

The polygons delineate the boundaries of each of the major sub-watersheds within City of Calgary boundaries. These include Bow River Direct, Elbow River, Fish Creek, Nose Creek, Pine Creek and Shepard Wetland/Western Headworks Canal. The sub-watersheds delineate the major drainage areas within The City. Polygons should be layered over an orthophoto of Calgary, with the rivers, creeks and streams visible. This data is updated on an as needed basis by Watershed Strategy and has been simplified for viewing purposes.

This dataset contains results for the City of Calgary's Watershed Monitoring Program. The program monitors surface water quality across a network of sites that include rivers, tributaries, and reservoirs within the Calgary region. Sampling locations have been added, removed, or modified over time. Grab sampling methodologies are used for sample collection.

The City of Calgary uses approved and documented analytical testing methodologies, and the City of Calgary laboratory is accredited to the ISO/IEC 17025 standard. Quality Assurance programs track and ensure consistent laboratory performance. Changes in data over time, such as method detection limits, accredited testing parameters, and formatting are the result of newer analytical techniques and improved data quality standards.

Sampling locations for the City of Calgary's Watershed Monitoring Program

This dataset contains results from the City of Calgary's Wastewater Treatment Plants that are reported monthly to Alberta Environment and Protected Areas. Results include laboratory and flow data for the wastewater treatment plants’ treated effluents, 2007 to present. Sampling locations have been added, removed, or modified over time. All laboratory results have been determined from the daily 24-hour composite samples, with the exception of Fecal Coliforms which are determined from the grab sampling.
