Where's the water table now?

The water table is dropping,

But still fairly slow.

The solid blue line on the hydrograph above shows the water level in Big Cypress National Preserve from 2013 to present. The dotted white line shows the long term average water level as calculated from 1993 to present. The water table has been dropping fairly steadily for the past three months to the point that -- now -- water has receded to the inside fringe of the cypress domes.

Cooler weather means evapotranspiration is low.

That helps keep the water table up this time of year even without rain.


It isn't until after March that -- rainfree -- the water table starts to nosedive fast.
