Huh? Why would you shut off water anyways? All replacing the anode does is make it take longer for stuff to attack the tank's lining. Similar to the idea of zinc anodes on a boat/motor.
If you close off your hot lines and your heating elements fail and stay on you get a bomb. If you close the cold feed and your tank runs out of water and is still on, that's bad too.
