A prolonged drought in South Korea's Yeongnam region has reduced the Unmun Dam reservoir to approximately 25% of its total capacity.
The water shortage threatens the food security of the region and the stability of domestic water supplies for residents in several major cities.
The crisis is most acute in Gyeongsangnam-do, Cheongdo, Gyeongsan, and Daegu [1, 2]. At the time of reporting, the water level at the Unmun Dam sat at 24.7% [1]. This represents a sharp decline compared to the same period last year, when the reservoir was at 63% [1].
Agricultural sectors are bearing the brunt of the depletion. In Gyeongsangnam-do alone, 2,121 hectares of farmland have been affected by the lack of irrigation water [1]. Farmers in the region are facing severe difficulties maintaining crops as the drought persists, leaving reservoirs unable to meet basic agricultural demands.
Local authorities said the crisis may extend beyond the fields. While the current focus remains on agricultural water, there is a looming risk to the domestic water supply for the general population [1, 2]. The dwindling levels at the Unmun Dam are creating a precarious situation for the surrounding municipalities that rely on the reservoir for daily life.
Regional officials said they are monitoring the situation as the gap between current levels and historical averages continues to widen. The disparity between the current 24.7% capacity and last year's 63% underscores the severity of the current weather pattern [1].

The drastic drop in reservoir levels indicates a systemic failure of seasonal rainfall in the Yeongnam region. Because the Unmun Dam serves as a critical hub for both irrigation and municipal use, the transition from an agricultural crisis to a public health crisis is a significant risk if precipitation does not increase soon.
