Brief reprieve

It's amazing how fast ...

Resurrection fern (foreground) responds to rain.

A wet swamp is a better swamp

As for filling up the dome (background),

That will take a regular onslaught of similar storms.

And longer and more than usual because the water table is so low.

Water cycle steps in

From one day to the next ...

The dome below (sort of) filled up.

But who's complaining?
Talk about a perfect rain!

But with the water table so low,

Don't expect it to last.

It'll take more than one storm to lift this swamp out of drought.


As suspected, dry

Just to double check

How deep is the drought?

Judging from this marl chip, seasonally dry at least.

A better metric would be to walk into the dome.

Ideally in April it's peat would still be dry.

But why waste the time when I can see the answer right at my feet.

Drought exposed limestone
of the Tamiami Canal

Judging from the canal, the water table has dropped ...

To the point that most of the domes have gone dry.

I walked to the dome anyhow.

Looks can be deceiving

Looks lush down there ...

But don't mistake that with moist.

The dome is dry

The spring green out coincides with seasonal drought in the swamp.

Bravest tree of them all

Fire stopped short ...

Of running into the middle of this dome.

Center of dome to left

The cypress didn't stop it.

The pond apple did thanks to its still soggy peat.

That's one brave tree.

Drydown marches on!

Despite a dash of rain,

The seasonal decline of the water table marches on.

This chart shows where the Cowbell Fire ranks
seasonally and in terms of water depth
relative to past major wildfires

In fact, since the start of the Cowbell Fire ...

The preserve-wide water table has dropped about a half foot.

The good news about that rain was it fell right on the fire, not enough to put it completely out, but it did raise the water table about 4 inches.  Don't expect it to last.

A deep drydown season is still upon us.

And compared to past deep drydowns this one is still quite young.
