Description

This study delineates flood hazard areas and determines design flood levels along the South Saskatchewan River as well as Ross and Seven Persons Creeks through Medicine Hat. The study area includes an approximate 35 km reach of the South Saskatchewan River, an approximate 3 km reach of Ross Creek and an approximate 11 km reach of Seven Persons Creek. Ross Creek joins Seven Persons Creek less than 1 km upstream of its confluence with the South Saskatchewan River. The design discharge for the South Saskatchewan River is 5230 m³/s. The design discharge for Ross Creek is 152 m³/s. The design discharge for Seven Persons Creek is 121 m³/s upstream of the Ross Creek confluence and 273 m³/s downstream of the confluence. The original study was prepared in May 1986. An addendum with updated flood hazard mapping was published in February 1991. The original report, addendum and updated mapping constitute the revised study. Flood information available after study completion may not be reflected...

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 investigates extreme flood events which have been experienced in the past and makes conclusions as to the cause. It investigates the Brazeau and Bighorn Dams and their effects on peak flows through the City for selected flood events. Lastly the report investigates the available data and establishes the frequency of various flood magnitudes.

Description

In 1962 the Hydrology Division of the Department of Water Resources, in response to a request to the Department of Water Resources from the City of Calgary City Engineer, began a study of the potential flooding danger along Elbow River in an attempt to delineate the areas which would likely be under water for various probabilities of flood occurrence.
