Alaska well logs, made useful.
Every well log Alaska DNR holds — how deep it went, who drilled it and what it produced — brought together around one location, instead of one log 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.
These are Alaska DNR records
Every figure here comes from the Alaska DNR well log tracking system (WELTS) — 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.
