Unless it was fresh water it wouldn't do you any good at all, other than breed mosquitoes if you left it there. If your going to bait just use food like corn or something. Deer gravitate towards bodies of water, not something in a bucket. But I think if I am correct they get a lot of their water intake by licking it off off plants and stuff when it dews. And they probably get a certain amount from the actual vegetation they browse on.

I could be wrong on that, but I know other animals do it.
