Legal attempts to force Asian carp action hit another barrier
A group of states wanting to wall off Asian carp entry into the Great Lakes via the Chicago Area Waterway System have run into another legal stumbling block.
In December, The Washington Post reports, a federal judge threw out a lawsuit brought by Michigan, Wisconsin, Minnesota, Ohio and Pennsylvania.
Those states want to force the U.S. Army Corps of Engineers to physically separate the Great Lakes from the Mississippi River system, where Asian carp have spread and already wreaked ecological havoc. The two water systems are currently connected via a network of rivers and man-made canals in the Chicago area.
The decision is the latest in a string of legal defeats for states seeking a way to require immediate action by the Army Corps. The Corps is conducting a study on how to prevent the spread of Asian carp and other invasive species between the Great Lakes and Mississippi River.
Earlier this year, too, the U.S. Congress passed legislation requiring the Corps to release a study on Asian carp prevention by 2013. That study will include options for preventing carp from entering the Great Lakes via the Chicago Area Waterway System as well as other possible points of entry in the region.
