Crews in Chicago are on the hunt for Asian carp this week. The term Asian carp refers to two species: bighead and silver carp. The crews are looking for the carp in Lake Calumet, which is linked by a river to Lake Michigan. Asian carp have been found in the rivers that feed into Lake Michigan from Illinois.

John Rogner is the assistant director of the Illinois Department of Natural Resources. He says they’re looking for live carp after finding carp DNA in Lake Calumet.

He says it could mean there are live Asian carp in the lake.

“But there are some other possibilities. One is that there is DNA that comes upstream from downriver from boat hulls; it might be coming from restaurants in parts of Chicago that come out through the storm sewers.”

Some restaurants in the city serve Asian carp, so waste water could contain DNA from the fish. Rogner says people could also be releasing live carp into the lake, even though that’s illegal.

He says so far this week, they have not found any live bighead or silver carp in Lake Calumet.

State officials say they’ve discovered a virus for the first time in wild fish in Michigan. It’s called koi herpesvirus.

Gary Whelan is with the Michigan Department of Natural Resources.

He says the virus might have contributed to the death of several hundred common carp in Kent Lake last June. Whelan says the virus is known to affect common carp, goldfish and koi. And it can be fatal.

The Environmental Protection Agency is asking the company responsible for last year’s oil spill in the Kalamazoo River for information they say is missing. Last summer an Enbridge Energy pipeline ruptured, releasing more than 840,000 gallons of tar sands oil. Cleanup is still underway.

Last spring after the snow and ice melted, cleanup efforts on the Kalamazoo River really ramped up. The EPA came up with a plan to monitor air quality. The agency directed Enbridge to collect air samples to look for contaminants that could have been stirred up during the spring cleaning. Enbridge also was supposed to collect weather data so the EPA knew the conditions when the samples were taken.

Ralph Dollhopf heads EPA’s Incident Command for the Enbridge spill. He says some of that weather data is missing.

“It’s not necessarily a bad thing but we want to make sure that we understand the complete situation.”

Dollhopf says they’re asking Enbridge to supply the missing data or explain why it’s missing.

Marshall resident Susan Connolly says she’s disappointed, but not surprised the data Enbridge is responsible for gathering could be missing.

“That would be just like letting a pedophile babysit a child. I mean why would you let the person that caused the pipeline to spill to be the ones to monitor?"

The EPA oversees the cleanup.

An Enbridge spokesman says the company has not received the EPA’s notice yet so he declined to comment for now.

Michigan officials say a fish virus may have contributed to a June fish kill of 300 to 500 common carp in
Kent Lake.

The state Department of Natural Resources announced Wednesday that samples taken from the lake in Livingston and Oakland counties detected the presence of koi herpesvirus.

State officials say it's the first time the virus has been found in wild fish samples in Michigan. It was detected in a private koi pond near Grand Rapids in 2003.

The DNR says the virus has been seen before in large-scale common carp die-offs in Ontario, Canada, in 2007 and 2008.

The virus affects common carp, goldfish and koi. The state says there are no human health effects.

For fifty years Canada and the U.S. have been battling an eel-like creature across the Great Lakes. Sea lampreys are parasites that drill holes in fish to feed on blood and body fluids. They often kill the fish. The sea lamprey was one of the first invasive species to arrive in the lakes, and it’s the only invasive to be successfully controlled by humans.

But in recent years, the lamprey has been getting the upper hand in the struggle. As Peter Payette reports there might be more setbacks in the near future:

If you’re on a lamprey control team you get to see all the prettiest streams and rivers in the Great Lakes. That’s because lampreys like clean water.

“Part of our problems recently have been some of the streams that were too dirty to harbor lampreys have been cleaned up and now we have lampreys in parts of the Saginaw River. We never had lampreys in that up until 15 or 20 years ago.”

Ellie Koon supervises one of the U.S. Fish and Wildlife treatment teams. They spend the warm months killing young lampreys by the thousands.

They treat rivers using a chemical called lampricide. It’s a poison that rarely hurts other fish. In fact, during a treatment the fish get a feast they normally wouldn’t. Young lampreys look a bit like worms at this stage and stay in the mud. But when they’re poisoned they swim out where fish can grab them.

Ellie Koon and one of her team members, Hank Cupp, say fish and other animals in the river pig out.

“You can almost hear the fish burping the day after we treat. You can see them swimming around with lampreys hanging out of their mouths that they can’t swallow.”

Three non-profit organizations are asking a federal judge to let them weigh in on a proposed settlement between a private developer and Saugatuck Township.  Both parties have agreed to the deal, but a federal judge must approve it. The agreement would resolve a longstanding land-use case.

It happened a year ago. An oil pipeline owned by Enbridge Energy spilled more than 840,000 gallons of tar-sands oil into Talmadge Creek which flows into the Kalamazoo River.

People were evacuated, the Red Cross set up shelter, and officials were wondering if the spill might reach Lake Michigan (it never did).

I was skeptical when Enbridge put out a press release that said that the oil was all cleaned up, so I went to a spot along the river near Battle Creek. I went with a group that picked up gobs and gobs of oil and video taped it.

The news story Acker saw was published in August of last year. She told us that her chance to visit the river came this past spring when activists from the Yes Men  contacted her about a planned media hoax to draw more attention to the Enbridge oil spill.
