Banff National Park is Canada's first national park and the world's third. Spanning 6,641 square kilometres (2,564 square miles) of valleys, mountains, glaciers, forests, meadows and rivers, Banff National Park is one of the world's premier destination spots.

In the fall of 1883, three Canadian Pacific Railway construction workers stumbled across a cave containing hot springs on the eastern slopes of Alberta's Rocky Mountains. From that humble beginning was born Banff National Park, Canada's first national park and the world's third. Spanning 6,641 square kilometres (2,564 square miles) of valleys, mountains, glaciers, forests, meadows and rivers, Banff National Park is one of the world's premier destination spots.

"The North Saskatchewan River watershed in the province of Alberta, Canada stretches across Central Alberta from the Rocky Mountains in the west, to the border with the province of Saskatchewan in the east. Hydrologicaly, it is divided into twelve (12) tributary sub-watersheds with a total drainage area of about 57,000 square kilometres.
It is home to approximately 1.2 million people, most of whom live in the Alberta Capital Region (City of Edmonton and area). The watershed is made up of a complex diversity of natural land forms and ecological regions, which supports a wide range of human land uses." -http://www.nswa.ab.ca/content/overview
