Canmore drinking water path

• Source & supply

  Rundle Forebay (Spray Lakes / Kananaskis via TransAlta canals)

  Shallow groundwater aquifer beneath downtown Canmore (hydrologically connected to Bow River)

  Serves Canmore plus MD of Bighorn neighbours (Harvie Heights, Dead Man's Flats, Lac des Arcs). North of TransCanada Highway generally wells; south/central from Rundle Forebay.

  Canmore does not take potable water directly from the Bow River; Spray Lakes hydro storage feeds the Rundle Forebay that supplies most of town.
