Overview

• Obong Reservoir fell to 13.2 percent Friday, a new low, with levels declining by roughly 0.3 to 0.4 percentage points each day.
• Starting Saturday, the city will shut supply to 123 large sites — including 113 apartment complexes and 10 lodging facilities — and refill their tanks by tanker truck.
• A national surge operation is underway with 71 fire trucks, about 800 troops and roughly 400 military tankers, 10 helicopters, and a 5,000‑ton Coast Guard ship that delivered around 600 tons.
• Authorities funneled 26,416 tons Thursday and plan 29,792 tons Friday via trucks, pipelines and air drops, yet officials say the sub‑10 percent threshold could be reached within days.
• Gangneung is distributing about 2.47 million bottles of water and preparing timed nightly supply, with alternate‑day rationing as the next step if levels deteriorate further.
