The east channel and the Jack River flow from the southeast portion of the lake into Little Playgreen Lake then the Nelson east channel continues in a northerly direction passing through Pipestone Lake on its way to Cross Lake. The west channel flows out of the north ends of Playgreen Lake, Kiskittogisu Lake and Kiskitto Lake into Cross Lake at the Manitoba Hydro's Jenpeg Generating Station and Dam. From Cross Lake it flows though Sipiwesk Lake, Split Lake and Stephens Lake on its way to the Hudson Bay.〔(【引用サイトリンク】 url = http://www4.rncan.gc.ca/search-place-names/unique/GAVWD )〕〔(【引用サイトリンク】 url =http://atlas.nrcan.gc.ca/site/english/toporama/index.html )〕 Since it drains Lake Winnipeg, it is the last part of the large Saskatchewan River system, as well as that of the Red River and Winnipeg River. Devils Lake is unusual for a glacial lake in being presently closed, also has been known to overflow into the Red River for at least five separate periods since deglaciation.〔(Comments on Statements by North Dakotas Senator Kent Conrad in His Letters to the Great Lakes Commission Regarding the Commission’s January 23, 2003, Letter to Senators Urging Support of Senator McCain’s Amendment on the Devil’s Lake Outlet in the Omnibus Appropriations Bill for Fiscal Year 2003 )〕 Besides Lake Winnipeg, its primary tributaries include the Grass River, which drains a long area north of Lake Winnipeg, and the Burntwood River, which passes through Thompson, Manitoba. The river flows into Hudson Bay at Port Nelson (now a ghost town), just north of the Hayes River and York Factory. Other communities upriver from there include Bird, Sundance, Long Spruce, Gillam, Split Lake, Arnot, Cross Lake, and Norway House. 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「Nelson River」の詳細全文を読む スポンサード リンク
