Snakes and alligators don't stay still, they need more than water to survive. If an enclosure was built to keep them in place, it would keep out all the 'prey' (though I don't know what suitable prey would be wandering about in significant numbers in the desert) and the immigrants. So, this is ridiculous. There would need to be game wardens all along the border wall to feed the things during times when immigrants are scarce.
That leaves the electricity, which won't happen either.
