I was thinking just the opposite, no pass to keep it washed out and away from the Gulf side. Like it washes out of the bay and then settles back down stream. Navarre is as far from a pass as I've ever fished.
A pass in Navarre I think would definitely help with water movement. Imagine how nice it could make the inshore water from Pensacola to Destin! Even places like Quietwater beach would benefit from better water quality. Too bad there are too many old hat obstacles in the Navarre area to ever allow it to happen.
