Meiyu Front Boosts Zengwen Reservoir by 78 Million Tons; Renyi Tan Returns to 30% Capacity

嘉義 (Chiayi) region in Taiwan is experiencing significant rainfall from a stationary front and southwest airflow, leading to a substantial increase in water levels at Zengwen Reservoir and Renyi Tan. The Zengwen Reservoir's catchment area has received 301.3 millimeters of rain since June 4, with an estimated 78 million tons of water added. The highest single-day inflow was 13.93 million tons on June 9.

Renyi Tan, in the Bagua River basin, saw 354 millimeters of rain, with a peak daily inflow of 1.62 million tons and a maximum diversion rate of 25 tons per second. This rainfall has raised Zengwen Reservoir's storage rate from a low of 9.4% to 15.9%, and Renyi Tan's from 19.8% to 31.6%, returning it above 30% capacity. Lantan Reservoir also saw its storage increase from 17.1% to 20.4%.

Despite this welcome replenishment, the Water Resources Agency and related units caution that the overall water situation remains precarious. Zengwen Reservoir currently holds only 71.9 million tons, and Renyi Tan and Lantan combined hold 9.67 million tons. Authorities are still evaluating whether irrigation for the second crop season can proceed as scheduled.
