The Big Dam over the Jade Lake is narrowly set in the canyon. It divides the Sand River into two parts, with one of them forming a man-made lake. The dam is 100.5 meters high and 130 wide; the bottom is 52 meters wide while the top is 4.5 meters in width. It is considered as “No. 1 Dam in the world” because it is the highest arch dam made of stones. The arch shape design is not only pleasing to the eyes but also enhances its stability. Resting across the lake like a huge dragon, it ranks among the top few dams in the world. With an area of 165 square kilometers in total and reservoir volume of 20 million cubic meters, it is not only an unusual great construction in Chinese architecture but also a significant achievement made by Jiaozuo people.
In the middle of its top, there are seven curvy weirs, each being eight meters wide. Over the weirs, there is an arch truss bridge, the lower reaches of which lie eight huge Chinese characters, meaning to describe the magnificence of the great dam as well as the beauty of the surrounding mountains and rivers. Each of them is three cubic meters in size, conspicuous and dazzling. Moreover, there is also the spectacular waterfall sight, formed by the overflowing flood during the rainy reasons. The waterfall dashes to the 100-meter-deep canyon like a silver flash of light, hitting the rocks violently and stirring thousands of water drops which shine brilliantly in the sun. The scenery looks like a colorful rainbow, marvelous and splendid. |
