North Korea Opens Dam Flow, Sweeping Away 6 in the South
Officials said the Imjin River’s water level on the border doubled, to 15.1 feet, after North Korea began releasing water without warning at 2 a.m. on Sunday, either from its newly built Hwanggang Dam 17 miles north of the border or from a smaller dam downstream.
There is a good chance, that the flooding was unintentional, given that the dam was newly built. North Korean obviously would not want to reveal their shoddy engineering and/or management errors and thus would have to claim that the flooding was intentional.
