Description

This study delineates flood hazard areas and determines design flood levels along the Bow River and Exshaw Creek through Municipal District of Bighorn, including Exshaw. The study area includes an approximate 15 km reach of the Bow River and an approximate 1 km reach of Exshaw Creek. The design discharge for the Bow River ranges from 728 m³/s at the upstream study extent to 762 m³/s at the downstream extent. The design discharge for Exshaw Creek is 14.3 m³/s. The study was prepared in February 1996. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Description

Water quality in southern Alberta's Bow River, as measured by bacteriological indicators, has been affected by increasing population and development in the Bow Basin. This report documents levels of coliform bacteria in the Bow River for three time periods: 1951-52, 1967-75, and 1978-94, and includes data compiled from all agencies sampling in the Bow River basin for over 45 mainstem sites and for a number of tributaries.

Description

This study delineates flood hazard areas and determines design flood levels along the Bow River and Policeman Creek through Canmore. The study area includes an approximate 20 km reach of the Bow River and an almost 6 km reach of Policeman Creek. The design discharge for the Bow River is 673 m³/s upstream of the Policeman Creek confluence and 698 m³/s downstream of the confluence. The design discharge for Policeman Creek ranges from 95.8 m³/s at the Bow River confluence to 37.2 m³/s farther upstream, in a non-overflow area. The study was prepared in March 1993. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Cochrane - Bow River, Bighill and Jumpingpound Creeks - flood hazard study

This study delineates flood hazard areas and determines design flood levels along the Bow River and Bighill and Jumpingpound Creeks through Cochrane. The study area includes about 27 kilometres of... More ≫

Description

This study delineates flood hazard areas and determines design flood levels along the Bow River and Bighill and Jumpingpound Creeks through Cochrane. The study area includes about 27 kilometres of the Bow River, almost five kilometres of Bighill Creek and about five kilometres of Jumpingpound Creek. Ice jam flooding is the design condition along the Bow River. The study uses analysis of historic ice jam data at River Avenue Bridge to determine 100-year ice jam water levels along the Bow River mainstem. Open water flooding is the design condition for Bighill and Jumpingpound Creeks. The design discharges for Bighill and Jumpingpound Creeks are 20.8 m³/s and 323 m³/s respectively. The headwaters of the Bow River are in the Rocky Mountains upstream of Lake Louise. Although there are a number of storage reservoirs in the basin upstream of Cochrane, their primary purpose is to provide hydroelectric power and thus they offer little opportunity to moderate flood flows. The original study...

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.
