Army Corps to Lay Out Plans for Upper Mississippi

After years of delay and scandal, the Army Corps of Engineers is getting ready to release its final
report on how to best manage the Upper Mississippi River. The report will influence policy on the
river for the next 50 years. The Great Lakes Radio Consortium’s Katherine Glover has the story:


It’s the job of the Army Corps of Engineers to help barges move up and down the Mississippi. The
Corps has channeled the river and dredged soil from the bottom to deepen it. It has built walls
along the sides, called levees, to prevent flooding. And its lock and dam system has converted the
river into a stairway of pools, allowing it to control the river’s flow.


The Corps has spent billions of dollars to build and maintain these systems. Critics say that these
expensive projects amount to huge subsidy for the barging industry. And they say these projects
are destroying the river’s ecosystem.


Dan McGuiness leads the Upper Mississippi River campaign of the National Audubon Society. He
says the damage to the river isn’t always obvious.


“People oftentimes think the river looks pretty good, and it looks not much different than it did 40
or 50 years ago, but most of the damage on the river is what you can’t see; it’s below the water.”


McGuiness is concerned that the Corps new plans will cause even more damage. But industry
groups want the Corps to build newer, bigger locks. Barges have doubled in size since the first
locks were built. To fit through, barges must now separate into two pieces and then reconnected on
the other side.


Chris Brescia is the President of MARC 2000, the Midwest Area River Coalition, a barge industry
group. During peak season, he says, the wait time at a lock can be over 24 hours.


“And remember, that’s at each lock. That’s not just at one lock.”


And there are 29 locks on the Upper Mississippi River.


In April, the Corps will release a study detailing how to improve the river. The Corps abandoned
an earlier version of the study after they were caught falsifying data to justify increased funding.
This time around, the Corps has promised to work with environmental groups and to look at
ecosystem restoration alternatives as well as navigation improvements. The study is sure to stir up
fierce debate about one of our country’s greatest water resources, and about how that resource, and
our tax dollars, should be used.

Manmade Islands Stir Debate

For more than one hundred years, man has made changes to rivers and lakes. Locks, dams, and redirecting waterways has raised water levels and increased river flows. One effect has been the near disappearance of islands that once provided habitat for fish, plants, and birds. Some groups are trying to rebuild those islands. But the concept of a man-made island is not universally accepted. The Great Lakes Radio Consortium’s Jonathan Ahl reports:

For more than one hundred years, man has made changes to rivers and lakes. Locks, dams,
and redirecting waterways has raised water levels and increased river flows. One effect
has been the near disappearance of islands that once provided habitat for fish, plants, and
birds. Some groups are trying to rebuild those islands. But the concept of a manmade
island is not universally accepted. The Great Lakes Radio Consortium’s Jonathan Ahl
reports:


Jim Baldwin is driving his small boat along an island in the Illinois River, the body of
water that connects the Great Lakes to the Mississippi River. He is an environmentalist
that has been watching this portion of the river for years, and likes what he sees. He’s retired now,
and spends most of his time either at his cabin on the riverfront just north of Peoria, Illinois
or working with environmental groups looking to preserve rivers and streams. These
islands are not natural. The Army Corps of Engineers made them ten years ago. Baldwin
says since then, it’s not uncommon for him to take his boat out and see fifty to a hundred
pelicans.


“Everybody tells me that until this island was built, they never even stopped here. Now
some of them stay year round.”


The Corps built the islands by dredging silt and sediment that had been clogging nearby
portions of the river. The theory is the manmade islands would provide a buffer from the
river flow, and create an area of deep water that could provide habitat for sport fish. It
would also provide a feeding area for migrating birds.


John Marlin is a researcher with the Illinois Department of Natural Resources. He says the
program has been a success.


“The islands stop the large waves that come across the lake and there is a calm area behind
the islands the waterfowl seem to appreciate. Also, the birds such as pelicans and alot of the wading birds are using
the islands as resting areas.”


Marlin says the islands are growing thick vegetation, and the soil dredged from the river
has proven to be free of any pollutants that are present in some river sediments.


But not all environmentalists sing the praises of manmade islands. Some believe these
new islands will suffer the same fate of the natural islands that are now gone.


Tom Edwards is the head of River Rescue, an environmental group focusing on rivers. He
says the man made islands are only a temporary fix:


“The islands are an illusion. All of the wonderful that they say are going to result from the islands are not going to result. We have 113 islands in the river right now, and it hasn’t
resulted from a single one of them. So let’s learn from what’s here right now. So they are
going to dig the water deeper around these islands and hope that’s going create deep water.
It will be very temporary. Deep water amounts to a silt trap.”


Edwards says it is just a matter of time until the sediment fills up the deep water areas created by the manmade islands. He says until there are significant changes in land-use policy that keep sediment from entering rivers, manmade islands will only be a quick fix.


But river activist Jim Baldwin says many states and local governments are starting to adopt
land use policies that will keep sediment out of the Midwest Rivers and streams. He also
says using dredged materials to create the islands will help alleviate the problem. He says most importantly, the manmade islands are getting the job done.


“It does two things. Number one is it provides the deep water that we need for fisheries.
The island itself will grow trees and habitats for all kinds of birds. It will do that. That’s what it’s all based on is those two things.”


While the debate over man made islands continues, the Army Corps of Engineers is proposing to build two more islands on the Illinois River in the coming years.

DAMS MAKE MAJOR FLOODS WORSE? (Short)

A recent study concludes that some of the flood control projects along the Midwest’s largest rivers might be making the severity of some floods worse. The Great Lakes Radio Consortium’s Lester Graham reports:

The study, published in the journal Geology, looked at the history of flood stages and river flows along portions of the Mississippi and Missouri rivers. It concludes that the dams, dikes, and levees constrict rivers so that when there are massive floods, such as on the Mississippi in 1993, they make the situation worse. Everett Shock is a professor at Washington University and one of the authors of the study.

“There needs to be some very clever thought on how to go about some differences in management practices so that we aren’t making large floods worse.”

The Army Corps of Engineers, which built and maintains the flood control projects along rivers, says the study is flawed because it doesn’t use updated data and it doesn’t consider the role that man-made reservoirs play in holding backwater during floods. The Corps also notes that before the flood projects, the rivers often damaged homes, businesses and property on a large scale, something that the Corps says rarely happens now.
