Since 1910, and particularly since the closing years of World War II, considerable development of the ground water occurring in the valley fill has been made for irrigation purposes. This increase in development has resulted in a progressive decline of the water levels in this area. The results of this study indicate that the water occurring in the valley fill is the only water of good chemical quality occurring in the Portales Valley that can be obtained in quantities that are sufficient for normal irrigation, municipal, industrial, stock, and domestic uses, and that if the present rate of ground water withdrawal is continued, under the conditions presently existent in the valley, this source will ultimately be depleted.
