After 1 month! Qiangpi brought 287 mm of rainfall, and the water storage rate of Shimen Reservoir returned to 100%

The water storage rate of Shimen Reservoir is full, and the reservoir area presents beautiful lakes and waters.

The cumulative rainfall in the catchment area during Typhoon Qiangbi reached 287 millimeters. The Northern District Water Resources Branch of the Water Resources Department of the Ministry of Economic Affairs stated today (25th) that as of 8 a.m., the water storage rate of Shimen Reservoir had returned to 100%. The last time the reservoir was full was September 27.

The Northern District Water Resources Branch pointed out that during the typhoon, the cumulative rainfall in the catchment area reached 287 millimeters, with a total inflow of approximately 95 million cubic meters and a cumulative outflow of 79 million cubic meters. Flood control operations were carried out through real-time water monitoring and hydrological forecast information, which effectively reduced the discharge volume by approximately 16 million cubic meters. This not only reduced flood pressure on downstream rivers, but also maintained the stability of regional water supply.

During Typhoon Qiangbi, the Beishui Water Management Bureau continued to monitor the inflow and sediment movement of the reservoir, and started the Amping anti-siltation tunnel at 8 a.m. on the 23rd to carry out siltation operations. About 200,000 cubic meters of silt pre-stored in the siltation tank was discharged into the sea. A total of 670,000 cubic meters of silt were flushed 4 times this year, which conforms to the design function of the anti-siltation tunnel and reflects its function of preventing siltation and extending the life of the reservoir. In addition, the water storage rate of Shimen Reservoir has increased to 100% at 8 a.m. today, completing the post-typhoon storage goal. The current water conditions are good and can provide a stable supply of water for people's livelihood and industry.

Guo Yaocheng, deputy director of the North Water Resources Department, pointed out that during Typhoon Qiangbi, the North Water Resources Department, in addition to monitoring the weather and reservoir inflow changes 24 hours a day, also discussed water release operations with the New Taipei City Government Water Conservancy Bureau, the Taipei City Government Water Conservancy Engineering Office and the Tenth River Branch of the Water Resources Department through video on the 22nd. The method focuses on avoiding the high tide level of the river mouth to reduce the risk of damage to the high flats downstream. At the same time, we discuss the stable water supply strategy with the District 2, District 3 and District 12 management offices of Taiwan Water Company. With full cross-agency cooperation, we can achieve the goal of no reservoir water damage in the river and maintain normal water supply.

The Beishui Water Management Bureau reminds that the inflow is still abundant in the near future, and the reservoir will continue to release water to adjust the water level of the reservoir based on rainfall and real-time water conditions. It calls on the public to pay attention to the broadcast or avoid entering the river area as much as possible to protect the safety of their lives and property.

During Typhoon Qiangbi, the Bei Shui Water Management Bureau continued to control the inflow and sediment movement of the reservoir to ensure that the life of the reservoir was extended.
