An Aug. 30, 2012 photo shows a nearly submerged mailbox and cattle stranded by floodwaters after Hurricane Isaac in Plaquemines Parish, La. Hurricane Isaac turned some of the best ranch land in Louisiana into a miles-long pond of blackish and foul-smelling floodwaters. Snakes, birds and a lot of the livestock raised here by a handful of ranching families drowned in Isaac's storm surge, which overwhelmed the weak levees protecting this farm country south of New Orleans.
