Conservation and wildlife groups asked a federal court for summary judgment in their lawsuit against the U.S. Army Corps of Engineers, alleging recent Mississippi River flooding could have been avoided with better management of the Cairo-to-St. Louis stretch. The groups want more detailed environmental reviews that could slow Corps projects.
The article notes the river carries 57% of U.S. corn exports and 59% of soybean exports.
