Appeals court won’t close Chicago locks over carp

AP Wire • Jul 21, 2015 at 11:05 AM

The 7th U.S. Circuit Court of Appeals in Chicago became the latest of several courts to turn down a plea from five states for immediate shutdown of the locks and a quicker timetable for other steps to halt the carp’s northward march from the Mississippi River toward Lake Michigan, from which it could spread to the rest of the Great Lakes. The U.S. Supreme Court twice has rejected the request from Michigan, Minnesota, Ohio, Pennsylvania and Wisconsin. Federal District Judge Robert Dow in Chicago did likewise last December.

The states have a pending lawsuit that calls for permanently severing a century-old, man-made link between the Mississippi and Great Lakes drainage basins. They had sought a court order to close the locks, which could provide a pathway to Lake Michigan for the carp, while their suit works through the courts. With the appeals panel’s ruling, that prospect appears remote.

Significantly, however, the three-judge panel disagreed with Dow’s conclusion that the states appeared to have little chance of succeeding in their lawsuit. Dow had acknowledged a carp invasion could harm the Great Lakes but said the states hadn’t shown it was likely or imminent. He said flooding and economic damage from closing the locks would do more damage to Chicago-area businesses and homeowners than “the more remote harm associated with the possibility” of Asian carp becoming established in the lakes.

In their opinion, Judges Daniel Manion, Diane Wood and Ann Claire Williams said they were “less sanguine about the prospects of keeping the carp at bay.”

“In our view, the plaintiffs presented enough evidence at this preliminary stage of the case to establish a good or perhaps even a substantial likelihood of harm — that is, a non-trivial chance that the carp will invade Lake Michigan in numbers great enough to constitute a public nuisance,” the judges said.

The Obama administration has pledged more than $120 million for a wide-ranging strategy to keep the carp out of the lakes. Because of those efforts, requiring immediate actions such as lock closure “would only get in the way,” the judges said.  “We stress, however, that if the agencies slip into somnolence or if the record reveals new information at the permanent injunction stage, this conclusion can be revisited.”

The five states could take their request to the full 7th Circuit court or try again before the Supreme Court. No decision has been made, said Joy Yearout, spokeswoman for Michigan Attorney General Bill Schuette.
