Is there a place to get in the water in the park if your camping? Creek, swimming hole, etc?

Theres a waterfall though I havent actually done the trail to it yet, so not sure about getting the water anywhere.

Nope..pray for rain

No

Creeks are there along with a fountain and bathrooms with water where they have the fall festival. The bathrooms are adjacent to the playground swings.

There is no "lazy river" in this area. The upper elevation is pretty much drinking, meal, etc type.

There are a bunch of springs, most are pretty well marked.
