Although the Qing Dynasty left a lot of historical data, such as "precipitation record", "snow measured", "single grain" and so on, but there is still not able to combine these factors.

虽然有清一代留下了大量的史料，如《晴雨录》、《雨雪分寸》、《粮价单》等，但是目前仍不能把这些因素结合起来。

But below-average precipitation, increased evaporation due to above-average temperatures, and mounting water consumption is driving water levels here to record lows.

但是低于平均水平的降水量，因高于平均水平的温度而升高的蒸发量，以及日益增加的耗水量使得这里的水位创出新低。
