In the late September to early November timeframe, the flow in the river was insufficient to keep the saltwater out. It appears that even last week the saltwater wedge had pushed 63 miles up river. It seems like the river is beginning to win this month. I haven't seen any articles more recent than mid-October so maybe the problem has abated for this year. |
Not about river levels?
Then please explain this post that started this offshoot of the thread:
"The Mississippi River is at the lowest levels recorded. In July, The Army Corp of Engineers had to quickly devise a means to stop the salt water intrusion from the Gulf that could destroy the river."
