Home to catfish, crawdads, shrimp, spoonbills, and even a gator or two, Lake Peigneur was also a hub of human activity and industry, including the Diamond Crystal Salt Mines. As the lake itself narrates in this gripping blend of history, science, and real-life drama, water and salt mix all too well. On November 20, 1980, a random drill hole produced a vortex that drained the lake into the enormous caverns below—caverns created by the removal of salt—and the lake was gone.
