It would greatly depend on the part of Baton Rouge.
If it broke at downtown, north Baton Rouge would have some issues but it’s still gonna flow towards the southern part.
If it broke more around gardere, all of that area and all of those neighborhoods on Nicholson and Burbank would be fricked
Basically on the east bank of the river the levee starts around north st. (not to be confused with North Blvd.). There really isnt a man made levee north of that, The natural bluff along the river in baton rouge starts to get further and further away from the river south of north st.

If it broke downtown, then it would still primarily flow South along Nicholson, flood the lower portion of LSU including the PMAC and Tiger Stadium, and then keep on going toward Brightside and then eventually to Bayou Manchac -> Amite River -> Lake Maurepas.
North BR is generally higher ground.

Use the loop to evacuate.

you're right, the water would never go to the quad, too many better floods there before it, could never live up to them

It will only hit gradere and north BR. Because weather events and natural disasters are racist

Not so fast my friend.
Water would only come up to sea level if the MS River got diverted. Thats a hell of a lot of dredging and digging to make up that difference at the BR port.
Also the petro chemical corridor would be totally fricked as they lose their fresh water intakes.

I'm genuinely curious what happens if the forecast crest of 43' in BR occurs (which we have every reason to believe it will and this is by no means record levels) and then a 4' section of levee washes away sometime over night due to the increased pressure on the levee at a time when it's saturated from heavy rain since November. Where would all that water spread out to? It would eventually (within a couple days I'm sure) flow into the Comite and Amite Rivers, flooding Livingston, Ascension and St. James parishes pretty badly as well.
Just to put it into perspective: The 2016 flood was caused by about 7.1 trillion gallons of water dropped in 3 days.
The Mississippi River flows about 700,000 cubic feet per second at max, which is about 5.25 million gallons per second. At that rate, it would take 1,350,000 seconds to put the same amount of water heading toward the Amite and Comite. That would take 15.5 days to equal the same amount of water, and that's if the Mississippi goes completely dry downstream of BR because it's busy monkeyfricking us.
The short answer is I have no fricking clue.

They'd figure out some way to divert enough water to the Mississippi River's current channel to keep it navigable.

That 7.1 trillion gallons of water dropped in 3 days in 2016 was across an area from Hammond to Lafayette southward to Houma. That's not 7.1 trillion gallons of water all going through the Amite and Comite during the 2016 flood. If the Mississippi levee breaks in the BR area, you'd see 2.2 trillion gallons of water flowing only through EBR, Livingston, and Ascension parishes after 5 days. Theoretically it would take much longer than 5 days to plug up the levee.

Everything west of highland rd and south of LSU would be fricked

Negatory Mississippi hit 1.5 million cfs in 2011. Its over 1 million cfs rn

Anyone here with actual real knowledge of this type of scenario? What would that look like?
I don't know, but i I have a feeling property values in the neighborhoods east of highland road would increase quite a bit.

Probably do about one billion dollars in improvements

highland road is the natural levee that ends the flood plain so up that area where the elevation changes

I know we wouldn't have that new downtown library anymore
