Army Corps of Engineers report lays out 8 ways to stop asian carp

Now it’s up to Congress to decide if they’ll devote $18.4 billion for the strategy recommended by those scientists.

The strategy most Great Lakes scientists seem to prefer to keep Asian carp from entering Lake Michigan near Chicago would cost taxpayers $18.4 billion and take 25 years to build, according to a long-awaited Army Corps of Engineers study released on Monday.

Now it’s up to Congress to decide if they’ll give those scientists what they want.

The Toledo area and other parts of western Lake Erie between Monroe and Sandusky — the heart of the Great Lakes region’s $7 billion fishery — have a lot at stake with the decision, from fishing jobs to tourism opportunities.

Silver Asian carp and silver bighead carp — the two most destructive of four fish species commonly known as Asian carp — have been encroaching on Lake Michigan for years now after escaping southern fish hatcheries flooded in 1995 by the Mississippi River.

The fish have migrated upstream against the river’s current and have colonized tributary rivers including the Wabash and Illinois.

The Wabash poses a direct threat to the Maumee River, the region’s most productive for fish spawning, through the risk that Eagle Marsh, a wetland near Fort Wayne, might flood and temporarily connect the two watersheds. That would provide carp a pathway through a chain-link fence.

But the most likely flash point has been in Chicago, where the Chicago River’s flow was reversed a century ago to flush wastewater out of the city. As a result, Lake Michigan has been connected to the Mississippi through a series of canals and natural streams.

Disconnecting the Lake Michigan and Mississippi watersheds is a concept pushed by countless Great Lakes fishery biologists, university professors, and policy experts, including the Ann Arbor-based Great Lakes Fishery Commission, founded by the United States and Canada in 1955 to combat invasive species.

The great unknown was the price.

A 2012 engineering analysis issued by the Ann Arbor-based Great Lakes Commission, a regional board funded by the eight Great Lakes states and two Canadian provinces, and the Chicago-based Great Lakes and St. Lawrence Cities Initiative, funded by Great Lakes-area cities, estimated watershed separation’s cost at $9.5 billion.

But the corps of engineers, in its report to Congress, said separating Lake Michigan from the Mississippi would cost nearly twice as much — $18.4 billion — and take a quarter of a century to do.

One of the two key differences between the studies is that the corps used a 500-year flood event for its proposal, whereas the consultant for the Great Lakes Commission and Great Lakes/?St. Lawrence Cities Initiative used a 100-year flood. The former is more conservative, based on conditions only likely to occur, on average, once in 500 years.

Dave Wethington, the corps’ project manager, said the corps believed it was more appropriate to base the design around a 500-year flood to ensure Chicago-area residents have safeguards against flooding and polluted drinking water.

He acknowledged there is a “very real possibility” the Great Lakes fishery could be changed in the 25 years it takes to complete such a project.

“Can we do it quick enough [to prevent Asian carp from colonizing the lakes]? The answer is, nobody knows,” Mr. Wethington said.

The corps report was originally slated for release at the end of 2015. It was submitted to Congress nearly two years ahead of time after several Great Lakes congressmen accused the agency of dragging its feet and shepherded legislation speeding up the study’s schedule.

The report contains eight options, one of which calls for the status quo. Six call for physical barriers or construction work ranging from $7.8 billion to $18.4 billion. One calls for $68 million a year for nonconstruction measures, including public education, tougher enforcement of boating laws, and use of poisons to kill carp.

Mr. Wethington said a combination of options is possible, but the corps believes none offer a sure-fire guarantee, not even a complete hydrological separation.

Congress needed the corps’ report before it could consider such a massive project, said Marc Gaden, a Great Lakes Fishery Commission spokesman.

“I feel good about the fact we can now get on with it,” he said of the congressional review.

Area congressmen had much to say about the report but did not commit themselves to any of the options.

U.S. Rep. Marcy Kaptur (D., Toledo) “has always favored hydrological separation and still does,” according to Steve Fought, her communications director.

“The problem, of course, is getting the political will of Congress to support hydrological separation, because it’s going to cost a lot of money,” Mr. Fought said.

He said Miss Kaptur has a sense of urgency about the issue.

“To her, it’s a matter of equity for Lake Erie’s fishing and tourism industries,” Mr. Fought said.

U.S. Rep. Bob Latta (R., Bowling Green) could not be reached for comment.

U.S. Sen. Debbie Stabenow (D., Mich.), who has supported a hydrological separation in the past, stopped short of embracing the $18.4 billion option in a conference call with reporters. She said, however, the most obvious choice to cross off the list is no action.

“The biggest disappointment is there are seven options here other than the status quo,” she said, explaining that she had hoped for a little more direction from the corps.

U.S. Sen. Rob Portman (R., Ohio) agreed, saying he wished “the U.S. Army Corps of Engineers’ report would have identified the best option for preventing the spread of invasive species to the Great Lakes.”

Lake Erie, Senator Portman said, is a backbone to Ohio’s economy and helps support 100,000 jobs.

U.S. Sen. Sherrod Brown (D., Ohio) said keeping Asian carp out of the Great Lakes and the Ohio River “is about safeguarding our economy and the livelihood of thousands of Ohioans.”

The corps is taking public comment on its report through March 3, and has set six public meetings across the Great Lakes basin — plus one in St. Louis — for discussion.

Closest to the Toledo area will be meetings Jan. 16 in the Cleveland Public Library, 325 Superior Ave. NE, Cleveland, and Jan. 21 at the University of Michigan League, 911 N. University Ave., Ann Arbor.

Both sessions will run from 4 to 7 p.m.

I for one, would like to have seen the 'Corp of engineer's " get moving---yesterday--- on this project rather than trying to debate the fish to death.


Personally, I'd get moving with the poison, than add something that has worked pretty well across the century's on various people and animals: A bounty.


Even, at the relatively cheap bounty of say a buck or 2 bucks per fish. I'll bet, we'd see a ton of carp taken from the rivers. Would that be enough ? No. But a start is better than trying to debate the fish to death.

mikeylikesit

that kind of common sense will get you nowhere with these people.

The state of Louisiana does this with the nutria rat problem, $5 bounty on rats that are killed. Bring the tail get paid.

Dr. Information

18 billion, that of which only 2 billion will be used for this invasion, the rest will be blown elsewhere.

That's right. Politics at work. The fish are already in the lakes in small numbers now.

kURTje

sOO cliFF. You read earlier posts? Earth fOOd, pet fOOd, hog fOOd tOO? To bad "they" wouldn't let US get agrEEsive on those fish. We have real answers to this problem.

I can't say for sure. Yet, I do believe, that our idea's combined would go a heck of a long way towards if not solving, at least denting the hades out of the carp problem.

To bad as Twain noted " Common sense ain't so common "

hit the road jack

All this stirring up about fish when the corps of engineers have spent tens of billions of dollars in New Orleans and see what happens every year there? they have squandered so much time and money its pathetic.

If there were a way to get high off of Asian carp, we wouldn't be having a problem with their overpopulation.
