Foot below normal (.. gasp!)

The swamp jumped out of deep drought in early June.

Now at that same level for the past two months it's been stuck.

The graph above shows water depth in Big Cypress National Preserve (the blue line) from late 2013 to present.  Water depths are graphed relative to major vegetative communities (dark blue for mesic pines, light blue for hydric pines, green for tall cypress, orange for the middle of cypress domes, red for dry season refugia and dark red for severe drought).  The lighter shaded band shows the historic range as calculated from 1993 to present.  The darker band within the lighter band shows the normal range with the white dotted line within that showing the long-term median water table level.  


How stuck?

The Preserve's water table is a foot below normal for this time of year.


Even worse than that it's off the chart!

(i.e. At a new record low for July.)
