The Ma'an Dam ('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 16.3m (53.5feet) high and 229.5m (753feet) long, storing up to 965000m2 in its reservoir. The service spillway of the dam consists of nine gates with a combined capacity of 6380m3/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]
