It was 1986. Preparations were under way for South Korea’s coming-out party – The 1988 Seoul Olympics. And on the other side of the demilitarized zone (DMZ), North Korean began preparations of their own, breaking ground for a dam to be built on the Bukhan River, a short 19 kilometers from the border. Completed in 2003, it is called the Imnam Dam.
Perhaps fears of North Korean terrorism during the South Korean Olympics were top of mind for South Koreans, so they began to imagine the worst. As the New York Times explained in an article in 2007, then President Chun Do-hwan did imagine a scary scenario – the new dam in the North producing a monstrous flood, pounding waters headed straight for the South.
In response to the so-called water-bomb scare, South Korean television networks broadcast artists’ conceptions of monstrous walls of water unleashed from the North Korean dam, wiping out most of Seoul, 120 miles downstream, with the impact of a nuclear explosion during the Olympics.
A year later, in 1987, the fears were too hard to resist, and the South Korean government gave the green light to their own dam project, today called the Peace Dam. Located about 16 kilometers from the border to the north, the Peace Dam took a while to build, and in fact was finally completed in 2005, seven years after the Seoul Olympics. But it stands today, 125 meters high and 600 meters wide. There is actually no reservoir at the Peace Dam. Its sole purpose is to be peace of mind – a wall just in case the feared flood from the North ever comes racing down the Bukhan River – peace of mind in this case that cost USD429 million.
It actually seems like a bit of expensive folly, and to be fair, the South Korean government suspended construction work on the dam after a few years. But when satellite photos apparently showed signs of cracks in the Imnam Dam in the North, fears of the deluge arose anew in the imaginations of the leaders. Work resumed, and the Peace Dam was finished.
Actually, it is another dam in North Korea that is causing grief – The Hwanggang Dam on the Imjin River, which is 42 kilometers from the DMZ. Over the past several years, there have been 8 cases where North Korean officials released massive amounts of water, causing significant flooding in South Korea. It’s not the “nuclear explosion” impact that was feared in the 1980s, and yet 6 South Koreans were killed when water was released from the Hwanggang Dam in September 2009.
The South and the North have an agreement that the North would provide notice to the South when they intend to release dam waters, commonly after significant rainfall, but in practice, the North Koreans rarely do.
In the end, should they have bothered building the Peace Dam? I guess one could say that they were dam-ed if they did, and dam-end if they didn’t.
“Like the two Koreas, the two dams are twin brothers, born at the same time, facing each other across DMZ,” said Lee Tae-ik, an official at Korea Water Resources Corporation, which maintains the South Korean dam. “The Peace Dam is an inevitable child of a divided nation.”
