The Jacques-Cartier River is a river in the province of Quebec, Canada. It is 161 km long and its source is Jacques-Cartier Lake in Laurentides Wildlife Reserve, and flows in a predominantly southern direction before ending in the Saint Lawrence River at Donnacona, about 30 km upstream from Quebec City. It is currently under nomination for Canadian Heritage River status. ==Geography== The Jacques-Cartier River drains an area of 2515 square kilometres, starting in and flowing for nearly 160 kilometers through the Laurentian mountains in the geological region of Grenville (one of the youngest sections of the Canadian Shield, formed 955 million years ago), then flows through the sedimentary rocks of the St. Lawrence lowlands for approximately 17 kilometers, from the municipality of Pont-Rouge to its mouth. The area covered by the drainage basin is for the most part undeveloped or protected, especially its source. In fact, 77% of its length is protected by the Laurentides Wildlife Reserve and the Jacques-Cartier National Park where one finds a steep glaciated valley formed during the last glaciation. Nevertheless, about 25000 people live on the shores of this river close to its mouth, where it crosses the regional municipality of Portneuf and the municipalities of Tewkesbury, Saint-Gabriel-de-Valcartier, Shannon, Sainte-Catherine-de-la-Jacques-Cartier, Pont-Rouge and Donnacona. Important tributaries are: *Rivière aux Pommes (Apple River) *Rivière Sautauriski *Rivière Ontaritzi *Rivière à l'Épaule (Shoulder River) *Rivière Cachée (Hidden River) *Rivière Launière. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jacques-Cartier River」の詳細全文を読む スポンサード リンク
