Cloud seeding adds 2.8 million tons to Shihmen Reservoir

Cloud seeding adds 2.8 million tons to Shihmen Reservoir

2024-04-01

Cloud seeding brought slight relief to northern reservoirs last Sunday. As storms swept the region, officials launched cloud seeding over the Shihmen and Second Baoshan reservoirs, giving a boost to water supplies. Shihmen Reservoir has gained an extra 2.8 million tons of water so far, enough to supply the area for about three days. Total gains are expected to rise to 4 million tons.

With storms brewing over the weekend, officials carried out cloud seeding in Taoyuan, Hsinchu, and Miaoli, in hopes of bringing relief to reservoirs.

Shihmen Reservoir received roughly 2.8 million tons of rainwater. Given that 1.1 million to 1.12 million tons are used every day, this inflow will provide an additional two or three days of water.

It will take time for more rainwater in the soil to enter reservoirs, officials said. In the end, Shihmen Reservoir is set to gain up to 4 million tons of water. Not only that, recent rains in lowland areas also filled up ponds. Because of this, farmers will be able to draw pond water for rice irrigation, sparing local reservoirs. Officials said the water shortage is well under control.

Water levels are on the low end, but we are far from a critical shortage.

Currently, we are in the second half of the spring dry season. As the seasons change and we enter the rainy season, the plum rain season, the government must prudently address the potential for extreme rainfall brought on by climate change.

Shihmen and the Baoshan reservoirs have dipped below 30% capacity, while Mingde and Liyutan in Central Taiwan are just above 30%. Nantou’s Sun Moon Lake is still at 70%, but its water level is receding fast. In the south, Tsengwen Reservoir stands just above 40%. Confronted with sparse spring rains, the Water Resources Agency has formed a drought response team to handle water sourcing and conservation.

雷雨緩解水情? 北水分署:石門水庫進帳280萬噸

2024-04-01

北部週日狂風暴雨,北水分署也把握雨勢,在石門和寶二水庫,進行人工增雨作業,目前石門水庫進帳280萬噸,增加約3天用水量,預期未來還會再增加,有望達400萬噸,不過今年春雨偏少,水利署還是呼籲民眾要節約用水。

週日豪雨來得又快又急,北水分署把握雨勢,在桃竹苗地區實施人工增雨,希望挹注水庫水量。

“以(石門)水庫的降雨來講,差不多280萬噸。現在一天公共用水,差不多110到112萬噸,這一個部分的話,可能會有2到3天的對水庫的挹注。”

北水分署解釋,土壤水分釋放到水庫,需要一點時間,預期石門水庫整體蓄水量,將增加300到400萬噸。另外, 最近平地下雨,埤塘也有進帳,因此一期稻作改用埤塘水源,暫停從水庫供灌。北水分署表示,一切都在掌握之中。

“確實水量是略微偏少,但是事實上還不是說達到所謂的太過嚴苛。”

[[行政院長 陳建仁(3.28)]]
“目前台灣已經進入了春季枯水期的後半段,在季節交替,進入豐水期梅雨來臨之前,政府需要來審慎因應氣候變遷,導致極端降雨的不確定性。”

目前石門水庫、寶山水庫,蓄水率都跌破3成;中部的明德和鯉魚潭則只有3成出頭。至於南投日月潭蓄水率有7成多,但距離滿水位落差達5米,水位持續下降中;南部曾文水庫則剩下4成多。面對春雨偏少,水利署已成立抗災應變小組,要持續開源節流。
