The news for Lake Okeechobee, the
Everglades’ lungs and kidneys, is mixed at best. But at last we understand
what’s at stake and how to heal the lake.

July 10, 2011, 9:00 a.m., and the heat makes me wonder how
people can live in South Florida in high summer. Paul Gray and I push our
earmuff bands forward to hold down our hats and feel the welcome rush of
cooling air as Don Fox guns his airboat out onto the heart, lungs, and kidneys
of the Everglades—Lake Okeechobee.
To our south, hidden by 467,200 acres of dry lake bottom and
shallow water draped over the curve of the earth, lie Florida’s ever-thirsty
sugarcane plantations, Big Cypress National Preserve, Everglades National Park,
and Florida Bay. To our north the lake collects the now-feeble flow of its
major artery, the damaged but recovering Kissimmee River. All this is part of
the “greater Everglades.” Earth has no other place like this 4.5-million-acre
grassland-and-savanna landscape, with its rich mix of salt, brackish, and
freshwater habitats. The greater Everglades sustains
species or subspecies of at least 1,030 plants, 60 reptiles, 75 mammals, 430
fish, 345 birds, and 40 amphibians.

This is the second time Gray, Audubon of Florida’s
Okeechobee science coordinator, and Fox, a fisheries biologist with the Florida
Fish and Wildlife Conservation Commission, have guided me around the lake and
its marsh system by airboat. A decade earlier Audubon had sent me here to
report on Okeechobee’s human-caused illnesses (see “Big Water Blues,”
July-August 2001). The word Okeechobee is Seminole for “plenty big water.” Now
there isn’t plenty or even enough. But low water was exactly what the
long-dormant seedbed in the bottom muck needed to germinate.
The lake and marsh systems have undergone astonishing
recovery since I last saw them. This has not been the result of enlightened
management—just the opposite. The U.S. Army Corps of Engineers manages the
lake’s inflows and outflows, and when it comes to controlling natural systems,
the Corps is rarely in doubt but frequently in error.
There had been a drought in 2001, too. And in the two years
that followed there had been gradual recovery. But high water from the
hurricanes of 2004 and 2005 erased that recovery. Until 2006 the Corps had,
when possible, kept the lake so high that its submergent
and emergent vegetation drowned and no sunlight reached the seedbed. The
strategy was to make sure the sugar industry and Gold Coast lawns would always
have lots of water. But in spring 2006 the Corps’ ancient, earthen Hoover Dike,
which rings the lake, began to fail under the pressure of Hurricane Wilma’s
water. So the Corps dumped billions of gallons. Then came
the drought of 2007. With little water retained in the Kissimmee River
floodplain (because the Corps had hacked and gouged it with drainage canals),
the lake went down to 8.82 feet—a foot lower than in its recorded history.
Midges and shad are two of the lake’s most important
food-chain foundations, passing their energy to small fish, to fish that eat
the small fish, to turtles, alligators, and birds that eat fish of all sizes.
After all the high water from the hurricanes, midge larvae went from about
10,000 per square meter to two (not 2,000—two). With dirty water again blocking
sunlight, plankton disappeared and with it the planktivorous
shad.
But for now at least, the midges and shad are back. Mudflats
we had slogged across in 2001 clutch chartreuse carpets of wild millet, an
important waterfowl staple. Young bulrushes stabilize what had been eroding
edges of the marsh piled with windrows of rotting plants ripped out by waves.
Across thousands of acres where we’d seen only black water, yellow blooms of
American lotus wave in the hot wind. Marsh plants proliferate where we’d
encountered an anaerobic witch’s brew of moldering vegetation. Alligators,
turtles, and fish swirl from our path.
Everywhere we go we are surrounded by birds orbiting above
us, lifting from the surface, dropping onto it, bobbing, dabbling, probing, and
strutting through reborn marshes and newly oxygenated
water. We count 47 bird species, including long-absent roseate spoonbills,
mottled ducks, blue-winged teal, black-necked stilts, long-billed dowitchers, lesser yellowlegs, black skimmers, little and
great blue herons, black-crowned night-herons, tricolored herons, great and
snowy egrets, least bitterns, white pelicans, glossy and white ibises,
limpkins, wood storks, and Everglade snail kites, crow-sized raptors with
sharply hooked beaks. On Eagle Bay Island, lifeless in 2001, there had been 4,518
wading-bird nests in April.
Okeechobee’s recovery has made a strong impression on
Nathaniel Reed, the lake’s and the Everglades’
tireless, ageless advocate, who served presidents Nixon and Ford as Assistant
Secretary of the Interior and Audubon as a board member. Reed takes people on
airboat rides to raise money for the Everglades Foundation. “They don’t
understand why Paul Gray, Don Fox, and I get weepy at certain places,” he says.
“This was all open, muddy water, and here we are going through magnificent
stands of native plants. It’s hard to explain how much this means to us. It has
been the most unbelievable example of nature’s forgiveness I have ever laid
eyes on.”
But too little water for too long can be
as hurtful as too much. In the drought of 2011 the South Florida Water
Management District snatched defeat from the jaws of victory by dropping the
lake to a near-record low in order to give sugarcane growers all the water they
wanted—more, in fact, than they get in wet years. While the Corps has ultimate
authority over Okeechobee water management, the district handles allocations,
invariably doing what it wishes.
Even as the marsh plants were rebounding, other parts of the
ecosystem were flickering out. Apple snails, recovering from the high hurricane
water, were dying again. As soon as a marsh goes dry they estivate in the mud,
becoming unavailable to creatures that eat them. Then, if the water doesn’t
return within three months, they die.
No creature depends more on apple snails than the Everglade
snail kite, one of the planet’s most endangered birds. Everglade snail kites
don’t occur outside southern Florida, Cuba, and northwestern Honduras. And the
Florida supply of this subspecies (there are two others, in Central and South
America) is thought to be fewer than 900—down from 3,500 in 1999. In the years
I’d been away, Okeechobee’s snail kites had annually produced an average of
three fledglings. But in the spring of 2011 there had been 44 nests. It looked
like a banner year until the district dewatered the lake. Only 14 nests
produced fledglings, and it’s unlikely that any survived.
“We waited so long to get kites back,” says Reed, “and to
lose this group is just so sad. To let birds near fledging starve to death
while we were releasing water is insane—and a violation [under the Endangered
Species Act].”
The disaster seems to have been partly the work of the
state’s new Tea Party governor, Rick Scott. While the state water districts
aren’t under direct control of the governor’s office, Scott didn’t hesitate to
give advice. All spring he and the South Florida Water Management District
ignored Audubon’s repeated warnings to ration water for Everglade snail kites.
The public has made an enormous investment in Everglades restoration. The Water Resources Development Act
of 2000 authorized $1.5 billion for initial work. And up until 2010 the federal
government had spent $765 million and the state $1.5 billion. But Scott, who
likens writing budgets to cleaning attics, has tossed that investment out the
attic window along with many of the professionals the public had hired to fix
the Everglades. One of his first actions was to petition the Environmental
Protection Agency in an effort to relax regulations for limiting the fertilizer
and animal waste that had been choking the greater Everglades for decades.
Here’s how well those existing regulations had been working: In 2000 the EPA
accepted a water-district limit for phosphorus entering Okeechobee at 140
metric tons a year. Today the lake gets about 600 metric tons. On watershed
dairy farms, Gray and I saw one of the reasons—cows were standing and defecating
in ponded tributaries.
On May 26, 2011, Governor Scott signed a bill that slashed
the water district’s budget by $128 million (30 percent), crippling its ability
to do authorized restoration work. Then in June he
flew to the district’s Palm Beach headquarters in his private jet for a
“ceremonial signing” of the bill. “To come to Palm Beach County and rub salt in
the wounds of people who will soon go home to their families unemployed is
insulting,” State Representative Jeff Clemens (D-Lake Worth) told The Palm
Beach Post. “Can you imagine the governor showing up to celebrate your
unemployment?”
Also in June, Scott appointed to the water district’s
governing board Juan Portuondo, former president of
the Montenay Power Corporation, whose trash
incinerator, known as “the Miami Monster,” polluted the Everglades. Later,
according to the Miami-Dade County inspector general, Portuondo
was paid by Montenay to lobby for it and
simultaneously paid by a company hired by the county to inspect its Miami
Monster.
Jeb Bush and Charlie Crist, the two Republicans who served
as governor before Scott, were Everglades champions.
In 2003–04, under Bush, $225 million was appropriated for Everglades
restoration. In 2007-–08, under Crist, $100 million was appropriated. And Crist
conceived and consummated (though it wasn’t fully funded) a $1.75-billion deal
to buy out 187,000 acres of wetlands owned by U.S. Sugar. Scott’s proposed
2011–12 budget for the Everglades calls for $17
million.
“The Everglade snail kite disaster was wholly manmade and
wholly predictable,” declared Gray. “Sometimes when we’re talking about kites people
say, ‘Well, that’s just one bird.’ But kites are a symbol. When kites disappear
it means turtles are disappearing, frogs are disappearing, fish are
disappearing, insects are disappearing, neotropical
birds that depend on the insects are disappearing. ”
As with most of the lake’s ecological ills, the kite loss is
the result of Army Corps engineering. The Corps finished girdling the lake with
its Hoover Dike in 1967. And four years later it finished “improving,” as it
says, the Kissimmee River by slicing out its meanders and converting it to a
lifeless gutter so that its water shot unsettled and unfiltered into the lake.
Then, after the water dropped much of its suspended organic matter, the Corps
vented it to the Atlantic and Gulf of Mexico via the “improved” and similarly gutterized St. Lucie canal and Caloosahatchee River.
Before this replumbing of the
northern Everglades, summer rain had collected in wetlands and aquifers and,
during all but the driest of months, had been doled out to the lake and a
cleansing, 100-mile river of sawgrass and
pickerelweed that metabolized phosphorus, filtered sediments, and delivered
soft, sweet water to Florida Bay. Okeechobee’s natural exhalations were as
beneficial as its inhalations because they never lasted long and they allowed
organic muck to dry, decompose, burn, and blow away. Insect larvae and
succulent vegetation flourished in the shallows, providing food and cover for
turtles, frogs, salamanders, alligators, wading birds, shorebirds, and
waterfowl. Then the insects would shuck their larval skins and take wing in
vast clouds that sustained North America’s energy-drained songbirds as they
funneled through Florida on their way north and south. You can’t have a healthy
system if you flush and fill it like a toilet.
“The water district will tell you it dewatered the lake for
the economy,” says Gray. “Whose economy are we talking about? In winter the
town of Okeechobee’s population doubles to something like 70,000 due almost
entirely to the influx of anglers. But last spring they couldn’t even use the boat ramps [so severely did the district shrink the
lake].” When the lake’s fishery is healthy it annually contributes $203 million
to Florida’s economy.
In late May the district installed pumps to continue
allocations for sugarcane irrigation, thereby further flouting not only the
Endangered Species Act but the state rule that forbids it to let the lake’s
level fall below 11 feet for 80 days more than once in six years. “That’s the
power of the sugar people,” says Reed. “They can still reach someone in
Washington.”
I needed to compare the condition of the whole watershed
with what I’d seen from a Cessna 172 in 2001. Receiving no invitation from
Governor Scott to fly me around in his private jet, I accepted one from his
Palm Beach neighbor Gary Lickle, a board member of
the Everglades Foundation. Lickle picked me up at the
mouth of the Kissimmee River in his 900-pound Cubcrafters
Carbon Cub floatplane, which can take off in less than three seconds and slow
to 28 mph without stalling. There’s room for one passenger—directly behind the
pilot.
Lickle, who runs a trust company,
grew up hunting and fishing, and now, as he says, hunts the sea in summer and
the land in winter. “We all lately learned how important the Everglades are to
our existence,” he remarked. “We want to make sure all this is around for our
kids and grandkids because it’s so special.”
As we flew over the gutter that used to be the Kissimmee
River I noticed a metal stick moving between my knees. “Is that how you fly
this thing?” I inquired.
“Yes,” he said. “Take over.” With some trepidation I steered
north, still following the straightjacket the Corps had forced the Kissimmee
into, thereby destroying its magic along with the magic of its name, which it
changed to “C-38.” When the river had its way, all marshes within and well beyond
its floodplain couldn’t be drained because there was no downhill. With the
advent of C-38, landowners over thousands of square miles cut canals, draining
their wetlands into it. Perishing with the river were millions of fish,
turtles, frogs, salamanders, alligators, snakes, mammals, and marsh-dependent
birds.
My mood darkened as I flew north. But suddenly the natural
river reappeared and with it all its old beauty, including the birds. Having
paid the Corps $35 million to destroy the river, taxpayers have so far paid it
$291 million to fix part of it. When that partial fix is completed they’ll be
out an estimated $980 million. The Corps had placed 16 miles of C-38 back in
the original riverbed and blown up one of the five gated spillways with which it
had vainly attempted to control flows. It will blow up another spillway and
restore an additional six miles, leaving 30 miles of gutter.
One of the ways the district is attempting to heal the
greater Everglades is with stormwater treatment areas
(STAs)—giant filter marshes, frequently connected to reservoirs. Presently we
swung out over the $75 million Lakeside STA, which will annually remove 19 tons
of phosphorus. But STAs are expensive, and in big rain events water goes
through so fast it doesn’t get cleaned. To comply with the Clean Water Act the
district must cut phosphorus input by 460 tons a year. If it depends on just
STAs instead of other options, such as forcing best management practices on
dairy farms, it can’t possibly find the money it needs. As things stand now,
everyone pays save polluters.
So slow and low were we flying when we reached the lake that
I cheerfully relinquished the stick to Lickle. A
half-mile swath of brown, withered cattails marked the area Don Fox had sprayed
with herbicides. Cattails are native, but when water going to Lake Okeechobee
carries more than 20 parts per billion of phosphorus they become invasive. The
lake’s inflow now carries 150 to 200 ppb, and as a result cattails and other
nutrient-swilling plants are destroying natural diversity all the way to
Florida Bay.
We seemed to hover with the ospreys. A manatee that had
negotiated the entire St. Lucie canal sashayed over a shallow bar. Tire-sized
nests tilapia had excavated with their tails gave wet and newly dry sections of
marsh the appearance of having been saturation bombed by B-52s. I could ID most
birds, see every turtle and alligator and many fish. I could even make out the
rouge of pinhead-size apple snail eggs festooning plant stems.
These were the eggs of South American apple snails,
accidentally introduced from private aquaria since my last visit. Adults really
are the size of apples. The natives—the size of golf balls—produce white,
BB-size eggs and far fewer of them. The alien snails seem to tolerate wild
water fluctuations better than the natives; they thrive where alien hydrilla has extirpated the natives; and, best of all, Everglade
snail kites eat them.
Unfortunately, the alien snails have taken major hits when
the state (formerly the Florida Department of Environmental Protection and the
water district and more recently the Fish and Wildlife Conservation Commission)
has herbicided hydrilla
along with other plants, alien and native, so that anglers can motor around
lakes in the Kissimmee basin. For years Gray tried to get spray crews to avoid
the kite nests they consistently destroyed when they poisoned supporting
vegetation. “They told me the kites could just go somewhere else,” he says. “I
kept telling them, ‘Guys, you can’t do this. It’s a direct violation of the
ESA. Your director could go to jail.’ We were getting nowhere with them.”
Then, two years ago, Reed’s wife, Alita,
rousted him from sleep because she’d just gotten word that the Department of
Environmental Protection was poised to poison hydrilla,
water hyacinth, and other plants around active Everglade snail kite nests on
Lake Tohopekaliga, in the Kissimmee’s headwaters.
Reed raced to the scene where the team was going to assemble. By sheer luck he
raised water district board chair Eric Buermann by
cell phone. An appalled Buermann promised that any
spray order that had been given would be canceled in seconds. It was, and,
largely as a result, Lake Tohopekaliga with its alien
hydrilla and alien apple snails is one of the few
places kites are doing well.
But like Hollywood’s cuddly gremlins, seemingly beneficial
aliens have a way of turning nasty. Native apple snails graze primarily on the
algal scum on plant stems. The aliens eat the actual plants. The exotic snails
are heavier and tougher, and one fledgling was seen to spend seven hours trying
to open one.
As Gray and I hiked and kayaked along Hickory Hammock Trail,
near where the Corps had blown up one of C-38’s gated spillways, it became
clear to me that even with Okeechobee’s current ills, its future was brighter
than it had been in 2001. Willows, maidencane,
pickerelweed, marsh mallow, and arrowhead were
surging back in and along the old, newly filled meanders. “The river is better,
and there’s an understanding of the lake’s problems,” Gray declared.
Facilitating that understanding has been an Audubon report
released in 2007 demonstrating that the water district’s goal of 300,000
acre-feet of upstream water retention needed to be at least 1.2 million
acre-feet. The report helped get that goal fixed and was instrumental in the
passage of two bills that set better pollution-control rules and increased
funding for water-retention projects during wet periods. Water is retained
three ways: by reservoirs, pumps that send it into subterranean saline formations, and payment for environmental service whereby
ranchers agree to retain water on their land.
The last of these options—designed by the World Wildlife
Fund with technical guidance from Audubon—is the least expensive, keeps land on
tax rolls, cleanses water, reduces wildlife-killing blue-green algae blooms
that occur on reservoirs, and helps wildlife by creating wetland habitat. There
are eight cooperating ranches within the Florida Ranchlands Environmental
Services Project that can collectively hold 10,682 acre-feet of water.
Originally this was a pilot program funded by grants from the Natural Resources
Conservation Service
and the W.K. Kellogg Foundation. So well did the pilot program work that the
water district has taken over funding and management, and in 2011 it started
soliciting payment for environmental service sales from more ranchers.
Money is just one of the benefits ranchers get when they
agree to retain water. Near Sebring, Jimmy Wohl
showed Gray and me around his family’s Rafter T Ranch. He used to pump out the
diked section so he could grow grass for the cows, but no matter how much he
pumped, the earth stayed wet and the grass did poorly. When diesel fuel hit $2
a gallon he quit pumping. Now he has converted that section to a 150-acre
retention area within the 1,000-acre wetland that the state pays him to keep filled
during rainy periods. He plants it with limpograss,
which can tolerate lots of water and is reasonably nutritious. “Limpograss can still grow when the land is flooded in
summer and when the cows aren’t grazing here,” he said. “And by October, when
most of the water is off, it helps feed them till we sell the calves in late
June.”
“If water management doesn’t improve, the Everglade snail
kite will probably go extinct in 20 to 30 years,” said Eric Draper, executive
director of Audubon of Florida. “But we’ve finally got the water district’s
attention; at least they’re talking about the problems.” Even as he was
depressing me with the worst news about the greater Everglades he reminded me
that there’s good news as well. Although Crist’s sugarcane plantation buyout
got whittled down from $1.75 billion and 187,000 acres to $197 million and
26,800 acres, it has gone through, and the state retains the option to buy the
remaining property. To facilitate desperately needed water flow, the House
Subcommittee on Appropriations has approved a 5.5-mile addition to the one-mile
Tamiami Trail bridge. With
this Congress and this economy that’s a miracle.
Recently the shells of golf-ball-size alien snails have been
showing up under kite nests. That could mean the parents are teaching their
young to select for immature snails they can open. Maybe the water district has
learned something from all the bad press and the knowledge that it caused
unlawful jeopardy to snail kites. (Audubon has been contemplating legal action
but as of this writing is pursuing dialogue.) Maybe Governor Scott, already
hugely unpopular even with his Tea Party, will serve but one term.
“One thing I’ve learned in this job is patience,” Gray told
me shortly before we went our separate ways.
I’m shorter on both patience and decades than Gray. But if
I’m around in 2021, I hope and expect to find: a cleaner Lake Okeechobee;
agriculture that doesn’t corrupt water quality, wildlife, recreation, and
political leadership; inflows and outflows that seep as well as gush; and even
more birds—including fledgling Everglade snail kites.
