Whether a new home can legally get its own water here — the sub-state groundwater regime, from Oregon’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
Single or group domestic groundwater use up to 15,000 gpd is exempt from permitting, but the exemption can be limited inside designated Critical Groundwater Areas.
Limit: 15,000 gpd domestic (plus stockwater and ≤0.5 acre lawn/garden) under ORS 537.545
Oregon Water Resources Department — Exempt Water Uses ↗Declining basalt/gravel aquifers designated critical; new groundwater appropriations are closed/heavily restricted and some exempt uses may be curtailed.
Oregon Water Resources Department — Critical Groundwater Areas ↗Classified 2017 over basin-fill and Columbia River Basalt (480 sq mi); 'exempt uses only' — new non-exempt groundwater appropriations closed. Exempt domestic wells allowed.
