About this listing
Plymouth Park is listed in John Day Lock and Dam, Lake Umatilla. This record is sourced from federal recreation data through Campsite Atlas. Details can change; use the official source before traveling.
Data interpretation: campground-level amenity flags mean the amenity is reported somewhere in the campground—not at every site. “Not verified” is intentionally different from “No.”
