The Ma'an Dam (traditional Chinese: 馬鞍壩; simplified Chinese: 马鞍坝; pinyin: Mǎ'ān Bà, 'Saddle Dam') is a concrete gravity barrage dam on the Dajia River in Heping District, Taichung, Taiwan. The dam is the final stage of a cascade of hydroelectric power plants along the Dajia River and is located below the Tienlun Dam.

Built from 1992 to 1998, the dam is 16.3 m (53 ft) high and 229.5 m (753 ft) long, storing up to 965,000 m3 (782 acre⋅ft) in its reservoir. The service spillway of the dam consists of nine gates with a combined capacity of 6,380 m3/s (225,000 cu ft/s).[1]

The dam supplies water through a tunnel to a 133.47 MW power station near Xinshe with two 66.735 MW turbines, generating 410.2 million kilowatt hours per year.[2]
