The milldam address locates big bridge downstream in the rock valley about the 700 meters. the places decoration has already led a water to generate electricity the hole to take the water, has been gone to adjust to press well, then connected the pressure steel pipe that grows about the 300 meters to go to the power plant site to acquire about the 46 meters water head about the pressure hole with 2.6 kilo meters.There is a interprovincial highway stand the left of the milldan ,the traffic is so conveniency.The Panda river is on the right bank of Minjiang river, it is 87.9 kilo meters long, the drainage area is 1742 .The milldan address is 30 km long from the bayou, control 1467 drainage area,is of the 84％ of the drainage area.The nature egis’s water resource is wealth, Now the river of the Panda has marked out 326.8MW ,aboat having 37.5% of its theories reserves. The Yutan hydrodynamic station stand a line will with once 110 kilo-Volts send a present in return to go into a Sichuan main net.It is not only can accelerate the economy of the natu
