Five Oregon State Parks sites in Eastern Oregon list an RV dump station on their own park pages. We checked each page on 2026-10-27. Late October is when most of them shut for the season, so the status column matters more than usual here. Goose Lake and Farewell Bend post the standard state park terms: $10 per use, paid by QR code at the station, no camping reservation needed, and registered campers pay once per stay (fee details). The other three pages don't post a fee, so we don't guess one.

Winter tip: Wallowa Lake is the only one of the five whose campground stays open all winter with the dump station listed alongside it, and its water is off at most sites. Bring your own rinse water and see winter RV dumping. Call the park before a long detour; numbers are on each park page.
