Spring in Allenspark has awesome water. Most call it free however there is a donation box at the spring. It has a suggested per gallon donation amount. We went with that.
I do recall a spigot but the camp host was hooked up to it. We did not rely on water there - opted to fill prior to arrival. Given how tight it can be in the campground, I would recommend filling outside of Olive Ridge so you can head right to your spot.
