You know, I've never had a problem with them chewing on inappropriate things at night. Lucky I guess? I know Gunnar liked to wake up and chew on a toy(make sure it's a soft, quiet chewy) for 5 minutes and would fall back asleep. Bosco would sleep, no problem but he had a great play buddy to tire him out.
I've found for myself that I'm just not a good crate trainer. You have to get the puppy really used to it slowly and make it fun but it's hard when the first night you bring your pup home he has to go in a crate(when he's so used to sleeping with his litter mates, no less) when you just haven't had the time to introduce it properly. My bedroom was pretty puppy proof and I never really get too attached to personal items so I took a chance of having chewed nightstands.
Instead of putting the water in her crate maybe just let her have access to water when you take her out for her bathroom breaks. She doesn't need much, just a few sips.
Good luck! You'll find what works.
