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

This study delineates flood hazard areas and determines design flood levels along an approximate 31 km length of the Highwood River through High River. The design discharge for the Highwood River ranges from 750 m³/s at the upstream study extent to 650 m³/s at the downstream extent. Included in the study area are lands flooded by overflow from the Highwood River into the Little Bow River via Baker Creek and the Little Bow Canal, along approximately 3 km of Baker Creek and almost 1 km of the Little Bow River. The flood hazard mapping in a portion of the overflow area and along the Little Bow River is currently under review by Environment and Sustainable Resource Development. The study was prepared in August 1992. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.
