The water is not coming from the river but the lake.
Its a real big lake with a couple hundreds foot breaches.
This is not rocket science - even the russians mangaed to bury Chernobyl in millions of tons of concrete and lead in short order.

Someone famous said something like, "water is an irresistible force." One can not just "plug" problems like this. As you point out, plugging buys you nil when it continues to flow over the entire bank.
And, not spoken about yet, time is the enemy of levees, as sodden foundations weaken over time.
