There are streams off of some trails. They dry up in the summer. Best to bring it with you or stop by the bathrooms/water fountains by the parking lot.
I didn't see any, nor do I generally trust water while out and about (giardia is no fun). I brought a small bowl and filled it from my own water.
My dog and I came across one stream, it smelled funny and she turned her nose up at it. I'd recommend bringing your own water for your dog.
None, bring some with you
