2003年7月9日,《中国青年报》报道了一则题为“世界文化遗产都江堰再建新坝箭在弦上”的消息,引起了强烈的社会关注。某单位拟在距世界遗产都江堰核心区鱼嘴1310米处修建宽1200米、高43米的杨柳湖大坝。这一工程的上马将改变岷江流向,改变都江堰无坝引水、自流灌溉的性质和特征,使都江堰三大主体工程的综合功能完全丧失, On July 9, 2003, the “China Youth Daily” reported a news item titled “World Heritage Dujiangyan Rebuilding New Dart Arrow”, arousing strong social concern. A unit planned to build a willow lake dam of 1,200 meters in width and 43 meters in height at a distance of 1,310 meters from the mouth of the world heritage site in Dujiangyan. The launching of this project will change the flow of the Minjiang River and change the nature and features of no-water diversion and gravity irrigation of Dujiangyan dam so that the comprehensive functions of the three major civil works in Dujiangyan will be completely lost.
