Notice the car on the bridge? Supose it is moving?

I assume the breech is above the bridge in the picture where the white top of the levee is missing?

Doesn't look like a 3000 pound sandbag is going to do anything to slow that gash down unfortunately.

From the CNN weatherguy's explanation earlier, I'm gathering that the main break is the one in this edited slice from the big link above, Lake P being in the direction of the bottom of the picture:

But there appears to be another, smaller (for the moment) breach on the other side of the canal.
Perhaps a result of hydrologic forces in that direction from the original break ?
