Tsengwen Reservoir water levels rise after heavy rains
The rain brought by a weather front in southern Taiwan on Tuesday should provide a much needed boost to the water supply at Tsengwen Reservoir, the Water Resources Agency’s South Region Water Resources Office reported Wednesday.
The office estimated that 1 million cubic meters of rainfall fell in the reservoir’s catchment area on Tuesday and will make its way into the reservoir, which was at only 18.28 percent of capacity as of Monday at midnight.
Reservoir capacity had improved to 18.39 percent as of Wednesday afternoon at 3 p.m., but that was still a very low level amid Taiwan’s worst drought in decades and may not be enough to stave heavy water rationing in the area.
Another important reservoir in the Tainan area — Nanhua Res- ervoir — received 50,000 cubic meters of water.
The additional water seen at the two reservoirs was enough to supply household water use for two days, according to the South Region Water Resources Office.
The rainfall in the Tainan area, among the heaviest in the country on Taiwan, also replenished irrigation water on Tainan farms, reducing the need for 2.4 million cubic meters of water for irrigation to be supplied from Tsengwen Reservoir, the office said.
Tainan and Kaohsiung in southern Taiwan are currently facing second-phase water rationing, and have had their water supply cut by 10 percent from normal levels since April 15.
In parts of northern Taiwan, phase-three water rationing has been introduced, cutting off water completely to users for two days a week on a rotating basis.
