Thanks for the clarification.

This issue comes up every now and then on the St. Johns River here in Florida when it floods. During high water, you can float over fences. It is my understanding that while the water is high, you can be in a boat anywhere there is water. If you get out of the boat on private property, you are trespassing.

I agree, flooding doesn't change property lines in regard to trespassing once the water level returns to normal. I also believe as long as you are in a boat over someone's flooded property, you should be able to fish. Wade fishing on private property is another matter...
