A severe drought and heat wave have caused water levels in South Korea's Okjeongho reservoir to recede significantly [1].
The decline in water levels threatens the agricultural supply for the Honam plain, a critical farming region in the southern part of the country [2].
Observations from mid-April 2024 showed the lakebed becoming exposed as the water retreated [1]. The reservoir, located on the Seomjin River, serves as a primary water source for the surrounding region [2].
Kim Young-mok, the Korea Water Resources Corporation Seomjin River Dam Operations Manager, said the water level is approximately 10 meters lower [1] than the average level.
Local residents and officials have expressed desperation for precipitation. Some said they are hoping for a typhoon to bring the necessary rainstorms to refill the reservoir [1].
The drought has reduced the inflow of water into the dam, leaving the area vulnerable to continued water shortages. In mid-April 2024, reporter O Jeom-gon noted that Bungeo Island, known for resembling a crucian carp, remained visible as the surrounding waters dropped [1].
Water management staff continue to monitor the Seomjin River Dam as the region waits for a shift in weather patterns to alleviate the dry conditions [2].
“The water level is approximately 10 meters lower than the average level.”
The significant drop in Okjeongho's water levels highlights the vulnerability of South Korea's agricultural infrastructure to extreme weather. Because the Honam plain relies heavily on this specific reservoir for irrigation, prolonged deficits can lead to crop failure and increased food price volatility in the region.
