The Stoney called it Ho-run-num-nay meaning "lake of the little fishes" and it was a Stoney guide who took Canadian Pacific Railway (CPR) workman Tom Wilson to the site in 1882. Wilson named it Emerald Lake, but the name was changed (1884) to honour Princess Louise Caroline Alberta, fourth daughter of Queen Victoria and wife of Governor General the marquess of Lorne.
