We started obtaining logs on 25 .different observatory w ells, and since 1939, we have a continuous Record of the h y p osta tic pressure on these w e lls.

Mr. Harry Jameson, who is here today, has been carrying out the work in the fie ld fo r us, and through his work and the cooperation he has received, many leaks in the w ells have been stopped; others repaired, and we have tried to carry on an educational program fo r the conservation of water. Through the results of this work, I believe we ba3J SaJred 2 b° 3 m illion gallons of water d a ily, but that work is fa r from being done. We must have a continuous program of conservation u n til a ll o f the wells are fixed and there’ s no waste of water. Mr. Smith has mentioned that we have entered into a cooperative agree- TneP , f ° r .? ? dergr0und Wat6r study with the USG5» That work w&and i t w ill probably take a year or two before we know the whso les tasrtoterdy . inW Je uhlayv, e in stalled several recording setups on the w ells throughout the Valley fo r the purpose of getting daily and hourly data of the hydrostatic pressure, and we are now starting a study of the recharged area. We are fortunate in having cooperation from the U. S. Army Engineers Office and fra$ the o ffic ia ls of McCarran Field, and as a resu lt, we hope that in the next two or three weeks, we w ill have aerial pictures of a ll of the area — 40 miles wide and 60 miles long, and from that as a ba sis, the geologioal survey w ill be computed, esp ecially of the re-charged areas. We w ill start tests to determine the amount of re-charge. It was mentioned, I think by Mr. Strong, about precipitation records in Kyle Canyon, We are sure that within the next month or two, the Weather Bureau w ill have 5 additional precipitation recordings of Charleston Mountains, One at Lee Canyon, one at Cold Creek, one at Robert’ s Ranch, at the southern end, another at a higher elevation in Kyle Canyon, and one on the Western side of the range in Fahrump V alley. Since 1941, with the cooperation of the Forest Service, a survey has been conducted each year in Kyle and Lee Canyons. We are starting to make analysis of the waters from a ll of the w ells of the differen t aquacades, and are making up e water pressure map. Probability tests w ill be conducted, and this w ill a ll lead, we hope in the next year or a year and a h a lf, to a fa ir and accurate picture. We w ill have a fa ir knowledge of the amount of water going into the underground aquacades, and knowing the amount that’ s taken out, then we w ill b© able bo d©b©rmin© jusb how fa r wo can go bowards now dovelopmonb of waber; and you perhaps know bhere are many aquacades* Some of bhemare connecbed. out.

Now, when you d r ill a w ell into an aquacade, you set up what you ca ll an area of influence. That’ s like an inverted pyramid. I f you have a w ell here - and there are some here at the El Rancho Vegas, and you d r il l another w ell three or four fe e t away, and h it into the same aquacade, i t w ill lower the head of the w ell here; therefore, there w ill be a continued lowering o f the hydrostatic pressure of the aquacade by the additional w ell in the area of influence.
