Description

A diversion from the Red Deer River to raise the water level in Buffalo Lake began in Spring 1996. Water quality monitoring has been conducted to ensure the project does not lead to the degradation of water quality in the lake with the diversion in place. The reports below contain the findings of the monitoring studies.

Description

Alberta Envrionmental Protection has intensively monitored the Bow River ecosystem since 1989. This work was designed to determine the distribution of contaminants from the Canada Creosote site in the aquatic ecosystem, to protect domestic water supplies and to ensure the human consumption of fish was safe. This report evaluates changes in water quality over the two years since the containment system was intalled.

Description

Increasing development pressure at Wizard Lake prompted the counties of Leduc and Wetaskiwin to review the lake management plan that was adopted in 1980. One of the main issues relevant to further development is water quality of the lake. The planning committee members asked Alberta Environmental Protection to provide updated information on the lake’s water quality, particularly whether it had changed over the years. This report summarizes available data and updates a phosphorus budget that had been prepared for the lake several years ago.

Description

A water quality study was initiated on the Red Deer River to address water quality concerns experienced by the Anthony Henday Water Treatment Plant during periods of runoff. The study was designed to document longitudinal changes in water quality in the Red Deer River between the Dickson Dam and the City of Red Deer, and to evaluate the effects of contributions from the Little Red Deer and Medicine rivers on Red Deer River water quality during spring runoff.

Description

This document provides a summary of the numeric and descriptive water quality values applied in Alberta. It is intended to be used as a screening tool for the evaluation of water quality monitoring date and for setting approvals limits for effluent discharges. If during the review of monitoring data guidelines are not exceeded, problems are unlikely. On the other hand, if the guidelines are exceeded, a detailed assessment might be required to determine the extent of and/or the possible sources of the exceedance and the potential adverse effects arising from the exceedance.

Description

In view of potential coal mine development in the Mountain Park area of the upper McLeod River and upper Cardinal River basins, Alberta Environmental Protection carried out a one year sampling program to obtain baseline data on water quality and benthos in the project area which would serve to complement and corroborate data being collected by the proponent. This report provides basic information on the methods used and compiles the data obtained during the program.

Description

In 1992, Water Sciences Branch began an intensive study of Thunder Lake to determine the cause of increasing algal growth and poor water quality. Of particular interest was a diversion to the lake from a tributary of the Paddle River, which was suspected of increasing the lake’s supply of phosphorus and nitrogen. The purpose of the monitoring program was to assess 1) changes in water quality in the lake, 2) the quantity of phosphorus and nitrogen in the diversion water compared with other nutrient sources, 3) what the lake would be like if the diversion is discontinued, 4) other ways to maintain water quality in Thunder Lake. This report highlights the results of this study.

Description

This report summarizes the information gathered on the water quality of Field Lake during the initial period of study (1981 - 1986) and from three sets of samples collected during the summer of 1997. The impact of the effluent discharge is assessed by comparing 1) water quality two years before and four years after the discharge began, 2) concentrations of substances in the lake water with relevant Alberta and Canadian water quality guidelines, and 3) 1985-86 data with 1997 data.

Description

Lesser Slave Lake is the third largest lake in Alberta and supports important fisheries, provincial parks, recreation areas, water supplies, and other uses. The lake has been well investigated with respect to fisheries but a comprehensive water quality or limnological survey has not been carried out on it previously. To document existing water quality of the lake and its major inflows, particularly with regard to nutrient and algal conditions, a water quality survey was conducted in the 1991-93 period. The two main basins of the lake, five tributaries, and the lake=s outflow were sampled monthly during the ice-free season, and additional sampling was done on the inflow and outflow of Buffalo Bay.
