Description

In 2002 Alberta Environment initiated several studies on Wabamun Lake in response to public concerns about murky water near the TransAlta Utilities Corporation ash lagoon outfall and to follow-up on incidences of fish mortality. Elevated metal levels were found in the water and sediments near the ash lagoon outfall, but the cause of fish mortality was unrelated to these metal levels. The objective of this study was to determine if the sediments contained substances toxic to aquatic life forms.

Description

Alberta Environment initiated a detailed survey of the Elbow River in 1988 to develop a basin overview of water quality. The specific objectives of this survey were to 1) assess the effects of existing development on water quality on the Elbow River upstream of Calgary; 2) examine phosphorus loading patterns and determine major sources; and 3) provide baseline data to assess the effects of future development.

Description

This report presents the results of 1986-88 Bow River water quality monitoring programs conducted by Alberta Environment. Plant nutrient, coliform bacteria count and aquatic plant biomass trends and differences between sites were analyzed. This program was mainly designed to detect changes in river water quality since the installation of phosphorus removal at Calgary sewage treatment plants in 1982-83.
