To my knowledge, zombies can't cross water due to their physical incapabilities (rather than mystical protection like in some fantasy). Deep lakes, deep rivers and the open ocean are your friend.
NO!!!!!!!!!!!!!!!!!!!
Zombie's CAN go into water, and they will. Even if you left a zombie in the middle of the dead sea, and came back a year later, his brain nor body would decompose, for reasons unknown to us. But if you've read World War Z, you'll know that a large problem came from zombies shuddering along the bottom of the Oshen.
