The Zengwen Reservoir, the largest in the country, was originally full, but there has been no abundant rainfall in the catchment area for more than a month. The upstream revenue is not obvious, and it continues to provide irrigation for the second phase of rice cultivation. The water storage rate has dropped by more than 5% in 10 days, but the effective water storage capacity is still the highest in Taiwan.
According to statistics from the Water Resources Branch of the Southern District of the Water Resources Department, the Zengwen Reservoir catchment area has not experienced abundant rainfall since September 6. Only on September 15, the cumulative rainfall was 12.1 millimeters. The rest were only single digits, not even a drop fell. There was no water inflow from the upstream, and water had to be released to assist agricultural irrigation. The water storage rate began to decline.

The Zengwen Reservoir entered October with a full water level of 230 meters above sea level. Due to the need to supply the second phase of rice irrigation, the water release operation was started and the water was diverted to the Wushantou Reservoir for storage and utilization. The South Water Management Bureau stated that the current daily water release volume is about 4 million cubic meters. It is expected to continue until the end of this month, and the water storage rate will drop again, by which time it is estimated to be about 88%.
According to the South Water Administration Bureau, as of noon today, the water level of Zengwen Reservoir was 228.47 meters, with a water storage rate of 94.23%. Together with the total effective water storage capacity of Wushantou Reservoir, it still exceeds 525 million cubic meters; as for the supply to the public The Nanhua Reservoir, which mainly uses domestic water, continues to divert water from Kaohsiung's Chishan Creek through the Jiaxian Barrage. The current water level is 179.78 meters, with an effective water storage capacity of 80.79 million cubic meters and a water storage rate of 98.75%.
The Southern Water Management Bureau pointed out that the current water conditions in the southern region are normal and there is no risk of water supply. Since the time sequence has entered the end of the flood season, the reservoirs are close to being full, which is a good foundation for stable subsequent water supply. However, it still calls on the public to cherish water resources, continue to develop good habits of saving water, and cherish water resources.
