On December 12, 2014, the first phase of the South-to-North Water Diversion Project's central route was officially completed. By 8 am on May 13, the water level in front of the sluice gate of the Taocha Canal Headworks had reached 159.28 meters (National Elevation Benchmarks of 1985) while 147.61 meters behind the gate, with a water-level difference of 11.67 meters and a flow volume of 351.71 cubic meters per second, surpassing its target of 350 cubic meters per second. Since December 12, 2014, a total of 38.006 billion cubic meters of water has been transferred, the amount of which is equivalent to that of more than 2 thousand West Lake in Hangzhou.

2014年12月12日，南水北调中线一期工程正式通水。截至昨日8时，陶岔渠首引水闸闸前水位159.28m（85高程），闸后水位147.61m，水位差为11.67m，入渠流量351.71m³/s（目标流量350m³/s）。自2014年12月12日通水以来，累计输水380.06亿m³，相当于向北方搬运了2000多个西湖的水量。

Over the past six years, the water quality of the Danjiangkou Reservoir has always maintained above the standard of China's Environmental Quality Standard for Surface Water (Type II), meeting the requirements of water diversion. The proportion of water flowing into the main canal that meets the standard of China's Environmental Quality Standard for Surface Water (Type I) has increased from 21.6 percent five years ago to more than 82.2 percent at present, an increase of more than 60.6 percent, showing an improving trend in water quality.

据了解，南水北调中线工程通水六年来，丹江口水库水质持续稳定在地表水环境质量标准Ⅱ类以上，符合调水要求。其中，流入干渠一类水质比重，已从五年前的21.6%提升至当前的82.2%以上，增幅超过60.6%，丹江口水库水质持续向好。（中文来源/大河网 翻译/赵汉青 审校/白玉杰）
