The Attawapiskat River is a river in Kenora District in northwestern Ontario, Canada that flows east from Attawapiskat Lake to James Bay.〔 Shows river course.〕 ==Course== The Attawapiskat River travels a distance of , and has a drainage area of .〔 The source of the river is Attawapiskat Lake at an elevation of . The main rivers flowing into the lake that are thus part of the Attawapiskat River drainage basin are the Marten-Drinking River, the Otoskwin River and the Pineimuta River. There are two outflows from the Attawapiskat Lake into the Attawapiskat River: a southern and a northern channel. The southern channel is named by the Atlas of Canada as the Attawapiskat River, and is the source location listed in the Infobox at right. The northern channel is named by the Atlas of Canada as the North Channel, and is the more easily navigated route for canoeing. The North Channel outflow from Attawapiskat Lake is at 〔Atlas of Canada Toporama Map Sheet 43D4〕 and consists of two short streams that lead into Windsor Lake. The elevation of the river drops significantly along these two outflow channels, descending from the higher ground of the Canadian Shield to the flatter and more boggy Hudson Bay Lowlands. After a series of rapids, the North Channel rejoins the Attawapiskat River (the southern channel) at 〔Atlas of Canada Toporama Map Sheet 43D3〕 at an elevation of . The river continues east, and makes a bend to the north at Pym Island at 〔Atlas of Canada Toporama Map Sheet 43D〕 at an elevation of . The Streatfeild River joins from the right at an elevation of , and the outlet river from McFaulds Lake, centre of the Northern Ontario Ring of Fire geological area, joins from the left further downstream at 〔Atlas of Canada Toporama Map Sheet 43C〕 at an elevation of . Further downstream, the river then heads east once again. The Mukutei River joins the Attawapiskat from the left at 〔Atlas of Canada Toporama Map Sheet 43F〕 at an elevation of , and the Missisa River joins from the right further downstream at 〔 at an elevation of . At 〔Atlas of Canada Toporama Map Sheet 43B〕 at an elevation of the Lawashi Channel begins and takes part of the Attawapiskat’s flow into the Lawashi River at a point upstream of that river’s mouth at James Bay.〔 The mouth of the Lawashi River is approximately southeast of the mouth of the Attawapiskat.〔 After the Lawashi Channel branching, the main river continues east, past the community of Attawapiskat upstream from the mouth,〔 and exits into the James Bay at the Akimiski Strait, across from Akimiski Island.〔 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「Attawapiskat River」の詳細全文を読む スポンサード リンク
