Note: This is the first
in a series of posts about environmental problems in South Florida related to
polluted Lake Okeechobee and its dangerously frail dike. I am a newcomer to both the problems and
the area, having become the owner of a condominium in Jensen Beach this year.
My hope is that fresh reporting on this old problem may help inspire concerted,
corrective action.
The Army Corps of Engineers committed
what should be regarded as an environmental crime this summer and fall,
flooding two of Florida’s most biologically rich estuaries with billions of
gallons of toxic, polluted water. Dolphins, endangered manatees, fish, oysters,
grasses and other marine plants suffered the consequences, and fishing and swimming
in the affected areas was forbidden because of high levels of dangerous
bacteria .
Take a look at these
pictures
to get an idea of what happened to the Indian River Lagoon, one of the two
estuaries.
Filthy water—
3 billion gallons a day at the peak in
mid-August--contaminated with runoff from farm fields and septic tanks, was
diverted east and west from huge Lake Okeechobee. The filth spread like a black,
underwater monster through the delicate lagoon.
It happened because heavy rains this past summer raised the
water level so high that the aged earthen dike holding in the lake was in
danger of failure. In late October, the Corps was still releasing a massive
amount to the lagoon: 765.2 million gallons a day.
The Indian River Lagoon is the most biologically diverse
estuary in the Continental United States. (An estuary is a body of water open to the sea where fresh
water from creeks and rivers mix with salty water that rushes in on the tide.) More
than 4,000 species of plants and animals and one-third of the world’s last
manatees live in the lagoon. They are
delicately adjusted to the constantly changing ratio of fresh to salt water. The
beauty of the lagoon is a major reason my husband and I chose recently to buy a condominium near
it.
The effect of the deluge of polluted fresh water from the
lake was dramatic. It dropped the salinity of the lagoon to zero and created a
massive bloom of algae as a result of all the phosphorus and nitrogen in the
water. These pollutants come from both farms and leaky home septic systems. Oysters
and sea grass beds died, and fishing stopped.
You’d think a discharge of pollution like this would be
illegal. Indeed, in the rest of the country, tiny spills can bring criminal
prosecution and big fines. But not
in this case. It is illegal to dump
polluted water into the Everglades, where flow from the lake should go. But there
is no law, federal or state, against these discharges into the estuaries. In
fact, they are considered necessary to protect people from a catastrophic
breach of the dike.
If this were the first time this has happened, you might
expect that immediate action is planned to correct the situation. Instead, releases
of polluted water happen roughly every ten years when heavy rains hit
the state and fill Lake Okeechobee to dangerous levels. “
Lake dump,” as the
Miami Herald
calls it, rushed into the lagoon in 2004 and 2005, after
hurricanes pounded Florida, and before that, in 1998.
“A Gun Pointed at South Florida”
Built of earth in the 1930s, the Okeechobee dike is a poster
child for neglected infrastructure in the United States. It is the most fragile
“dam” in the country and is in “grave and imminent danger” of collapse.
After New Orleans, Lake Okeechobee is the most vulnerable
area in the United States to damage from a Hurricane. (See the size and
location of the lake
here.
Lloyds, the British insurer,
reports
that the chance of failure of the dike is one in six in any given year without
continual intervention by the Army Corps to shore it up.
Most vulnerable are the 40,000 people who live in the
immediate vicinity of the lake and could be swept away if the dike bursts,
along with thousands of homes. But a burst dike could also contaminate the
water supply of the 5 million people who live in Palm Beach, Broward and
Miami-Dade Counties, and part of this area could be submerged. A burst could
also “irretrievably damage” the Everglades, according to expert reports.
Although it is named for President Herbert Hoover, the dike
was not built to the standards of Nevada’s Hoover Dam, for example. It was
built to control floods after a category 5 hurricane hit the lake in 1928,
killed 2,500 and caused immense property damage. But as south Florida
developed, the 730 square mile lake (half the size of the state of Rhode
Island) became the place to put all the water that was in the way of housing
developers and the sugar industry. For example, channels into the lake were
built to take in water from the Kissimmee River, which naturally flows to the
north and away from the lake. Now, Kissimmee water flows south into the lake at six times
the rate than it can be pumped out.
So this earthen dike is now being used as a dam to hold a
reservoir for sugar farms and as a tank for floodwaters. It is a giant cesspool.
And everyone knows it leaks. A 2006 report prepared for the
South Florida Water District describes portions of it as bearing “ a striking resemblance to Swiss
cheese.” Failure now would be “a
catastrophe for the whole of South Florida,” says the report. One of the
experts who studied the situation calls the dike “a gun pointed at South
Florida.”
This year, the Army Corps completed a $220 million
overhaul of the most vulnerable stretch of the dike, but at the current pace of
repair work, bringing the dike up to dam standards
will take another decade or
more.
That means that it is just about inevitable that polluted
water will again flood the lagoon.
Time to Redirect Government Spending
The dike offers a perfect example of how our country has
been putting off fixing our infrastructure while spending trillions on our
military and the arms industry, and billions every year to subsidize Big Oil
and Big Agriculture. The interconnected water problems in South Florida have
been studied over and over again for the past 30 years but little gets done.
Politicians whine about spending the money, and the status quo suits developers and the sugar industry
just fine, thank you.
Meanwhile, the
Everglades remains shortchanged of the water that used to flow south naturally
from the lake, and the two estuaries periodically become sewers for the lake’s
dirty water every time it rains heavily. (To the west, it is the Caloosahatchee River and Estuary that gets
the lake dump.)
Fixing these problems will require a concerted, comprehensive
and cooperative effort by the state and federal governments, and by all the
concerned environmental and other organizations that have been working on
different pieces of the problem.
It will cost billions of dollars. And at the moment, it
looks like federal and state taxpayers will have to bear that cost, and not
other players like the sugar plantations that have been polluting the
Everglades for decades.
Stay tuned. In my next post, I’ll take a closer look at Big
Sugar and how easily it maintains
its grip on Florida’s politicians and legislators. ##
