Opal Springs
Opal Springs is Oregon's premier artesian spring — a benchmark water asset. Producing 2,500+ GPM of pristine basalt-filtered water from a confined aquifer at 350ft depth, this perennial source has flowed continuously for over a century. Water meets all EPA primary and secondary standards with no treatment required. The 320-acre parcel includes riparian buffer zones, existing bottling infrastructure, and senior prior appropriation rights dating to 1909. This is the reference asset for the Hi3 Water Intelligence Score system.
