both banks are overburden landform, which relatively small topographic gradient and dense vegetation cover, being in a naturally stable state. The left dam abutment is overburden landform the type of which is blocky detritus clay, part of the structures is slightly dense-moderately dense, and the slope is in a naturally stable state. The right dam abutment is also overburden landform, the type of which is block detritus clay, part of the structures is slightly dense-moderately dense and the slope is in a naturally stable state.
