Water released from Mingde reservoir after typhoon brings it to capacity

Water released from Mingde reservoir after typhoon brings it to capacity

2023-08-06

Mingde Reservoir in Miaoli County reached 99% capacity, after Typhoon Khanun brought heavy rainfall throughout Taiwan. It got so full that authorities opened its gates and discharged water over the weekend. Meanwhile, Taiwan’s largest reservoir, Zengwen Reservoir in Tainan, reached nearly half capacity, after being dangerously low only a week ago. With the high likelihood of more storms in the current typhoon season, authorities say the outlook is good for the country’s water supply.

Water rushes through the dam at Mingde Reservoir, after two spillway gates were opened to discharge water.

Typhoon Khanun brought heavy rainfall which filled Miaoli’s Mingde Reservoir to 99% capacity. Concerned that another sudden rain storm would flood the reservoir, authorities discharged water from it on Saturday afternoon. The water was released at a rate of five cubic meters per second, or 18,000 tons of water per hour.

We will still prioritize the irrigation needs of farmers, and will keep an eye on the water-resources situation. If it looks like it’s going to rain, then we will lower the water level to 95% capacity.

By 10 p.m. on Sunday, the reservoir is expected to be at 97.82%. The Irrigation Agency is also urging residents living downstream from the reservoir to remain alert, to prevent accidents caused by the water discharge.

Meanwhile, a catchment area upstream from Tainan’s Zengwen Reservoir has also risen due to continuous rainfall over the mountains of Chiayi, bringing plenty of water into the reservoir in the brevity of just two days.

As of 9:00 this morning, Zengwen Reservoir was at 46.7% capacity; that’s about 236 million tons of water. These past few days of continuous rainfall has brought around 330 millimeters of rain.

The water that was added to the reservoir raised the level from just over 10% capacity to nearly 50% at present.

Southern Region Water Resources Office
It’s been raining continuously around the catchment area. This amount of rainfall is very good for the situation at the reservoir.

While Zengwen Reservoir is now near half-capacity, nearby Nanhua Reservoir is already full following heavy rainfall brought by Typhoon Doksuri last week. With typhoon season still in full swing, authorities say the outlook for water resources is good.

卡努灌飽明德水庫 曾文水庫近半滿 蓄水量達2.36億噸

2023-08-06

受到卡努颱風外圍環流影響,明德水庫蓄水率一度達到99%,5日下午,實施調節性洩洪,目前預計先將蓄水率下降到95%,來配合農民灌溉用水,接著將視氣候狀況,來因應調整。另外,位於嘉義縣大埔鄉,全台蓄水量最大的曾文水庫,雖然還沒喝飽,但連續3天降雨超過300毫米,蓄水量來到2.36億噸,加上阿里山鄉、番路鄉等上游山區持續下雨,今天最新的蓄水率,正往50%大關邁進。

明德水庫,大水向下流動,兩道閘門同時開啟,實施大量洩洪。

受到卡努颱風外圍環流影響,明德水庫蓄水率,一度達到99%,就怕雨勢來得快,5日下午4點半,實施調節性洩洪,以每秒5立方米釋放水量。

[[農田水利署苗栗管理處副處長 翁志成]]
“我們還是以目前需要灌溉農民的灌溉用水為優先,會看水情啦,如果會有下雨的機率的時候,我們大概會下降到95%的部分”

截至6日上午10點,明德水庫蓄水率,高達97.82%,農田水利署也呼籲,下游居民,提高警覺,以免發生意外。

不只明德水庫水位直直升,曾文水庫的上游集水區,也因為嘉義山區連續大雨,在短短兩天內大進帳。

“今天早上九點的蓄水率是46.7%,蓄水量大概是2.36億噸左右的蓄水量,這幾天的持續降雨,大概330毫米降雨量”

[[大埔鄉長 吳明勳]]
“這次水量的挹注,從十幾趴的容量,現在快突破50%大關”

[[聲源:南水局副局長 何達夫]]
“因為集水區持續在降雨當中,這樣的降雨量,對整個水庫的水情是很有幫助的”

只曾文水庫大進帳,上次杜蘇芮颱風掃過南台灣,早就喝飽的南化水庫,而目前正值颱風季,南水局樂觀看待水情。
