The Cedar River is a river in the U.S. state of Washington. About long, it originates in the Cascade Range and flows generally west and northwest, emptying into the southern end of Lake Washington. Its upper watershed is a protected area called the Cedar River Watershed, which provides drinking water for the greater Seattle area. The Cedar River drains into Puget Sound via Lake Washington and the Lake Washington Ship Canal. ==Course== The Cedar River originates in the Cascade Range near Abiel Peak, Meadow Mountain, and Yakima Pass, along the King and Kittitas countyline. Several headwater streams join in the high mountains fed from glacial run-off, then the Cedar River flows generally west. It is impounded in Chester Morse Lake, a natural lake that was dammed in 1900 for use as a water storage reservoir. The Rex River joins the Cedar in Chester Morse Lake, as do the two forks of the Cedar River, the north and south forks.〔(Cedar River Watershed Environmental Overview ), HistoryLink Essay.〕 Below Chester Morse Lake, the Cedar River flows through a smaller lake called Masonry Pool. Below Masonry Pool, the Cedar River flows by two former railroad sites, Bagley Junction and Trude. The river then exits the Cedar River Watershed at Landsburg where pipelines route water to the Seattle area. Below the Cedar River Watershed area, the river flows west and north, past the cities of Maple Valley and Renton. At Renton, the Cedar River empties into the southern end of Lake Washington. Its waters eventually enter Puget Sound via the Lake Washington Ship Canal.〔General course info from 〕 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「Cedar River (Washington)」の詳細全文を読む スポンサード リンク
