Rupert River

The Rupert River is one of the largest rivers in Quebec, Canada. From its headwaters in Lake Mistassini, the largest natural lake in Quebec, it flows 600 kilometres (370 mi) west into Rupert Bay on James Bay. The Rupert drains an area of 43,400 square kilometres (16,800 sq mi). There is some extremely large whitewater on the river, but paddlers can avoid much of it by portage routes on the side. The most impressive falls, which cannot be avoided except by portaging, are the "Oatmeal Rapids" right at the James Bay Road (a set of cascades dropping 18 m (59 ft)) and "The Fours" near the end of the river (a 24 m (79 ft) drop).
