A new study claims the U.S. Government is losing billions of dollars by allowing farmers to grow
genetically-modified crops. The Great Lakes Radio Consortium’s Jonathan Ahl reports:
The study from the British Soil Association reports the U.S. has increased farm subsidies by 12
billion dollars over the past three years to make up for lower exports. Many European countries
will not allow the import of genetically-modified food. They say it hasn’t been proven to be safe
for human consumption. But U.S. farmers refute the report.
Leon Corzine is a Central Illinois corn and soybean farmer. He says a report criticizing the economics of genetically-modified
crops is nothing more than propaganda.
“If bio-tech crops – just like any other item – if it is not economically viable, they don’t last and
we don’t use them. That’s how I operate on my farm.”
Corzine says there are so many variables in the agriculture industry that it’s impossible to blame
one thing for higher subsidies. He also says while some European countries are turning away
U.S. grain, other countries are increasing their import levels.

A recent study concludes that some actions of the Army Corps of Engineers might be causing more, rather than less damage during major floods on rivers in the Midwest. The study by two Washington University professors found that wing dams which jut out into the river could cause big floods to rise even higher. The Great Lakes Radio Consortium’s Lester Graham takes a closer look at this study:
The Mississippi and the Missouri rivers are two of the major arteries for barge transportation in America. Millions of tons of grain, and raw materials are floated up and down the rivers each year. It’s the Army Corps of Engineers’ job to keep the rivers open to barge traffic. The Corps has been doing that job for the past 150 years. But since the 1930’s that effort has taken on immense proportions. Huge dams hold back the river, keeping the water high enough for the barges to travel up and down-stream. Big earthen dikes, called levees, wall in the rivers, keeping them from flooding farms and towns, but also keeping the water from reaching the natural flood plain. Robert Criss and Everett Shock studied flood levels and the effects of the Corps of Engineers projects. Criss says those dams and levees alone might be enough to disrupt the flow of the river and cause flood stages to be higher.
“But the other component is these structures called wing-dams which are jetties of rocks that project out perpendicularly into the channel. For high-flow conditions, these act something like scale in a pipe. They impede the flow, restricting the channel. That slows the velocity of the water down and that also makes the flood stages higher.”
The purpose of wing dams is to force the current to the middle of the river to scour out the navigation channel to keep it open for the barges. Researcher Everett Shock.
“So, they do the job they’re intended to do. It seems that there’s an unintended–perhaps unintended consequence of all these constructions along the river that shows up when we have a big flood and makes it to –on the basis of our study– makes these big floods worse.”
Criss and Shock say their study finds that since these flood control projects have been erected, there have been more big floods, such as the one in 1993 that flooded the Mississippi and some of its tributaries for most of the summer. Robert Criss.
“The fact is, before World War II, a flood stage of 38-feet is very rare and now it happens every five years.”
But not everyone agrees with the methodology used by the researchers. The
Corps of Engineers dismisses the researchers’ study, saying they used flawed data. Corps officials point to a study at the University of Missouri – Rolla. That study compared the 19th century method of measuring a river’s flow by timing how fast floats moved in the current to the methods used today. Dave Busse is a scientist with the Army Corps of Engineers. He says the original stream flow measurements –the ones Criss and Shock used— were inaccurate.
“The flows were over-estimated by 30-percent using this float measurements rather than the measurements than we use today.”
Criss and Shock are skeptical of new numbers that the Corps prefers. Saying it seems awfully convenient for the Corps because changing the numbers makes the historic floods look smaller and therefore makes the 1993 flood look unprecedented. Criss and Shock say based on the original records, there was as much water in past floods as in the 1993 flood but lower water levels. Criss and Shock say the difference between then and now is that the Corps’ big dams, levees, and wing dams constrict the river’s flow and make floods higher.
The Corps, however, has other criticisms of the Criss and Shock study. Dave Busse says the researchers ignored the role of the Corps’ reservoirs in the rivers’ watersheds. Busse says the reservoirs hold back water that would otherwise be part of a flood. And Busse says, another flaw is the researchers conclusions about wing dams. The Corps says the wing dams force water to deepen the channel and increases the flow of the river.
“So, what we have is the same –it’s a re-shaped river, but its carrying capacity is actually higher now. We can actually carry more water at the same stage. The river got deeper, therefore this conclusion that they’ve made is wrong.”
The Corps says there’s more to managing the river than the researchers have considered. Criss and Schock, meanwhile, say their study is not the first to be dismissed by the Corps of Engineers. They say other studies have found similar results, but the Corps dismissed them as well.
Environmentalists have been arguing for decades that levees and dams keep floodwaters from spreading out on their natural flood plains and cause higher flood levels. The Criss and Shock study adds to their arsenal of arguments to change the way the rivers are managed. But most environmentalists concede that we’ve become somewhat dependent on the Corps flood control projects. Chad Smith is with the environmental group,
American Rivers.
“In most ways both of these camps are right. The Corps is right that putting some of the structure in has helped to reduce the kind of annual flood events that always happen on a big river like this, but what they unfortunately have done is to exacerbate what happens when you have bigger floods and the wing dams and the levees and the dams themselves all are part of that.”
The Army Corps of Engineers says it’s reviewing its way of managing rivers in light of the 1993 flood. But they also note that while flood stages might be higher more often than they were in the 19th century, most of the time those floodwaters remain behind the floodwalls and levees, protecting the communities from high water, and the Corps says in the end, that’s the only fact that really matters.

Since September 11, the U.S. government has been closing security gaps in aviation. But maritime officials warn that security on our Great Lakes is even less certain. Recently the U.S. Coast Guard held an international conference in Cleveland on Great Lakes security. The Great Lakes Radio Consortium’s Karen Schaefer reports:
On September 11, about 55 commercial U.S. and foreign freighters were cruising the Great Lakes and the St. Lawrence Seaway. Even as the nation’s airports were being closed, U.S. Coast Guard officials were ordered to stop and search those vessels. It took two days for the search to be completed. Commander James Hull heads the Coast Guard’s 9th District, which oversees shipping in the Great Lakes region. He says that action alerted the Guard to a serious problem.
“Didn’t know exactly where all those ships were. AIS system solves that.”
AIS is a new communications protocol now being developed by the International Maritime Organization. Using a global positioning system, ships equipped with AIS will be able to transmit their exact location – and identity – to other vessels and maritime authorities. But so far, the system hasn’t been widely adopted. And that’s just the first security risk the Coast Guard discovered.
“We had people asking how you drive the ships and how you get training?”
As the weeks went by, the list of vulnerable areas grew. Nuclear power plants located along the lakeshore, ports and harbors, bridges, tunnels, and locks. Ships carrying hazardous cargo and those from countries with known terrorist links. And then there are the thousands of cargo containers shipped daily from ports around the world.
“Ambi here?”
27-hundred reservists were called up to assist the Coast Guard in patrolling and monitoring sensitive areas. The federal government allocated more than 220-million dollars in additional funds. But four months after the terrorist attacks, more than 50-percent of the Coast Guard’s efforts are still being spent on security. The Guard’s original mission – to guide maritime operations, assist in search and rescue, and help clean up environmental problems – has been largely overshadowed. Nonetheless oversight of commercial shipping is part of the Coast Guard’s job. Goods shipped on the Great Lakes are worth more than 742-billion dollars a year to the U.S. economy. Most of those goods and raw materials enter or leave the Great Lakes in bulk shipments and in containers that are off-loaded directly from ships. Dr. Steven Flynn is a former Coast Guard Commander and a Senior Fellow with the National Security Studies Program at the Council on Foreign Relations in New York City. He says a disruption to Great Lakes shipping could have wide-reaching consequences for the entire U.S.
“And so if we have another incident…we’re still extremely vulnerable, we’re still not out of the woods on this here – that if it happens in those sectors, my fear is not just the consequence of seeing another sight like I saw on September 16 after the attack, but also is the disruption that would come from happening within those sectors.”
Those disruptions could also severely hamper the Canadian economy, which ships much of its grain and steel through the Great Lakes. As the U.S.’s largest trading partner and nearest neighbor, Canada already shares jurisdiction over Great Lakes resources through the International Joint Commission. Now government officials on both sides of the border say it’s more important than ever to work together.

John Adams is the Canadian Coast Guard Commissioner. He says the U.S. and Canada have recently signed a 30-point plan to jointly improve security on the Great Lakes, while allowing trade to flourish. Both governments have already instituted new 96-hour arrival notification requirements for vessels coming into North American ports. And they’ve extended the international maritime borders from 3-miles to twelve. But there are plenty of other new security plans yet to be adopted, ranging from identity cards and background checks to a point-of-origin system for clearing container cargo. And both countries will be sending representatives to the International Maritime Organization conference in London, where organizers hope to move ahead with new standardized strategies to keep global trade secure.

Ponds and lakes in some areas of the Midwest are the
lowest they've been in more than 35 years. Some cities are implementing
water use restrictions. Some farmers are concerned there's not enough
subsoil moisture for crops to use during the hot summer months.
The farm belt is short on rain. Since last summer, much of the
Midwest has been getting below normal rainfall. Lakes and rivers are
low. Long-range weather projections are not promising. Farmers and
communities that rely on reservoirs are concerned. The Great Lakes

It doesn’t happen very often, but for the last year, a republican
governor, the farming community, and environmentalists have been working
together to protect endangered wetlands, by taking certain farmlands out
of production. But now, a new federal proposal could be separating the
groups. The Great Lakes Radio Consortium’s Jonathan Ahl has the story:
