Almost all of the state parks we've stayed at across the country have potable water at the dump station, separated by some distance from the spigot that you use to rinse your stinky slinky. Always clearly marked - just make sure you pay attention! Spigots in the campground may or may not be close enough to reach depending on how much hose you carry - we bring a 6 gallon plastic jerrycan if needed for a mid-stay refill.
Good point about the water not being turned on yet, although if the CG is open there should be a frost proof bib somewhere, maybe by the office when you check in. Phone first.

I looked at the campground map and they do have water symbols on it. It is a PA state campground. Colonel Denning state park. Looks like there is a water station across from my camp site. I still might fill up from home. I am not that far away so the extra weight is not that big of a deal. Thanks for all the input.
