Deep River is a river located in the Great Southern region of Western Australia. The river is under tidal influence for the last of its length. Although generally shallow the Deep River has depths of up to in places. The Deep River is one of the few perennial rivers in Western Australia although 80% of its discharge occurs in winter and spring. The rivers water quality is very good, fresh and low in nutrients. The majority of the catchment of the Deep River is not cleared. The silt and clay content can be high during the winter period. The Deep River begins just west of Lake Muir about 50 km from the coast on the edge of the Yilgarn Plateau. It flows through a valley between granite hills then wanders across the coastal plain finally entering the Nornalup Inlet on the western side. The two tributaries of the Deep River are the Weld River and Croea Brook. Some features of the river include wide unobstructed pools interspersed with rapids such as Rowell’s Pool and two waterfalls, Fernhook Falls and Gladstone Falls. 〔(【引用サイトリンク】title=Walpole Wilderness Proposal )〕 The Deep River flows through forested areas of National Park including the Walpole-Nornalup National Park before discharging into the Nornalup Inlet. Originally sighted in 1831 by Captaian Thomas Bannister, he river was not named until 1841 by the Colonial Secretary, Peter Brown. It had been known as the Frankland River by sealers that operated in the area. The explorer W.N. Clark named it West River on his charts but Brown later decided on the current name. ==References== 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「Deep River (Western Australia)」の詳細全文を読む スポンサード リンク
