Las Vegas,Nevada REVIEW - JOURNAL July 21, 1948 Las Vegas Valley Water Withdrawal Keeps Even WASHINGTON, July 21 (AP) ? Residents of the Las Vegas valley of Nevada are withdrawing artesian ground water just about as fast as the underground resources are being replenished. The geological survey said yesterday that annual discharge from wells and springs in the valley increased from 20.500 acre-feet jn 1912 to 31,700 in 1946. It estimates the annual re- charge of underground reservoirs in the valley at from 30,000 to 35,000 acre-feet. Additional water may safely be drawn from wells and springs in Pahrump valley west of Las Vegas and Indian Springs val- ley to the northwest, the survey said. Annual discharge from wells and springs in Pahrump valley has increased from 9,600 acre- feet in 1916 to 17,500 acre-feet in 1946 but the annual rate of re- charge is 23,000 acre-feet. In Indian Spring valley annual withdrawals have declined from a war-time peak of 1,450 acre- feet a year to 800 acre-feet in 1946, while the annual recharge is 4,700 acre-feet.
