High court again stays out of big fish dispute
The Supreme Court for a third time has turned aside an urgent appeal from Great Lake states to close Chicago-area shipping channels so invasive Asian carp won't have a doorway into the world's largest freshwater ecosystem.
The justices Monday turned aside without comment another request for intervention, the latest chapter in a nearly century-old dispute involving six Midwest states and the Canadian province of Ontario.
At issue is a direct challenge to Illinois' complex water diversion and sewage disposal network, which some predict will inadvertently allow the non-native fish to enter Lake Michigan. Some environmentalists and lawmakers fear an economic and ecological disaster if the creatures breach man-made barriers. And there are concerns the fish may have already slipped past locks and entered the massive freshwater bodies of water.
