South Korean authorities lift a flood warning for the Imjin River near the inter-Korean border after water levels begin to fall following heavy rainfall and apparent upstream releases from North Korea. The Han River Flood Control Office first issues a flood advisory Tuesday as water rises rapidly near the Imjin Bridge in Yeoncheon County, about 60 kilometers northeast of Seoul. The advisory is later upgraded to a full flood warning when the Imjin Bridge water level climbs past the 10-meter threshold, rising by fractions of a meter every 10 minutes amid downpours. The environment ministry says satellite imagery taken Monday confirms North Korea’s release of water from the Hwanggang Dam on the upper reaches of the Imjin River without prior notice. As the event develops, water levels at Pilseung Bridge, the northernmost point of the Imjin River in South Korea, also surpass flood management levels. By early Wednesday, the Han River Flood Control Office withdraws the warning for Imjin Bridge after the water level peaks and recedes, measuring about 7.72 meters at 6 a.m. after having reached about 11 meters earlier. Authorities also report Pilseung Bridge levels decreasing to around 6.06 meters by 6 a.m.
