Lake Louise, named Lake of the Little Fishes by the Stoney Natoka First Nations people, is a glacial lake within Banff National Park in Alberta, Canada, located 5 km west of the Hamlet of Lake Louise and the Trans-Canada Highway.
The emerald colour of the water comes from rock flour carried into the lake by melt-water from the glaciers that overlook the lake. The lake has a surface of 0.8 km2 and is drained through the 3 km long Louise Creek into the Bow River.
Fairmont’s Chateau Lake Louise, one of Canada’s grand railway hotels, is located on Lake Louise’s eastern shore. It is a luxury resort hotel built in the early decades of the 20th century by the Canadian Pacific Railway.
