This list of 18 Water Level and Flow monitoring stations along the South Saskatchewan River Basin (Bow and Elbow River watersheds) is derived from a much larger repository of sites in Alberta. Select sites upstream of Calgary as well as sites in Calgary are included. This data is collected from remote monitoring stations and therefore is not thoroughly checked for accuracy. This is intended for preliminary analytical purposes and is subject to change.

Data provided through this web app is provisional and preliminary in nature. Data is automatically generated by remote equipment that may not be under control of the Government of Alberta. This data has not been reviewed or edited for accuracy and may be subject to significant change when reviewed or corrected. Please exercise caution and carefully consider the provisional nature of the information provided. The Government of Alberta assumes no responsibility for the accuracy or completeness of this data and any use of it is therefore entirely at your own risk.

Average daily weekday traffic (ADWT) is the average number of vehicles in 24 hours adjusted for seasonal variation to represent the average weekday. The numbers on this map are two-way totals.

This is data collected from the sanitary sewer system by area velocity type open channel flow meters.
*QAQC'd data that has been finalized is tagged as '1' under the Edited column.*

The traffic volume flow map illustrates the Average Annual Weekday Traffic (AAWT), the average number of vehicles in 24 hours adjusted for seasonal variation to represent the average weekday. The numbers on the map are two-way totals.

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.

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.

Total annual river withdrawals is the total volume of water withdrawn from the Bow and Elbow rivers measured in megalitres (ML).
