The Liquid Heart of the Everglades

The state of Florida is working on a plan to restore water flow to its troubled Everglades. It wants to
buy a huge sugar grower and the land it owns between Lake Okeechobee and the Everglades. Ann
Dornfeld went out on the lake to find out what's at stake:

The first thing to know about Lake Okeechobee is that it's not your stereotypical clear blue lake. It's
shallow, murky, covered with tall grasses, and thick with everything from birds and rabbits to frogs
and alligators.
The lake is about 35 miles wide. It's known as the 'liquid heart' of the Everglades. And Paul Gray is
here to take its pulse.
Paul Gray: "I think it's a glossy!"
Ann Dornfeld: "What's that?"
Paul Gray: "A glossy ibis."
Gray gets excited about birds. That makes sense – he's the Science Coordinator for the Audubon
Society's Lake Okeechobee Watershed Program.
It's his first time out on the lake since the last big storm, and he's eager to see how it's doing.
Stormwater is diverted into the lake from development and farmland like the U.S. Sugar fields. That
floods the lake, which has nowhere to drain because it's surrounded by a dike.
The best way to get to the middle of a marshy lake is an airboat.

As the boat zips across the grassy lake on a cushion of air, brightly-colored bugs and tiny green frogs
the size of your thumbnail land inside.
Once we skid to a halt, Paul Gray scans the water, and throws up his hands, disappointed.
"We've stopped in an area that's probably four feet deep now. This is very, very sparse – just a little
stem sticking up every four to five feet. If everything was working right this would be all vegetated,
full of birds and stuff. Right now I'm not sure what will happen to it. [sighs] It's a little demoralizing
right here, but we'll look for some better spots."
All this vegetation drowned in the last big storm.
"All of Okeechobee's water used to flow into the Everglades, but now it doesn't do that anymore."
Instead, extra water is dumped into the fragile estuaries. They're supposed to be a delicate mix of
saltwater and freshwater. And dumping all that lake water into them destroys the ecosystem.
"And the great tragedy is in 2004-2005 we had so many storms, and we dumped so much water
from Lake Okeechobee that we could've met all our water needs for a decade. The year after dumping
all that water out, we were in a severe drought and the farmers were only getting 45% of the water
they wanted."
Last summer, the state of Florida announced a tentative deal with U.S. Sugar Corporation to buy the
company out. U.S. Sugar's land blocks the flowaway between the lake and the Everglades. The state
proposes returning some of the land to its natural marshy state, and using other parts for stormwater
reservoirs. Gray says the U.S. Sugar deal would be a huge boon to the lake and the Everglades. It
could even improve the birdlife in northern states and Canada that fly south for winter.
"When those little warblers and things reach Florida, they've gotta get fat. They need to double their
body weight before they fly across the Gulf of Mexico, or they can't make it!"
We arrive at a shallower part of the lake, and Gray pumps his fist in victory.
"This is much better news. We're sitting in a big patch of green plants with little white and pink
flowers. It goes on for several hundred yards. This is called smart weed. It produces little very hard
black seeds. And ducks love these seeds, and migratory seed-eating birds like sparrows and other
things love these seeds. When all of the wintering waterfowl get down here they're gonna have a ball
with this! [laughs] Wow. That's nice. Alright, we can go."
It's a small success. But Gray says until the flow of water into Lake Okeechobee is returned to normal,
the liquid heart of the Everglades will be struggling to beat.
