Before you go

Trailer dump: USD 5 per use with a Discover Pass; waived if already paid for camping in the same park. Operator lists Trailer Dump and a $5 per-use fee. Coordinates identify the park, not a surveyed dump inlet. Follow onsite signs. The park says winter water is only available at the dump station; this does not establish potable-water filling availability.

A source check is a desk review, not a site inspection. Availability can change. Water marked unknown must not be assumed safe to drink.
