From Idaho Department of Water Resources, Water right points of diversion (active licensed and decreed rights), 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.
