These variables can potentially be influenced by river flow. Understanding the effects of flow and other factors on these important variables is critical for river management, particularly in the face of increasing demands on river resources. In this report, simple empirical methods are used to investigate the relationships between water temperature, DO, air temperature, and flow at two locations in the Red Deer River. Available water temperature, DO, discharge, and air temperature data were compiled for a number of sites along the Red Deer River. Compliance with water temperature and dissolved oxygen requirements for fish were evaluated at all sites using daily data. Non-compliance with acute and chronic temperature criteria occurred more frequently at stations located in the lower reaches of the river. Violations of oxygen criteria in the summer months were extremely rare; the lowest DO concentrations were recorded during winter months in the long-term monthly data sets.2015-08-24T19:25:12.619839+00:00https://open.alberta.ca/dataset/1b7496b9-b62f-448a-b3e8-d2a055a6af46Oxygen conditions in the Athabasca River system, with emphasis on winters 1990-932020-04-14T14:46:36.811024+00:00This report presents the findings of dissolved oxygen monitoring and surveys on the Athabasca River system in the years 1990-93. Dissolved oxygen has been monitored by means longitudinal synoptic surveys, recording oxygen meters, and a network of regular sampling sites.2015-08-20T19:50:08.854528+00:00https://open.alberta.ca/dataset/21a6d53a-9b87-403d-93d6-f8b90ffb14f8An evaluation of interference by pulp mill effluent in the Azid-Winkler oxygen technique2020-04-27T17:15:41.989422+00:00Bleached kraft pulp mill effluent contains a wide range of organic and inorganic compounds. This report examines if these compounds interfere with Azide-Winkler iodometric method of measuring dissolved oxygen.2015-08-25T19:51:06.610907+00:00https://open.alberta.ca/dataset/53d985ce-20ca-4850-a0a4-3913b529a27fAthabasca River winter reaeration investigation : final report2020-05-05T16:18:25.690295+00:00Proposed and existing pulp mill developments in the Athabasca River Basin impact on winter dissolved oxygen conditions in the rivers that receive their effluent. In 1987, Alberta Environment started using water quality models to simulate dissolved oxygen levels. This information was used to formulate effluent standards and for management of basin water quality. This report describes the theory of air to liquid gas exchange, methods to measure reaeration, the procedure designed to measure under ice reaeration, results of the field study, and conclusions from the study.2015-08-17T19:53:54.270108+00:00https://open.alberta.ca/dataset/82793404-d376-4b9e-a399-94da6e279b0aAlberta water quality guideline for the protection of freshwater aquatic life : dissolved oxygen2022-03-08T18:08:21.102910+00:00This guideline identifies the dissolved oxygen levels that are necessary to protect aquatic life in Alberta. The Government of Alberta, industries and municipalities will use the guideline to assess the potential for impacts of oxygen-consuming discharges from industrial and municipal wastewater treatment plants. The public can use the guideline as a reference when assessing the environmental health of their water.2015-08-25T19:10:24.535021+00:00https://open.alberta.ca/dataset/4f90d5d7-4075-40cd-bc43-abcb541830ecWater quality and phosphorus2023-09-06T19:33:57.579235+00:00Presents information about water quality and phosphorus. Phosphorous is not considered toxic in aquatic environments, but high concentrations heighten the potential for increased biological productivity and may lead to more frequent and widespread occurrences of algal and aquatic plant growth.2018-09-04T18:55:23.286330+00:00https://open.alberta.ca/dataset/2c91da55-d2b7-483a-9516-d9e93784252cBow River maximum allowable load, linkage of the total phosphorus sources and the dissolved oxygen target2023-10-18T22:18:22.747193+00:00This study calculated the Maximum Allowable Load for total phosphorus that the Bow River can receive while maintaining water quality standards (eg.
