Kootenay Lake

Kootenay Lake is a lake located in British Columbia, Canada. It is part of the Kootenay River. The lake has been raised by the Corra Linn Dam and has a dike system at the southern end, which, along with industry in the 1950s–70s, has changed the ecosystem in and around the water. The Kootenay Lake ferry is a year-round toll-free ferry that crosses between Kootenay Bay and Balfour. The lake is a popular summer tourist destination. Kootenay Lake is a long, narrow and deep fjord-like lake located between the Selkirk and Purcell mountain ranges in the Kootenay region of British Columbia. It is one of the largest lakes in British Columbia, at 104 km in length and 3–5 km in width. It is, in part, a widening of the Kootenay River, which in turn drains into the Columbia River system at Castlegar, British Columbia. Although oriented primarily in a north-south configuration, a western arm positioned roughly halfway up the length of the lake stretches 35 km to the City of Nelson. The lake is 532m above sea level, with the adjacent mountains rising up to a maximum of approximately 2700m. The average residence for water in the lake is 1.5 years, although the west arm has a much faster rate of water replacement; about 3–4 days. Kootenay Lake was formed through river erosion and, later, glaciation. The erosion began during the late Cretaceous until ice filled the resulting valley in the Pleistocene. When the valley was filled with ice, glaciers from the mountains (the Selkirks and Purcells) fed the valley's ice mass. The glacier that occupied what is now the west arm of Kootenay Lake flowed into the Kootenay ice mass. As the ice melted from this glacier, drainage flowed over an area near what is now Nelson, causing the west arm of the lake to drain toward the west. A large moraine formed near what is now the large bend in the Kootenay River near Libby, Montana. As ice melted, a lake formed behind the moraine and drained southward over top of it. The southerly drainage over the moraine eventually stopped and the Kootenay River began to follow its present course.

Kutenai

The Kutenai (ˈkuːtəneɪ,_-niː ), also known as the Ktunaxa (tʌˈnɑːhɑː ; ktunʌ́χɑ̝), Ksanka (kəˈsɑːnkɑː ), Kootenay (in Canada) and Kootenai (in the United States), are an indigenous people of Canada and the United States. Kutenai bands live in southeastern British Columbia, northern Idaho, and western Montana. The Kutenai language is a language isolate, thus unrelated to the languages of neighboring peoples or any other known language. Four bands form the Ktunaxa Nation in British Columbia.

Sinixt

The Sinixt (also known as the Sin-Aikst or Sin Aikst, "Senjextee", "Arrow Lakes Band", or—less commonly in recent decades—simply as "The Lakes") are a First Nations People. The Sinixt are descended from Indigenous peoples who have lived primarily in what are today known as the West Kootenay region of British Columbia in Canada and the adjacent regions of Eastern Washington in the United States for at least 10,000 years. The Sinixt are of Salishan linguistic extraction, and speak their own dialect (snsəlxcín) of the Colville-Okanagan language.
