Description

Total dissolved solids, conductivity and major ions have increased over time in Muriel Lake and that increase is linked to the drop in lake levels and the concentration of dissolved substances in the water. The salinity of the Muriel Lake has increased, although it still qualifies as a slightly saline water body. Phosphorus and chlorophyll a have increased slightly, but the database is insufficient to determine whether these changes are related to the decline in water levels or simply reflective of year-to-year variability. The lake has remained mesotrophic. Low winter dissolved oxygen levels, recorded under ice in recent years, are a concern for fisheries in Muriel Lake.

Description

In 1989-1990 Alberta Environment undertook a study of the water quality of the Battle River from its source to its confluence with the North Saskatchewan River. This report provides a non-technical summary of the study design, major findings and conclusions presented in two other major reports: "Water Quality of the Battle River" and "multi-Media Monitoring of Trace Metals and Pesticides in the Battle River 1989-1990".

Description

This report addresses two issues concerning the bacterial quality o the lower Red Deer River: 1) the increase in fecal coliform counts and incidence of non-compliance with water quality objecgives set by the Prairie Provinces Water Board (PPWBO) at the Alberta-Saskatchewan border, 2) the implications of discontinuing chlorine treatment of the Drumheller, East Coulee and Rosedale final municipal effluents on bacterial quality of the Red Deer River.

Impacts of agriculture on surface water quality in Alberta

Description

Part 1 -The Haynes Creek Study was one of three studies funded under the Canada-Alberta Environmentally Sustainable Agriculture agreement (CAESA) to describe the effects of agriculture on surface waters in Alberta. This study was conducted in the Haynes Creek watershed to determine if runoff from cattle wintering grounds and from cultivated fields had a direct, measurable influence on stream water quality. The Haynes Creek watershed (east of the city of Red Deer) was selected because it was considered representative of very intensive agricultural activity on a landscape sensitive to water erosion. Part 2 - The Provincial Stream Survey was one of three studies funded under the Canada-Alberta Environmentally Sustainable Agriculture agreement (CAESA) to describe the effects of agriculture on surface waters in Alberta. This study was conducted to determine if there are relationships between the agricultural intensity in the drainage basins and water quality of streams. Part 3 - Federal...

Description

Temperature and dissolved oxygen (DO) are important water quality variables which affect the viability of fish and other aquatic organisms. 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...

Description

Water quality surveys were conducted in the Beaver River in the fall 1991 and in spring 1993 to 1) describe the effects of the spring and fall discharges from the Cold Lake/Grand Centre Regional Sewer System and from the continuous treated municipal wastewater discharges from the Canadian Forces Base-Cold Lake; and 2) determine if the long-term PPWB monitoring site at Beaver Crossing is representative if the Beaver River water quality that enters Saskatchewan.

Description

The Multi-Media Monitoring Pilot Program on the Battle River was undertaken to assess and compare the suitability of water and other media such as bottom sediments, suspended sediments, suspended sediments and biota (plants, invertebrates, and fish) for monitoring heavy metals and pesticides. Development or enhancement of sampling and analytical protocols and evaluation of seasonal longitudinal trends in contaminant levels were important components of this assessment.
