某水利水电枢纽距市区约33km，是一座以防洪、发电为主的水利水电枢纽。水库正常蓄水位560m，总库容3亿立方米，具有年调节性能；电站装机总容量180MW，多年平均发电量5亿千瓦时；枢纽工程采用混凝土面板堆石坝，坝顶高程620m，最大坝高140m。
库区需要有大量的移民进行安置，农业人口就业亟待解决；据调查，施工占用的植被类型主要是农田和灌草地，在工程施工区内均未发现国家重点保护野生植物，施工期对国家重点保护植物无影响。本工程施工期基本无生产废水、生活污水排放，清江水体不受污染，两栖类动物生境不会破坏，对两栖类动物影响不大；施工放炮和人员活动会对其他动物将造成一定影响，必须加强对施工人员的宣传教育和管理，将影响降低到最小；工程施工区域内无国家重点保护野生动物分布，总体来讲，工程施工建设对动物影响较小。
