Taoyuan County, Hunan Province, Baishan Reservoir, last winter, an exception to the method of laying plastic film cover earth dam leakage, received good results. Baishan Reservoir is a small reservoir with a capacity of 227,000 cubic meters and a height of 22 meters. The dam is 85 meters long and is a homogeneous earth dam. Before the treatment, the dam’s outer slope is more than 5 meters away from the dam foundation with an area of 240 square meters. The total ginseng leakage amounts to 10.1 liters per second, which can neither guarantee flood safety nor normal water storage. In the case of unable to carry out grouting, scratching or construction of clay sloping walls and other measures to deal with the winter they take plastic film impermeable treatment, the spring water test, has controlled the seepage
