"target-coDtrol" technique. <br />Central Colorado Rockies furni.h the be.t control area for <br />evaluation in the regioD aa veIl .. an area where the moet <br />locial and environmental problema are expected. <br /> <br />The <br />.t.thtie.l <br />complex <br /> <br />At the end of 10 yeara' operation a thorough evaluation of augmentation <br />~OUDt. and environmental effect. viiI be made and decision. to continue <br />the program and to aeed the Central Colorado Rockiea can be made. <br /> <br />The Inltial five area. have an average annual potential of 1.339,000 <br />acre-feet, but allowing for seeding Iu.penaions which reduce yields, <br />about 1.200.000 acre-feet are expected. The 14-year total augmentation <br />i. about 12,000.000 acre-feet at . COlt of $36.6 million or about $3 <br />per acre- foot. <br /> <br />Steps <br /> <br />ry 1976 and Transitional Quarter - Begin preliminary environmental <br />and legal-social studies and initiate planning discussions for <br />Federal-State cooperation. <br /> <br />FY 1977 - Continue preliminary studies and planning, start field <br />survey and design studies. <br /> <br />FY 1978 - Complete desig~ and finalize coordination agreements, <br />continue preliminary studies. <br /> <br />FY 1979 - Procure and inatall instrument in control areas and seeding <br />generator systems in the Uinta mountain area and begin indepth environ- <br />mental and economic studies (begin planning studies for Wind River <br />mountain area project). (See Tsble 1 for tentative initiation schedule.) <br /> <br />FY 1980 - Begin first of 10 years' seeding research in Uinta area <br />on October 15. 1979 (system inetallation in Wind River and planning <br />studiu for Park IUtnge areu). (See Table 1.) <br /> <br />FY 1981 to 1989 - Continue Uinta seeding demonstration (begin first <br />of 10 years' seeding in Wind River Area on October IS. 1980). <br /> <br />FY 1990 - Analyaia and reports on Uinta Project (continue other <br />projects). <br /> <br />FY 1993 <br /> <br />Complete 10 years of seeding in San Juan mountain area. <br /> <br />FY 1994 - Analyses and reports on San Juan Project and overall Colorado <br />River Augmentation Demonetration Program evaluation. <br /> <br />Key Protect Features - Over 200 remote-controlled ground baaed gener- <br />ators that burn about 30 grams of silver iodide per hour will accomplish <br />the major psrt of the seeding. These are located at lower elevations <br /> <br />10 <br /> <br />
