Air draft on the Mississippi?

[Jdege]

I have a sailboat on Lake Pepin, and I'm planning on getting it down to the Gulf.

One of my options is to head down the river.

Now I know the Great Loopers have to drop their masts to get through Chicago, and I vaguely remember there are air draft limitations on the NY canals. But are there any others? What's the minimum air draft of the Mississippi from Red Wing south?

FWIW: The NOAA Air Gap system is a tool that measures the vertical clearance between a defined reference point under a bridge and the surface of the water below.
