Dajia River (Chinese: 大甲溪; pinyin: Dàjiǎ Xī; Pe̍h-ōe-jī: Tāi-kah-khoe; lit. 'big shell river') is the fifth-longest river in Taiwan located in the north-central of the island. It flows through Taichung City for 142 km.[1] The sources of the Dajia are: Hsuehshan and Nanhu Mountain in the Central Mountain Range.[2] The Dajia River flows through the Taichung City districts of Heping, Xinshe, Dongshi, Shigang, Fengyuan, Houli, Shengang, Waipu, Dajia, Qingshui, and Da'an before emptying into the Taiwan Strait.[2]
The Deji Reservoir (德基水庫; Déjī Shuǐkù; 'virtuous foundation reservoir'), formed by Techi Dam, is a 592-hectare reservoir in Dajia District.[3] The reservoir provides municipal water, generates hydroelectric power, is used for recreation and prevents flooding.[3] Techi and a cascade of five other dams on the Dajia produce up to 1,100 megawatts of hydroelectric power and generate more than 2.4 billion KWh per year.[4] The other five dams in sequence from top hill are Qingshan Dam, Kukuan Dam, Tienlun Dam, Ma'an Dam and Shigang Dam.
Taiwan's Central Cross-Island Highway runs along the Dajia River from Heping to Dongshih. The Taichung Beltway begins in Fongyuan and follows the Dajia through into Cingshuei.
Incidents[]
The Dajia experiences frequent earthflows during typhoons and heavy rain, damaging homes and breaking up roads, sometimes permanently.[citation needed] In September 2008, rains from Typhoon Sinlaku resulted in storm-swollen waters which washed away supports for a section of Houfeng Bridge (which links Houli Township and Fengyuan City), leaving six people dead.[5] In June 2010, the bridge finally reopened to vehicular traffic after over NT$1.4 billion of reconstruction work.[6]
