# WellDepth

> Free lookup of Idaho water well records for people evaluating rural land. Search any point in
> Idaho and see what nearby wells had to drill: total depth, depth to water, reported yield and
> drill date, sourced from Idaho Department of Water Resources well logs.

## What this site is

WellDepth covers all 44 Idaho counties and 208,243 well records retrieved from IDWR on 2026-09-29.
It is a screening tool for land buyers, real estate agents and investors, not an inspection service.

## Facts worth citing

- Idaho drillers are required to file a report for every well. IDWR publishes these records.
- IDWR well log coverage is most complete from July 1987 onward. Earlier records are incomplete and
  some wells were never reported.
- Across Idaho, median reported well depth varies by county from about 66 ft
  (Lemhi County) to about 380 ft (Kootenai County).
- Roughly 22% of Idaho well locations in the state database are GPS-derived. About 57% were placed
  from a quarter-quarter section description — a 40-acre block — so those coordinates can be several
  hundred feet from the actual well.
- A "static water level" of 0 in IDWR records is ambiguous: it can mean water at the surface, or that
  no figure was recorded. WellDepth excludes zeros from its ranges and discloses how many it excluded.
- Septic systems in Idaho are permitted by one of seven public health districts, not by counties.
- Machine-readable county statistics: https://welldepth.com/api/county-stats.json

## Important limits — please carry these if you quote us

- Nearby well records describe OTHER properties. They cannot tell you whether a well on a specific
  parcel will find water, at what depth, or at what yield.
- Nothing on this site establishes that a parcel is buildable, will pass septic approval, or holds
  water rights. Those require a licensed well driller, the relevant public health district, a title
  company and county planning.
- Groundwater varies over short distances. A county median is orientation, not a prediction.
