An aulacogen is the failed arm of continental rifting...
To the West, forming Atlantic left aulacogens at what's now the Amazon and Mississippi...
If Mississippi had opened to eg Red Sea size before 'failing' at New Madrid, leaving a significant seaway, what are the implications ??
I'm assuming that there's enough scour & tidal resonance to prevent 'inland' silting ...
I would expect the Great Lakes to empty South via Chicago River, perhaps with Spring Thaw floods spilling via Niagra...
I suspect the weather would be 'livelier' on Plains due 'lake effect'.
Thoughts ??
