The Han River Flood Control Office lifted a flood warning for Imjin Bridge at 5:30 a.m. on July 22 after water levels began to recede.
The water level at Imjin Bridge stood at 7.72 meters as of 6 a.m. It had peaked above 11 meters the previous day before falling overnight. The level at Pilseung Bridge measured 6.06 meters.
The Environment Ministry attributed the sharp rise to North Korea's release of water from the Hwanggang Dam without prior notice. Satellite imagery taken Monday confirmed the discharge.
A Unification Ministry official urged North Korea to respond jointly to natural disasters in a responsible manner. North Korea agreed in 2009 to notify the South in advance of any dam releases.
