From Oregon Water Resources Department, Water rights points of diversion (OWRD water rights query service), fetched October 12, 2026. The state's own record is the authority: amounts, owners and status here can lag behind it, and a mapped point of diversion says nothing about which parcel the right serves. This page is not legal advice.
