3-4 Sweden The Swedish whitewater rivers are mainly big water and is located in the middle and north parts of Sweden. One of the most spectacular rivers is Vindelaelven and particularly Trollforsarna III-VI, where one Euro cup competition was held in 2007. The main information channel for Swedish white water is Forsguiden, North America Canada Canada has a varied terrain that supports many kinds of environments, with the majority of whitewater found in three areas: the mountainous Rockies in Alberta, the smaller Eastern forests of Quebec, Ontario, and some of the Maritimes, and the volcanic influenced geology of British Columbia. This creates the conditions necessary for whitewater: gradient, volume, and pressure. Like its neighbor to the south, First Nations had used the river systems as personal highways and built dugout canoes to run rapids; later French Canadian fur trappers used the same technique to collect beaver pelts and form small settlements. Canadian whitewater rivers are characterized by the dramatic difference between the high water spring run-off and the summer low water volume; the classification of rapids therefore changes from spring to summer. It also is highly subject to the change of seasons, where many places are frozen solid by October and, for example, runs that are ready in late May in the neighboring US Pacific Northwest are still too dangerous to attempt in British Columbia or too cold: the spring run-off of the glaciers has either not finished or the landscape is not fully thawed. Most of the land in Canada is not privately owned and likewise neither are the rivers. Many places in which water thunders through the terrain are on land that is either protected or very remote, so knowledge of first aid and the local wildlife is paramount. As with the United States to the South, rattlesnakes, grizzly bears, black bears, mountain lions, wolves, and two members of the lynx family are very much active at the height of rafting and kayaking season, and they do use the water as a source of food and sustenance. On multi day excursions in The Northwest Territories, British Columbia, or Alberta it is extremely important to know or learn to coexist with the grizzly bears that live there; this is particularly true when it is salmon season. Caution should be used whenever camping in bear country, and learning how to properly store food or anything with a scent is paramount
