Working Draft Florida River Flow Patterns and the Atlantic Multidecadal Oscillation Appendix A Page 1 of 152 List of Appendix Figures
This appendix contains two types of figures. The first figure for each waterbody is a comparison of two multidecadal time periods (1940-1969 and 1970-1999) with summary statistics. The second figure of each figure pair is a presentation of decadal median daily flow plots.
