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...
