Taiwan's reservoirs receive over 500 million tons of water from seasonal rains

Taiwan's reservoirs are experiencing a substantial water replenishment thanks to the ongoing plum rain season and southwest monsoons. As of June 13, 2026, statistics from the Water Resources Agency indicate that the total inflow into the island's main reservoirs is projected to exceed 500 million tons.

The southern region has seen particularly significant gains. The Zengwen and Wushantou reservoirs, combined, have received over 120 million tons of water, making them the largest beneficiaries. Other key reservoirs also show substantial increases: Shimen Reservoir has gained 75.9 million tons, Nanhua Reservoir 64.5 million tons, and reservoirs in the central region like Sun Moon Lake and Deji have each received over 40 million tons.

This influx of water is a welcome development, especially for areas like Hsinchu, which faced tight water conditions earlier in the year. The Baoshan and Baoshan No. 2 reservoirs in Hsinchu are now at 100% capacity. The Zengwen Reservoir, previously at single-digit storage levels, has now risen to over 22% capacity and is aiming for 30%, while Wushantou is at 26.8% and Nanhua at 63.1%.

Economic Affairs Minister Kung Ming-hsin expressed satisfaction with the improved water situation in the south, emphasizing that current supplies are secured through September even without further rain. This significant replenishment eases concerns about potential water shortages and bolsters the island's water security.
