石門水庫為具有灌溉、發電、給水、防洪及觀光等多目標水利設施，對桃園地區農業生產、工業發展、人民生活水準提升及水旱災害防治等方面均有重大貢獻。依據103年調查成果，自民國53年6月14日竣工起營運迄今，歷經極端颱洪事件後，水庫總容量已從原設計3.09億立方公尺減少為2.01億立方公尺，使得穩定供水及防洪操作之風險提高。 北水局於民國99年辦理「石門水庫阿姆坪防洪防淤工程可行性規劃」工作，完成地質鑽探12孔，總深度1,000公尺，並進行隧道沿線4,200公尺地電阻影像剖面探測，考量有部份地質疑慮尚待釐清，北水局爰辦理「石門水庫防淤隧道工程(第1階段)補充地質及地下水調查」，以為後續基本設計之依據。

Shimen Reservoir has the functions of irrigation, power generation, water supply, flood control and tourism. Through years of operation the reservoir has experienced severe siltation. The water capacity decreases from 3.09×108m3 to 2.01×108m3. The frequency of heavy rain has increased by extreme hydrological events of climate change. Therefore, it has become imperative to develop measures to enhance desilting and flood-discharge capabilities of the reservoir. Northern Region Water Resources Office executed “Feasibility Study of Amuping Desilting Tunnel Project for Shimen Reservoir”in 2010. The project finished 12 boreholes (total length was 1,000m) and 4,200m of Resistivity Image Profile on the surface of the whole tunnel route. To consider some geological problems, Northern Region Water Resources Office executed “Supplementary Groundwater Level Measurement for Desilting Tunnel of Shimen Reservoir (First Stage)”for the basis of the follow-up basic design.
