Yimeng mountain area is water deficient area in Shandong province. Due to its complicated geological conditions, water exploration is very difficult in this area. Through analyzing meteorology and hydrology, lithological characteristics, geological structure and landform, structures and water abundance of aquifer in different sections have been primarily identified. Combining with comprehensive exploration methods, such as hydrogeological survey, geophysical prospecting and drilling, eight exploration and extraction holes have been successfully drilled which could meet not only the drinking need of 30000 residents, but also meet the irrigation demand of 300 mu land. Great economic and social benefit have been achieved. It will provide successful experiences for instructing further exploration of water in waterdeficient area.
