马蹄坑水库距磐安县城10km,控制流域隶属钱塘江水系南江支流。坝址控制集水面积8.5km2。流域发源于磐安县大盘山脉棋架山峰(海拔1073m),主流长度3.5km。流域内植被良好,多年平均年降水量1600mm,多年平均年径流总量850万m3。该水库是一座以城镇供水为主,结合灌溉、防洪、发电、养殖的综合利用工程。该工程拦河坝按50年一遇防洪标准设计、300年一遇防洪标准校核。最大坝高45m,坝顶弧长131m,总库容393万m3,正常库容350万m3,属多年调节小(1)型水库。该工程主要由拦河坝(包括坝顶自由溢流溢洪道)、发电引水隧洞系统、发电系统、管理生活用房等几部分组成。
Mudukeng Reservoir Pan’an County from the town 10km, the control basin under the Qiantang River Nanjiang tributaries. Dam site control catchment area 8.5km2. Basin originated in Pan’an County, large mountain range chess racks (elevation 1073m), the mainstream length of 3.5km. The vegetation in the basin is good, with annual average annual precipitation of 1600mm and annual average annual runoff amounting to 8.5 million m3. The reservoir is a town-based water supply, combined with irrigation, flood control, power generation, breeding comprehensive utilization project. The dam project by 50 flood control standards once the design, flood control in 300 once the standard check. The maximum dam height is 45m, the crest arc length is 131m, the total storage capacity is 3.93 million m3, and the normal storage capacity is 3.5 million m3. It belongs to a small (1) type reservoir for many years. The project is mainly composed of barrage (including crest free spillway overflow), generating diversion tunnel system, power generation system, management of residential buildings and other components.
