coming out of the storm drains and just flooded the street - where are you?


I think he was off Old Jefferson. So Where 73 and 948 meet on your map and heading north up 73 would concern me. Continuing south down 73 will see this backwater effect first though.

That's concerning. So a TD user basically said that water was coming out of his storm drains, apparently in Old Jefferson, and it filled the street with water very quickly. Remember how I said we are watching the gauge at Manchac Point - the crest has not reached there yet (shown by the x). There is another point further up stream where Clay Cut Bayou flows into. Technically if backwater flooding were to occur, we should see it happen there before any backwater flooding for most of Baton Rouge along Bayou Fountain and Ward Creek happens.



Backwater flooding would be basically water flowing backwards (as indicated by the red arrow). This basically means, water flowing OUT where it is supposed to be flowing IN, and in this case, water flowing out of storm drains flooding streets would meet that definition.

So here is the gauge for this user's location:

That's a jarring rise in water levels. I would certainly say people along Clay Cut Bayou are under the gun right now. It will be a while until Manchac Point crests, but if Clay Cut is already experiencing backwater flooding at only 16-17' on the Amite, then said flooding could be extensive along Bayou Fountain.
