逾1個月無豐沛降雨 曾文水庫蓄水率10天減逾5%

Quick Look

曾文水庫因持續供應二期稻作灌溉,蓄水率自滿水位下降10天來減逾5%,目前為94.23%,雖仍為全台有效蓄水量之冠,但預計將持續放水至本月下旬,蓄水率可能降至約88%。南水分署表示南部水情正常,供水無虞,仍呼籲民眾節約用水。

Why It Matters

曾文水庫是國內規模最大的水庫,原本滿水位,但集水區超過一個月無豐沛降雨,上游進帳不明顯,同時持續供應二期稻作灌溉,導致蓄水率下降。

國內規模最大的曾文水庫原本滿水位,但集水區超過1個月沒有豐沛降雨,上游進帳並不明顯,且又持續供灌二期稻作,蓄水率10天減逾5%,但有效蓄水量仍全台之冠。

水利署南區水資源分署統計,曾文水庫集水區從9月6日迄今,集水區就未再出現豐沛降雨,僅在9月15日當天的累積降雨12.1毫米,其餘都僅個位數,甚至一滴都沒下,上游沒有進水,又要放水協助農業灌溉,蓄水率開始下降。

請繼續往下閱讀...

曾文水庫以標高230公尺的滿水位進入10月份,由於要供應二期稻作灌溉,啟動放水作業,引流至烏山頭水庫蓄存並利用,南水分署表示,目前每天放水量約400萬立方米,預計持續至本月下旬,蓄水率會再降,屆時預估約88%。

南水分署觀測,截至今天中午,曾文水庫水位標高228.47公尺,蓄水率94.23%,連同烏山頭水庫的合計有效蓄水量仍逾5.25億立方米;至於供應民生用水為主的南化水庫,持續透過甲仙攔河堰,從高雄旗山溪進行越域引水,目前水位標高179.78公尺,有效蓄水量8079萬立方米,蓄水率98.75%。

南水分署指出,現階段南部地區水情正常、供水無虞,因時序已進入豐水期末,各水庫接近滿庫,是穩健後續供水的良好基礎,但仍籲請民眾珍惜水資源,持續養成節約用水的好習慣,珍惜水資源。

Hong Kong to expand community recycling after shelving waste-charging scheme

Farmer Huang Jinyang of Sanzhou Village, Changting County, Fujian Province has been planting trees on red soil for 40 years since 1986. By contracting barren hills to plant bayberry and tea trees, he has achieved water and soil erosion control with policy support and personal persistence, reducing the county's water and soil erosion rate from 31.5% in 1985 to 6.18% by the end of 2025, driving rural revitalization and ecological civilization construction.
