The state of Maine keeps a log of every well ever drilled. We read all 95,271 of them.
Maine well logs, made useful.
Every well card the Maine Geological Survey holds — how deep it went, what it yielded and who drilled it — brought together around one address, instead of one record at a time.

What you can answer here
- How deep will my well need to be? Median and range of actual drilled depths near you — not national averages.
- What will it cost? Local median depth × published per-foot rates, with the math shown.
- Will it produce enough water? Yields from pump tests on nearby wells.
- Who drills around here? The drillers who actually filed recent well logs in your county.
Every figure here comes from the Maine Geological Survey well database — the state's official well-log repository. We index those same records by location so you can start from an address, and every well links back to its original filed log.
