I am not sure about a dead zone, it is the regions prime fishing grounds for shrimp, could check the production reported from the shrimpers down there, Studies have shown that the natural removal of NOX is taking place in the "deadwater" and slow flowing creeks, twice as much as they have thought before. These are areas that people habitat by draining or covering, swamps or bogs, effectively reducing the ability to remove NOX from the area and instead running the pollution directly to the faster flowing water and yes, into the gulf. If there is a dead area, it should have shown up in the great lakes also. There is a seasonal "roll over" that has caused fish kills but I think it has happened since before Michigan being commercialized. There is a very active and profitable fishery in the great lakes and the present fear is non-native fish being brought in through ocean freighters that could cause more damage than the mother-load of chemicals that currrently reside on the bottom of our lakes! But yes, there is stuff in the water that shouldn't be there!!!! and all over the midwest, Pregnant women shouldn't eat the fish! and I'm sure this is a common warning accross most of the States. One thing to search for is dead lakes in Canada, can be sure it is not from farming, tis electrical plant output that is killing their lakes. Funny they use mostly hydro too. ???
