Whether a new home can legally get its own water here — the sub-state groundwater regime, from Washington’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.
RCW 90.44.050 exempts up to 5,000 gpd for domestic use, but the 2018 Streamflow Restoration Act caps NEW permit-exempt domestic wells at 3,000 gpd/connection in some basins and 950 gpd (350 gpd indoor in drought) in others, and new post-2020 wells in the adjudicating Nooksack basin are limited to ~500 gpd indoor.
Limit: 5,000 gpd base (RCW 90.44.050); capped to 3,000 or 950 gpd/connection in streamflow-restoration basins; ~500 gpd indoor for new Nooksack wells
Washington Dept of Ecology — Groundwater permit exemption ↗New permit-exempt domestic wells capped at a maximum annual-average 950 gpd per connection, curtailable to 350 gpd indoor-only during a declared drought emergency.
Washington Legislature — RCW 90.94.030 ↗WAC 173-505 sets minimum instream flows; post-rule groundwater withdrawals in hydraulic continuity are junior and subject to interruption.
WA Dept of Ecology ↗Hybrid state (appropriation + riparian). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Washington state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
