Description

A partnership of agricultural, residential, and recreational landowners concerned about water quality and low flow in Grand Valley Creek was formed in 2002. Alberta Environment provided a water quality sampling and flow gauging program in this watershed in 2003, to document current conditions in this basin and assist planning by this partnership. This sampling program focused on key water quality variables in Grand Valley Creek that may be indicative of impacts from ranching or wastewater from septic fields.

Description

To assist the development of plans for the Highwood and Little Bow River watersheds, the Science and Standards Division, Alberta Environment was asked to examine the relationship between flow and water quality in the Little Bow River and Mosquito Creek. This report presents an evaluation of the effects of flow on water quality. Equations were developed to predict the relationship between flow and dissolved oxygen in the Little Bow River, and the relationship between flow and total suspended solids in Mosquito Creek. These equations were used to estimate flows that should ensure suitable water quality.

Description

A water quality sampling program was initiated by Alberta Environment in the Little Bow River and Mosquito Creek basins in 1999. This program was intended to document the water quality impacts of agriculture and municipal wastewater discharge in these basins, and identify the most important loading sources (critical areas) for phosphorus, nitrogen, and total suspended solids (TSS).

Evaluation of recent trends in water quality in the Elbow River upstream from Glenmore Reservoir

Description

Water Sciences Branch, Alberta Environment (AENV) was asked to determine if any significant changes had occurred in the water quality of the Elbow River upstream from Glenmore Reservoir, since the... More ≫

Description

Water Sciences Branch, Alberta Environment (AENV) was asked to determine if any significant changes had occurred in the water quality of the Elbow River upstream from Glenmore Reservoir, since the previous survey by the Alberta government (Beers and Sosiak 1993). All the available water quality data for the Glenmore Reservoir and the upper Elbow River were compiled and evaluated. Those variables with a sufficient number of samples were then tested statistically to determine whether significant changes in concentration had occurred over time.

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... More ≫

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.
