All-out efforts underway to supply water to drought-hit Gangneung in South Korea. Despite efforts to replenish the supply, the reservoir has experienced declining water levels, reaching 12.6 percent as of 11 a.m. Sunday, down 0.3 percentage points from the previous day.

All-out efforts have been underway Sunday to supply water to the drought-hit eastern coastal city of Gangneung, officials said, as it struggles with worsening water shortages.

Helicopters, fire trucks and a Navy vessel were set to be dispatched to supply 29,793 tons of water to Obong Reservoir, the city’s main water source, and the Hongje water purification plant for the day, according to city and Gangwon Province officials.

The government declared Gangneung’s drought as a state of disaster on Aug. 30 after the water storage level of the reservoir, which supplies household water to 180,000 Gangneung residents, fell to a record low of 15.7 percent.
