<br />CLOUD SEEDING, DATA COLLECTION AND ANALYSIS <br />ASSOCIATED WITH THE COLORADO RIVER AUGMENTATION <br />DEMONSTRATION PROGRAM <br />Report Number WM-87-5 <br /> <br />1.0 INTRODUCTION <br /> <br />For approximately the past 20 years, the Bureau of Reclamation <br />(The Bureau) has conducted weather modification research under <br />the name of Project Skywater. This project has the overall <br />goal of developing an effective weather modification technology <br />for precipitation management to serve a portion of the Nation's <br />water needs. The Colorado River Augmentation Demonstration <br />Program (CRADP) field program is being conducted through the <br />Bureau's Division of Atmospheric Resources Research (DARR) <br />headquartered in Denver, Colorado. <br /> <br />The major objectives of the CRADP are to investigate <br />and improve cloud seeding technology in the Colorado River <br />Basin, to improve the technology's cost-benefit ratio, and <br />to refine suspension criteria. <br /> <br />The Bureau established the Montrose Skywater Office in <br />August 1983, to support field investigations of winter orographic <br />clouds and their modification on the Grand Mesa of western <br />Colorado. A limited exploratory data collection program was <br />conducted on the Grand Mesa from mid-January to mid-February <br />1983. This was followed by more extensive data collection <br />field programs carried out from November 1983 through March <br />1984 and November 1984 through March 1985. <br /> <br />1-1 <br /> <br />I <br />f, <br />I <br />I <br />, <br />,I <br />t <br />, <br />I <br />, <br />I <br />I <br />I' <br />, <br />I, <br />I <br />J <br />i, <br />I <br />
