Linear and polynomial results are shown. <br />These are based upon seven target area sites and eleven control sites in two control <br />areas (see Figure 6), for an historic base period of fourteen seasons within a nineteen <br />year period. The plotted data pairs and curve fits for the snowpack analyses are shown <br />in Figures 7a and 7b. <br /> <br />TABLE 5. <br />Precipitation Analysis Results <br /> <br />11 control sites <br />7 target sites <br />Water years: 1983-84, 1986-92, 1997-2001 (14 seasons) <br />Linear: y= 0.9477x + 1.6884 R= .944, R' = .891, se = 0.717 <br />Polynomial: y= 0.0181x' -0.65801 + 8.7035x -27.9540 R=0.958, R'= 0.918 <br /> <br />Control: <br /> <br />Site Name <br /> <br />Elev <br /> <br />Lat Lon <br /> <br />Arches Natl Park, UT 4130 38.37' 109.37' <br />Burro Mln Tel 9400 39.53' 107.36' <br />Columbine Tel 9160 40.24' 106.36' <br />Deadman Hill Tel 10220 40.48' 105.46' <br />Dry Lake Tel 8400 40.32' 106.47' <br />Elk River Tel 8700 40.51' 106.58' <br />Grand Junction WSO 4840 39.06' 108.33' <br />Hamillon 6230 40.22' 107.37' <br />Hayden 8440 40.29' 107.15' <br />Lasal Upr Tel.
