What Does Budget Proposal Mean For Invasive Species In The Great Lakes?

Researchers are trying to keep Asian carp out of the Great Lakes. And Lake Michigan near Chicago is on the front line of that fight. But budget cuts proposed by President Donald Trump could limit their work. 

As Chuck Quirmbach of Wisconsin Public Radio reports for Great Lakes Today, President Donald Trump ’s 2018 budget plan eliminates $300 million in funding to restore the Great Lakes. The plan has sparked concerns among environmentalists, because a lot of that money is being spent to protect the lakes from a voracious fish known as the Asian carp.

Some varieties, like the Bighead and Silver carp, grow to a fearsome 100 pounds and eat their weight in plankton every day. That leaves much less food for other fish. And with Asian carp spreading out in the United States, they’re common in the Mississippi and Illinois river systems. That’s why the battle to control them is being fought near the southern tip of Lake Michigan.

"We're the defensive line in preventing any future movement toward the lake of the fish,"

says Chuck Shea of the U.S. Army Corps of Engineers. He supervises a project that has already spent neatly $18 million from the Great Lakes Restoration Initiative for an underwater carp barrier. It's is in the Chicago Sanitary and Ship Canal near Romeoville, Illinois, about 40 miles southwest of Chicago.

At the bottom of the canal, steel electrodes create a pulsing electric field to deter carp from entering. The Corps of Engineers is upgrading the original barrier, one of three at the site. Shea says the work will strengthen the system.

"We've learned that the power levels that the demonstration barrier can operate at, limit its effectiveness. It's effective on larger fish, but it is not effective on smaller fish. So, by upgrading it, we can make it more effective on a wider range of fish."

Construction won't be affected by Trump's plan to eliminate the $300 million in the Great Lakes Restoration Initiative. But another $500,000 for a follow-up study is in doubt. That study would look at ways to Asian carp from being dragged or pushed through the barrier by barges.

Other agencies that use federal funding might also need to halt their work, or to look elsewhere for money.

"Great Lakes Restoration Initiative dollars are critical to the effort to keep Asian carp out of Lake Michigan,"

says Molly Flanagan of the Alliance for the Great Lakes.

"Funding from the Great Lakes Restoration Initiative goes to the Illinois Department of Natural Resources, to help with their harvesting effort to reduce population and the pressure that fish experience to move closer to Lake Michigan. Funding for the Great Lakes Restoration Initiative goes to agencies like the U.S. Geological Survey and the Fish and Wildlife Service that are doing different studies to find out what technologies might be useful in the battle against Asian carp."

And, Flanagan says, if the pot of money goes away, it would be tougher to get funding for stronger protections 20 miles downstream from the barrier, at the Corps of Engineers Brandon Road lock and dam.

Environmentalists want more safeguards at Brandon Road, which is about 10 miles from the leading edge of the Asian carp invasion.

But the Trump administration is delaying the release of a study on carp control options. That’s good news to Lynn Muench of the American Waterways Operators.The tug and barge trade group says additional structures at the lock could slow commerce. The group supports federal money for some research and for harvesting carp from the Illinois River, but Munch says other spending should get a close look.

"That's why you make a budget,” she says. “You look at everything and see if the cost-benefit is there. I would say that's true of everything in the federal budget.''

A bipartisan coalition in Congress backs the restoration initiative, so Trump may not be able to zero out the program. Congress can modify Trump's budget plan. But environmentalists say a big reduction in spending could still hurt efforts to halt the Asian carp.
