LAKE LOUISE Louise, Lake, glacial lake in south-western Alberta, Canada. Lake Louise is located at an elevation of 1,731 m (5,680 ft) in Banff National Park, near the town of Lake Louise. The lake is about 2.4 km (1.5 mi) long and 1.2 km (0.75 mi) wide. Sheltered by the Rocky Mountains, Lake Louise is known for the tranquil beauty of its turquoise-blue surface, which mirrors nearby scenic forests and snowcapped peaks. The lake is fed from the north by the spectacular Victoria Glacier and is drained by the Bow River in the south-east. Lake Louise was named in 1884 after the Canadian Governor-General's wife, who was also the fourth daughter of Queen Victoria. The lake became a tourist attraction after the Canadian Pacific Railway route passed nearby, and the company built the grand hotel, Chateau Lake Louise, on the shore of the lake.
