The dam Imha is a dam with hydroelectric power plant in the province of North Chungcheong , South Korea . It dams the Banbyeon , a tributary of the Nakdong , to a reservoir. The associated power plant has an installed capacity of 50  MW . Andong town is about 10 km downstream .

The dam was built between 1984 and 1992. In addition to generating electricity, it is also used for flood protection and drinking water supply. The power plant is owned by Korea Water Resources Corporation (K-Water).

Barrier structure

The barrier structure is a stone embankment dam with a height of 73 m. The length of the dam crest is 515 m and its width 10 m. At the base of the foundation , the dam is 200 m wide. The volume of the structure is 2.99 million m³. The flood relief is on the left side of the dam.

Reservoir

With a normal storage target of 163 m above sea level , the reservoir extends over an area of ​​around 26.4 (or 31) km² and holds 595 million m³ of water.

The Imha reservoir was connected to the neighboring reservoir of the Andong dam by a tunnel (length 1925 m; diameter 5.5 m). The tunnel is at a height of 141 m above sea level, so that the water can basically flow in both directions. The aim of the tunnel is to ensure that less water at the Imha dam, when there is a strong inflow into the reservoir, has to be diverted unused via the flood relief, by diverting it to the larger Andong reservoir in this case.

power plant

The power plant has an installed capacity of 50  MW . The two machines in the power plant each have a maximum output of 25 MW. The machine house is on the right-hand side at the foot of the dam.
