The head of the Army Corps of Engineers has sent Congress a $778 million plan to fortify an Illinois waterway with noisemakers, electric cables and other devices in the hope that they will prevent Asian carp from reaching the Great Lakes, where the aggressive invaders could leave other fish with too little to eat.

Lt. Gen. Todd Semonite on Thursday approved the plan to install defenses at the Brandon Road Lock and Dam near Joliet, Illinois, about 40 miles from Lake Michigan. The site is a crucial choke point in an aquatic pathway between the and the carp-infested Illinois River.

The plan represents a compromise between proposals to erect barriers that would seal off Lake Michigan from the river and less drastic measures such as stepped-up .

Environmentalists and states including Michigan had argued for physical separation, while Illinois and Indiana contended that it would disrupt cargo shipping and that a Chicago-area electric barrier was keeping the carp at bay.

Although only a few live Asian carp have been found past the barrier, the fish's DNA has turned up there as recently as April, when were taken from Chicago's Lake Calumet. The Corps says the leading edge of adult bighead and silver carp—the most feared of several Asian species because they gorge on plankton that other fish need—is about four miles from the Brandon Road complex.

"The Brandon Road project is the only shot we have to get additional protections in place to stop the carp," said Marc Smith of the National Wildlife Federation. "It will significantly reduce the risk."

The plan calls for installing a gantlet of technologies intended to repel approaching fish, including additional electric barriers and underwater speakers that would blast loud noises, plus an "air bubble curtain." A specially designed "flushing lock" would wash away carp that might be floating on the water as vessels pass through.

Semonite's endorsement came more than five years after the Army Corps offered a series of options for blocking the carp's advance.

It's now up to Congress to decide whether to authorize the project and provide most of the funding. A pending House bill recommends $3.8 million for preconstruction, engineering and design work in 2020. The expected completion date is March 2027.

"With the Asian Carp on the doorstep of our region's most vital natural resource, we have a small window of time to stop this invasive species before it inflicts irreparable damage on our Great Lakes and our $7 billion and equally important tourism industry," said Rep. Marcy Kaptur, an Ohio Democrat who chairs the Appropriations Subcommittee on Energy and Water Development.

Republican Reps. Paul Mitchell and Bill Huizenga of Michigan also pledged support.

Bipartisan teamwork will be essential, particularly given the plan's escalating cost, said Molly Flanagan of the Alliance for the Great Lakes.

A draft released in 2017 estimated that the project would cost $275 million. The final version put the price tag at $778 million, and that would be under an "expedited" scenario in which the various technologies would be installed at the same time. It could reach $832 million under an alternative "phased" strategy, spokesman Allen Marshall said.

Another key will be getting financial support from Great Lakes states. The Army Corps generally requires non-federal partners to pay 35 percent of a project's construction costs, although Congress could waive some or all of the requirement.

Illinois Gov. J.B. Pritzker last month authorized his state's cooperation with initial phases of the program but said he wouldn't commit to long-term support without efforts to limit costs and contributions from other states.

Sens. Dick Durbin and Tammy Duckworth, both Illinois Democrats, said Friday that they would seek congressional approval "under a cost-share agreement that will ensure Illinois isn't left footing the bill for a project that will benefit the entire Great Lakes region."

This is silly. The Asian Carp is a food fish, so why aren't they using it for food?

"Asian carp have been a popular food fish in Asia for thousands of years. Some recipes are specifically for carp such as Tángcù Lǐyú (sweet-and-sour carp) and Koikoku (thick miso soup with carp). However, many people in North America do not distinguish the various Asian carp species and see them all as undesirable food fish due to their perceived bottom-feeding behavior, while, in fact, only some species are bottom-feeders, and even the bottom-feeding species such as the common carp, a highly bony species which was introduced to North America from Eurasia in the 1800s, are important food fish outside North America.[8]"

so why aren't they
invasive species can be destructive to existing food sources as well as the ecosystem

two searches below, one vague and one specific, answering your question with science, observation and continually updated fact versus your speculation about the topic based upon your ignorance and ASSumptions because other cultures eat carp.

Note: Bacon, liver, fermented cabbage, aged fish and egg, smoked and salted meats, tripe and haggis are also culturally accepted as a food product but not universally accepted as "food" in every culture as well

You are Ridiculous, as usual. A good majority of Americans are willing to try new foods such as carp if it is advertised as nutritious and good tasting, instead of simply an Asian invader that is killing other types of fish in the GL area. The fishing industry is concerned with popular eating fish at the moment.

@Egg
as usual, you ignore facts and science to promote your opinion and beliefs
A good majority of Americans are willing to try new foods such as carp
supposition and without supporting evidence, so this is your OPINION
http://www.auburn...ion.html

I've live in "fishing country" and not one of the locals will try it - not one. not even the most avid fishermen

I have to visit the local Japanese or Chinese communities and special request Carp if I want it
if it is advertised as
so, you didn't actually read any of those links, then?

the science didn't "advertise" it - they produced facts which were observed and validated

Science:
it's not some PR campaign
The fishing industry is concerned with popular eating fish at the moment
how many of those studies in my above links were written by the fishing industry?

We do not have to eat this carp
it can be used for animal feed
once a market is there for fishermen to sell this carp
These carp will make their presence scarce

isn't the point

you're attempting to spin a positive for an invasive species - save the optimism for a church

it isn't always a good thing, especially with no natural predators and no controls

we create the predators

There is feeling of a lone soul

Those great deeds long past
No longer fit this pristine anew

Is of long past

@gran

yes and no
allowing the invasive species into the habitat destroys existing stock as well as potentially affects other ecosystems by killing their food sources, etc

it can also be far worse considering the long term ramifications

the best choice would be to create farms in sequestered waters that do not allow them to spread to raise said invasive species, not allow them to destroy the local ecosystem
A more quiescent
just busy writing up about the local lunatic asylum found here on PO

At least you'll be famous in the current incarnation, right?

This pristine anew A more quiescent place
A quiet place just like P.W used to be
@gran, A more quiescent


@Stumps, just busy writing up about the local lunatic asylum found here on PO

At least you'll be famous in the current incarnation, right?

For simply Stumps
If you experienced the embers of P.W
You would have experienced this quiet quantum breeze
That seems to be blowing once again
