A federal judge may dismiss a lawsuit filed by Michigan and other Great Lakes states, over Asian Carp.
The judge dismissed the claims, by Michigan and four other states, but did say they can amend the lawsuit.
The states will have until January 1st to file amended claims against the Army Corps of Engineers.
The lawsuit is seeking an order, requiring the Corps to create a physical barrier in waterways that connect Lake Michigan to the Mississippi River.
This would help prevent Asian Carp from getting into the Great Lakes.
The judge says the action demanded by States is outside the Corps' authority.
