The oil from the ruptured well is seeping into Lake Pontchartrain, threatening another environmental area once more. The Louisana Department of Wildlife and Fisheries have issued precautionary fishing closures in parts of Lake Pontchartrain and in Lake Borgne, Lake St. Catherine, the passes and surrounding areas. The state's Department of Health also closed all oyster harvesting areas east of the Mississippi River, which includes Lake Borgne.
For whatever it's worth, the oil spill can now be seen from space. (photo below)
