We found reasonably good correlations in some <br /> <br />areas of the target; however, the reliability of these correlations is sufficiently <br /> <br />lacking that the relationships found do not explain 100% of the possible variations <br /> <br />in the date, therefore, the quantity of water achieved from cloud seeding is referred <br /> <br />to as an estimate and not a "for sure" amount. <br /> <br />Stream Station <br /> <br />% Inca <br />Precip. <br /> <br />% Inc <br />StreamFlow.- <br /> <br />1.
