We list a dump station only after checking it on the operator's own page: a state DOT, park agency, city, or business. Each listing links that source and shows the date we checked. If two official pages disagree or we can't confirm a station, we leave it out. We don't copy crowdsourced lists. Status changes fast, so call ahead.
Listings: 17 WA, 6 OR, 14 ID, all checked 2026-10-22.
