context_page_description: Hwacheon Dam is a concrete gravity dam on the North Han River in Hwacheon County, Gangwon-do Province, South Korea. The dam was completed in 1944 as a primary source of electricity in southern Korea. It was the focal point of a raid during the Korean War and also provides flood protection from North Korea's Imnam Dam upstream.
context_section_description: The dam is a 78 m (256 ft) tall and 435 m (1,427 ft) long concrete gravity-type. The dam sits at the head of a 3,901 km² (1,506 sq mi) catchment area and its reservoir has a gross capacity of 1,018,000,000 m³ (825,306 acre⋅ft). Of this capacity, 809 million m³ can be regulated and 213 million m³ is used for flood control. The reservoir's surface area is 38.9 km² (15 sq mi). The dam's spillway is controlled by 16 sluice gates and has a maximum discharge capacity of 5,428 m³/s (191,688 cu ft/s). The dam's power station is located 2.5 km (2 mi) southwest of the dam at 38°05′56″N 127°45′44″E, just over a ridge. The power station contains four 27 MW turbine-generators and has an effective hydraulic head of 74.5 m (244 ft).
