A new lawsuit says opening a spillway as a flood-control measure in 2019 sent polluted fresh water from the Mississippi River into the Gulf of Mexico and killed bottlenose dolphins that live in saltwater.
The Army Corps of Engineers failed to protect bottlenose dolphins and other marine life in the Mississippi Sound and Lake Borgne by opening the Bonnet Carre Spillway in 2019 without obtaining proper permits under the Marine Mammal Protection Act, according to a lawsuit.
