From Round-the-Island North Road you can see Ledaoao Reservoir in the distance. It is located in the northern part of Xiju Island , in an open valley that reaches northeastward and then turns north. The island was short of water and the wells drilled by the people were insufficient to fill their needs, so the military built the dam here to form the reservoir and serve the needs of daily life, military defense, and irrigation. When the weather is clear, the Round-the-Island North Road interpretive plaque is a good location for viewing mainland China and watching the sunset.
