How many years was the original stone inscription in Jiangdu Water Diversion Project built?

Jiangdu Water Control Project is the source of the East Route of South-to-North Water Transfer Project. In 2003, on the occasion of the 40th anniversary of the establishment of the Management Office, a huge stone named "Source" was erected upstream of a station to commemorate it. Qi, Secretary-General of the Water Conservancy Economic Research Association of the Ministry of Water Resources (former Director of the Policy and Regulation Department of the Ministry of Water Resources) wrote an inscription for this purpose. The content is as follows:

Jiangsu is surrounded by Wu Chu, connected with the Central Plains and bordering the East China Sea, while the Yangtze River and Huaihe River run through the east and west. The ancient Grand Canal runs through the north and south, with a pearl of Taihu Lake in the south and many mirrors in the north. However, it is too cold to be low. There are many dangers of sudden floods, and they often encounter changes in cold and warm air currents, hiding the threat of storm surges in landing seas. In the year of the great flood, the Yangtze River and Huaihe River rose together, with violent storms and tides propping up. During the drought season, rivers and lakes dry up and bare land is thousands of miles away, especially in Huaibei. Therefore, there is not much difference between one river and two places.

Gan Kun is determined to build water conservancy projects, and the leaders guide the country and draw a grand plan for the South-to-North Water Transfer Project. Jiangsu is brave as a pioneer. According to the trend of the river, vote for Jiangdu three stations; Undertake the foundation of the canal and expand the northward passage of water; Relying on Hongze Lake, storing and drawing the source; Select nodes along the way to create multi-level water transfer control. For the second time, it was built into four stations with supporting culverts 13. The project started in 196 1 year and was completed in 1977. In the meantime, after three years of natural disasters and ten years of Cultural Revolution, the sons and daughters of Jianghuai decided to swallow mountains and rivers and continue to expand, eventually becoming a tripod. After the restoration and reinforcement of Huaihe River and Taitai River, the hub is perfect.

Viewing Jiangdu hub system leads to the Yangtze River, Huaihe River and lakes. It is a river with a flow of 500 meters, climbing 40 meters above sea level, crossing 500 kilometers of rugged terrain, reaching the thirst of Huaibei and swallowing the rivers in Huaihe River into the river. Since then, there have been no droughts and floods in Huaibei. Where the spring rings, Long Mu adds color and the granary stands upright; When the waves are blue, the streets take off and everything is new. That's what Jiangdu Water Control Project did, and the benefits are beyond words.

You are old, and the planning of the third line of South-to-North Water Transfer Project is ready. The eastern route of Jianghuai expanded first, and Jiangdu showed its glory first. During the meeting, the river surged, crossing Huanghuai and Taidai, helping Haihe River to reach Beijing and Tianjin, Zerun Qilu and Biyan Youyan. Its contribution to helping people can be as brilliant as the sun and the moon.
