Swamp shrivels to lowest spots

It's hard to believe after so much summer rain ...

To see swamp water retreat to its last refuge, its lowest spots.

This chart displays a history
of surface water flooding levels
in Big Cypress Nat'l Preserve.

The size and color of the data points
indicate the amount of water

The cause?

Lack of rain (see below).

Monthly rain in swamp

Our record "wet" wet season
has been followed by a 5-month
run of relatively rainless months

"Green out" begins

Usually the sight of plants "greening out" ...

Is a sign of recent rains.

Except in the swamp where it means the start of seasonal drought.

Tale of the Cocohatchee

The river is still there ...

You just have to look to find it.

Cocohatchee River

As for the canal:

It's easy to find.

Cocohatchee Canal

It's deeper, wider, longer and straight as an arrow ...

And parallels modern-day Immokalee Road.
