Figure 20. Comparison of smoothed average rainfall deviations (f-value = 1/26) and trend adjusted water-level deviations in well HE-517. The fraction of agreement (fa) for the lowest 20th percentile of the data was 0.60. For this comparison, water level was detrended using a linear regression and was not lagged relative to smoothed rainfall. Asterisk represents standard deviation below the long-term monthly averages of water level and rainfall. These values for rainfall have been multiplied by 3 so that the resulting rainfall values can be readily compared to the water-level results. This multiplication does not affect the fa.
