1 INTRODUCTION The proposed Outlying Dian Reservoir is located in the northwest of Xinyang City and 12km away from the urban area. It is a large reservoir. It is a large-scale controlled flood control backbone project on the mainstream of the Huaihe River. The area of the reservoir control basin is 2900km 2 and the designed storage capacity is 3.49 billion m 3. In order to meet the requirements of reservoir construction, the reservoir area control network was established as the foundation work for the initial establishment and construction phase. 2 plan layout network design Shandian Reservoir shallow mountain area, the relative elevation of 150m, Huaihe River south bank of traffic is convenient, North shore traffic is difficult. More trees in the reservoir area. In the 730km ~ 2 reservoir area along the
