Taiwan's Zengwen Reservoir Recovers Dramatically from Drought, Nearing 300 Million Cubic Meters Capacity

Southern Taiwan's water situation has undergone a remarkable turnaround, with the Zengwen Reservoir, the island's largest, now approaching a storage capacity of 300 million cubic meters. This surge follows a period of severe drought that saw the reservoir's water levels plummet to critical lows earlier in the year.

In early June, the Zengwen Reservoir's storage rate dipped below 10%, reaching a year-low of 9.4% on June 5. At that point, it held only 42.12 million cubic meters of water, exposing large areas of the reservoir's bottom and sparking widespread concern about potential water rationing in southern Taiwan.

However, favorable weather conditions in mid-June brought a series of heavy monsoon rains directly to the reservoir's catchment area. Although Typhoon Mikala did not make direct landfall, its strong southwest airflow and trailing effects delivered substantial rainfall over several consecutive days. This sustained influx of water has dramatically boosted the reservoir's levels.

In a span of just one month, the water storage has surged from 42.12 million cubic meters to nearly 300 million cubic meters as of July 5. This represents an increase of over 250 million cubic meters, effectively ending the immediate threat of a water crisis.
