Idaho well logs, made useful.

Every well reported to the Idaho Department of Water Resources — how deep it went, where the water stood and what it produced — 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.

These are IDWR records

Every figure here comes from the Idaho Department of Water Resources wells 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.
