Dajia River (Chinese: 大甲溪; pinyin: Dàjiǎ Xī; Pe̍h-ōe-jī: Tāi-kah-khoe; literally: "big shell river") is a river in north-central Taiwan. It flows through Taichung City for 124 km. The sources of the Dajia are: Hsuehshan and Nanhu Mountain in the Central Mountain Range. 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.

The Deji Reservoir (德基水庫; Déjī Shuǐkù; "virtuous foundation reservoir"), formed by Techi Dam, is a 592-hectare reservoir in Dajia District. The reservoir provides municipal water, generates hydroelectric power, is used for recreation and prevents flooding. 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. The other five dams in sequence from top hill are Qingshan Dam, Kukuan Dam, Tienlun Dam, Ma'an Dam and Shihgang Dam.
