The Nierji Dam is an embankment dam on the Nen River just north of Morin Dawa and on the border of Inner Mongolia and Heilongjiang Province, China. The dam was constructed between 2001 and 2006 for several purposes to include hydroelectric power generation, flood control, navigation and water supply.
The dam is a rock-fill type and 41.50NaN0 tall at its highest point. The total length of the dam is 71800NaN0 which includes the 16760NaN0 long main dam with an asphalt core. The dam creates a reservoir with a capacity of 86100000000NaN0 and sits at the head of a 664000NaN0 catchment area. The dam's spillway consists of 11 floodgates and has a maximum discharge capacity of 203000NaN0. The dam's power station contains four 62.5 MW Kaplan turbine-generators for a total installed capacity of 250 MW.[2]
