South Koreans Retaliate On Irrigation Water Supply in ONGJIN Irrigation water for the KAGEON (870-1690) area is controlled by a reservoir located at HANJAN DONG (840-1701) in North KOREA. The flow of this water was stopped by the North Korean authorities on 27 April (see P/R #622). The water supply for the North Korean reservoir originates from a reservoir at (836-1697) in South KOREA. In an effort to force the North Koreans to release water for irrigation purposes, the ONGJIN (840-1680) District South Korean National Police stopped the flow of water from the South Korean reservoir at 041500 May. This action provoked a border incident at (836-1697) on 04 May which involved approximately twenty (20) North Korean Constabularymen and fifty (50) South Korean police. Approximately forty (40) rounds were fired by both sides, but no casualties were reported. Firing ceased because of darkness, but both sides maintained their positions during the night of 04-05 May. South Korean police placed guards on the Southern reservoir to prevent the Northerners from reopening it. It is estimated that the water supply in the northern reservoir will be exhausted in five days. (CIC Flash report, Police report) COMMENT: This effort by the south may prove successful as the irrigation system filled by the reservoir located in North KOREA supplies water for approximately 20,000 tyung of North Korean land as well as an equal amount of land located south of the parallel. 2.
