Graph showing trend adjusted water-level deviations in well C-392 Graph showing comparison of smoothed average rainfall deviations (f-value = 1/26) and trend adjusted water-level deviations in well C-392

Figure 13. Comparison of smoothed average rainfall deviations (f-value = 1/26) and trend adjusted water-level deviations in well C-392. The fraction of agreement (fa) for the lowest 20th percentile of the data was 0.57. For this comparison, water level was trend adjusted using a linear regression and lagged relative to smoothed rainfall deviations by 2 months. 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.

Funding for the USGS to design and maintain this site has been provided through a cooperative agreement with the South Florida Water Management District (SFWMD). Water-level conditions are monitored by the USGS with support from Federal, State, and local cooperators.
