That now extends to the Carseland Weir, west of Gleichen on the Bow, which feeds into the South Saskatchewan River near Grassy Lake.
Rivers that feed the Bow upstream of Calgary could rise between three to five feet on Friday, though the effect on the main stem of the Bow will be much less, Alberta Environment stated Friday.
