Description

The report describes the fish community of the Little Bow River, based on the results of field sampling conducted in 2005 and 2006. Assessment of the fish community was completed as part of the Twin Valley Dam environmental monitoring program. Monitoring was intended to determine the environmental impacts of the construction and operation of Twin Valley Dam and the effectiveness of environmental mitigation measures. In 2005 and 2006, the fish assemblage in the Little Bow River was generally unchanged compared to previous post-dam monitoring results. The Little Bow River fish assemblage is influenced by entrainment of fish from the Highwood River upstream from the Twin Valley Dam Reservoir and by movement and migration of fish from Travers Reservoir, downstream from Twin Valley Dam.

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).

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.
