Tsengwen Reservoir Water Level at 30% 枯水期降雨偏少 曾文水庫蓄水率不到3成

Tsengwen Reservoir is the largest in the country and now it had dried up to less than 30 percent capacity.


Taking advantage of the weather, personnel from Tsengwen Reservoir quickly deployed artificial rain-enhancing flames, hoping to bring more water to the catchment area. However, the results were limited. A large area of soil that was originally in the water at Tsengwen Reservoir can already be seen. The water level is less than 207 meters. Upstream rainfall is relatively low recently, due to the dry season. Tsengwen Reservoir, the largest reservoir in the country, has seen its water storage rate fall below 30 percent.

Ho Ta-fu, Deputy Director, Southern Region Water Resources Office: “The amount of water has decreased at the Tsengwen and Wushanto Reservoir systems due to irrigating autumn-winter crops and the lack of rainfall.”

Tsengwen Reservoir has fully allocated its water for agriculture. As for the Nanhua Reservoir, which mainly supplies water for households, its water storage rate is less than 90 percent. The Southern Region Water Resources Office controls the daily water outflow. If the situation permits, it will divert water from another region. Currently, the water supply is stable until the end of February next year.

Ho Ta-fu, Deputy Director, Southern Region Water Resources Office: “We will utilize one of the remaining streams of the Kaoping River to enhance the entire Kaohsiung area to send water north to support Tainan. That will be 200,000 cubic meters per day. And we will control the daily water outflow of Nanhua Reservoir to below 500,000 cubic meters.”

Citizen: “You can reuse rice-washing water and floor-mopping water. A plastic bottle filled with water placed in the toilet can help reduce the amount of water used to flush the toilet.”

People have their own set of water-saving measures, but in fact, because it has entered the dry season, Tainan is the only county in the country that has a green light reminding people to properly conserve water resources.

 

 

趁著天氣允許,曾文水庫的人員趕緊施放人工增雨的燄劑,盼能夠為集水區多點水,但成果有限。來到曾文水庫大壩,已經可以看到原本水裡的泥土露出一大片,而水位標高也不到207公尺。近期因為進入枯水期,上游降雨偏少,國內最大的水庫曾文水庫蓄水率已經低於3成。

南區水資源局副局長何達夫說道:「第一個是曾文烏山頭水庫系統農業用水部分,在2期作跟秋冬雜作配合作物生長,跟現地降雨狀況,適時延長間段供灌的頻率,來降低水庫的出水量。」

主要供應農業工業用水的曾文水庫,全力調配農業用水調度,至於供應民生用水為主的南化水庫,蓄水率也不到9成,南水局也管控每日出水量,而情況許可下,也會啟動甲仙攔河堰,進行越域引水,目前民生、產業用水可穩定供應至明年2月底。

南區水資源局副局長何達夫指出:「利用高屏溪剩餘的一個川流水,來提升整個高雄地區,清水北送支援台南,每日20萬立方公尺,落實每日南化水庫,出水量管控,在50萬立方公尺以下。」

民眾提及:「洗米水,然後拖地水,都可以做重複的使用,馬桶中放入裝水的寶特瓶,讓馬桶沖水的水量減少。」

民眾也有自己的一套省水招式,不過事實上由於已進入枯水期,台南更是國內唯一亮起「水情提醒」綠色燈號的縣市,除了公部門努力調配水資源外,也呼籲各界須妥善運用水資源。
