Authorities in Yeoncheon County have issued flood warnings for the Imjin and Biryong bridge areas as water levels at Gunnam Dam rise [1, 2].

The situation is critical because the dam is approaching its limit, posing a potential risk to infrastructure and residential areas in northern Gyeonggi Province if water levels continue to climb.

As of 9:30 p.m. Tuesday, the water level at Gunnam Dam reached nearly 35 meters [1]. This level is significantly higher than normal, though it remains below the dam's maximum limit of 40 meters [1].

The rise in water levels follows a period of increased rainfall in northern Gyeonggi. While rain began to subside during the afternoon, the water levels remained high [1].

To manage the volume, the Gunnam Dam situation room is regulating the water by releasing amounts similar to the inflow. Approximately 6,700 tons of water per second are flowing into the dam [1]. Reports on the discharge volume vary, with some sources stating the release is roughly 6,700 tons per second [1], while others indicate a higher rate of approximately 7,100 tons per second [2].

Local authorities continue to monitor the Imjin and Biryong bridge areas where the flood warnings remain active. The situation room is maintaining a balance between inflow and outflow to prevent the dam from exceeding its capacity, a measure intended to stabilize the surrounding river systems.

"The rain that was falling in northern Gyeonggi subsided in the afternoon, but the water level remained high," a reporter said [1].

“The water level at Gunnam Dam reached nearly 35 meters.”

The proximity of the water level to the dam's operational limits indicates a high-stress period for regional water management. Because the dam is acting as a buffer for the Imjin River basin, the continued issuance of flood warnings for downstream bridges suggests that the system is operating at near-maximum capacity, leaving little margin for additional unexpected rainfall.
