Coastal reservoir (CR) applied to islands has its special issues to be solved. In this paper, the issues of CRs applied to islands are analyzed by a sample applying to Zhoushan Islands, which is the Chinese first islands city. Firstly, basic status of Zhoushan Islands is presented. Following CR characteristics is introduced. After that, principles of CRs applied to the islands are briefly summarized. Then new conceptions of CR are introduced, one of which is covered by solar panel to reduce evaporation and save energy. For new CRs, collection of fresh water, dam forms, economics comparing with diversion fresh water from mainland and sea water desalination, effect on environment and coordinating with function division of ocean are analyzed. Finally, conclusions will be drawn that application of CRs is one of economical, safety, high efficiency approaches to solve fresh water shortage for Zhoushan Islands.
