<br />Conclusion <br /> <br />The first increased runofT/cost analysis was performed after the 1999-2000 winter <br />cloud seeding season by the Division of Water Resources. Since then. the state of Utah <br />has experienced a signilicant drought. These drought years have affected the data record <br />and have been a factor in the difference in estimated runoff and cost that was determined <br />in the 2005 analysis. As more years of data arc collected a better average can be <br />determined. A summary of the 2000 vs 2005 results is shown in Table 6. The total cost <br />per acre~foot increased from S 1.02 in 2000 10 $1.69 in 2005. <br />Overall the runolTresults may be a conservative estimate. By using ApriI1~' <br />snow water content we are underestimating the results compared to using December <br />through March precipitation amounts. <br /> <br /> Table 6. <br />Comoarison of 2000 \"S 2005 Cloud Seedinp Proiect Area Results <br /> Increase in Increase in Increased Increased <br />Project Areas April I Aprilt Runoff Runoff <br />SWC SWC (ae-fl) (ae.fI) <br /> 2000 2005 2000 2005 <br />Cache County ]8.0 10.0 94.600 50,000 <br />West Box E]der 18.0 18.0 12..'00 ]3,600 <br />Tooele Coumy 20.0 18.0 9,800 9,-tOO <br />Sevier River 7,0 4.0 65,800 30,800 <br />Cedar-Beaver 7,0 4.0 12,200 6,700 <br />West Colorado 7.0 4.0 -10,000 19,600 <br />Virgin Ri....er 7,0 4.0 1-1,800 9.000 <br />Western Uinta's NA 2.3 NA 13,200 <br />Iligh Uinta's :'><A 6.0 NA 70,500 <br /> C'osIJac-rl CosUae.ft <br />Total 249.600 $1.02 222,800 $1.69 <br />Northern Utah Project ] 06,900 $0.82 63,600 $1.20 <br />Central and Southern Utah <br />Project 142,600 $1.17 75.500 $2.11 <br />Western Uinta Project SA ;>';A 13,200 $-1.96 <br />High UlOla Project ;>';A ;>';A 70,500 $1.08 <br /> <br />10 <br />
