Earth dams always must be provided with a spillway or channel of sufficient size to carry off all excess water. The spillway is placed near the top or crest of the dam, in the center or at either side. The spillway should be lined tightly with boards or concrete so that at no point does the running water come in contact with the earth of the dam as the water flows from the upstream side of the dam, through the spillway and down to the extreme downstream side of the dam. Earth will hold still water satisfactorily, but moving water will wear it away. The picture on page 70 shows an earth dam and spillway.
