Description

Twin Valley Reservoir was first filled in 2003 following construction of a new dam on the Little Bow River near its confluence with Mosquito Creek. To fill and operate the new reservoir, increased diversion from the Highwood River to Women’s Coulee and to the Little Bow River occurs in spring according to an approved water management plan. An existing lake, Clear Lake, was also stabilized by diversion from Mosquito Creek near the mouth first operated in 2002, and additional enhancements. This report presents an evaluation and statistical analysis of water quality in Twin Valley Reservoir, Clear Lake, and their tributaries that was prepared using intensive monitoring data collected by Alberta Environment from 1999 to 2010, with reference to previous baseline sampling where needed for statistical testing.

Description

The report describes the fish communities of the Little Bow River and Mosquito Creek, based on the results of field sampling conducted in 2014. 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 2014, the fish assemblages in the Little Bow River and Mosquito Creek were 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

Numerous beneficial management practices (BMPs) have been developed and promoted to minimize the impacts of agriculture on the environment and increase the sustainability of the agricultural industry. However, the effectiveness of BMPs under Alberta conditions is not well known. This study evaluates the effectiveness of nutrient BMPs on water quality improvement in prime agricultural regions in Alberta, at field and watershed scales, in order to provide viable options for sustainable agriculture and water quality protection.
