Montana water data
Well depth, groundwater and water rights, place by place.
The state of Montana keeps a log of every well drilled, a register of every water right, and a record of every reported petroleum release. We read all of it and compute the same statistics for every county, community and ZIP code: how deep wells go, where the water table sits, what wells produce, which rights are on file and which environmental sites are nearby.
Updated November 2026 · 280,969 wells statewide · 56 counties · 180 communities · 329 ZIP codes
Area statistics are context. For the water picture around one parcel, run a property water report.
