Show Climate Not Affected By Boulder Dam Reservoir summed up his evidence with this observation: "By comparison, the water in a pitcher at a speaker's stand is about as effective in aid-conditioning an auditorum as Lake Mead is in modifying the climate." Seventeen pilots and co-pilots of the Western Air Express, which sends planes daily over Boulder Dam and Lake Mead, were questioned. ques-tioned. Fifteen said they had noticed no-ticed no change in atmospheric conditions. Two said they believed the time elapsed since Lake Mead began to fill in February, 1935, was too short to make any change evident. No Change Noted by Residents Residents near Boulder Dam and in Boulder City, Las Vegas and Kingman, Ariz., reported they have not noticed any climatic differences. dif-ferences. George V. Sager, associate meteorologist mete-orologist at Reno, saidd. "The creation of Lake Mead has had no appreciable effect on the climate of southern Nevada." Uy JOHN CA1ILAX l!nit'(l i'rewi Staff Correspondent BOULDER CITY, Nev., Jan. 4 LM!i Lake Head, world's largest man-made water body, has not exerted any influence on the climate cli-mate of America's driest desert, where it stretches for 100 miles behind Boulder Dam. And it never will say government experts. "Lake Mead was not expected lo influence the weather of the southwest," declared John C. Page, acting reclamation commissioner. "It has not done so and it will not." Investigation was started last summer when unauthorized statements state-ments circulated that perceptible changes in the weather and climate cli-mate were noticeable as Lake Mead grew behind the dam barrier bar-rier across the Colorado river. The reclamation bureau calculated calcu-lated in advance the rate of evaporation evap-oration from Lake Mead which could be expected when the lake formed In the desert. These calculations cal-culations indicated insufficient moisture would be taken into the air to alter weather conditions not iccably. ttviipurution Cheeked Daily Tests are underway at the lake to check precisely the actual evaporation daily and records so Jar indicate the advance calculations calcula-tions are correct. Meantime the government has collected information from nearby residents, airplane pilots who fly over Lake Mead daily, and from meteorologists of the U. S. weather weath-er bureau at Phoenix, Ariz., Reno, and Salt Lake City, the vast area rHUrrounding Lake Mead. J. C.
