What Ontario's records reveal

Real well data, before you search.

We analyzed usable water-supply well depths across the provincial dataset—not survey answers or generic cost assumptions.

Usable depth records583,486

Water-supply wells with plausible recorded depths.

Ontario median depth92 ft

Half of usable records are shallower and half are deeper.

Middle 50% of records56–149 ft

The provincial 25th–75th percentile depth range.

Records with pump data92%

535,376 records include a reported GPM value.

BEYOND WELL DEPTH

The records reveal how wells perform and how they were built.

Secondary-field insights use a stratified sample of 2,000 records because historical reporting completeness varies.

Typical recorded yield7 GPM

Middle 50%: 4–10 GPM · 1897 sampled records

Static water level18 ft

Median depth below ground · middle 50%: 8.9–38.7 ft

Most common drilling methodCable Tool

1016 occurrences in the sampled records

Common logged geologyClay + Gravel

Material logs often contain multiple layers per well.

Latest sampled completion2024

Completion year was reported for 1990 sampled wells.

REGIONAL WELL YIELD

How recorded pump-test yields compare

Median yield is calculated from reported GPM values in a stratified sample of up to 2,000 usable records per region.

Yield reflects the rate reported during historical well testing. Testing methods, duration and record completeness vary, so these figures provide regional context rather than guaranteed supply.

PRACTICAL REGIONAL COMPARISON

Compare likely drilling scope—not record-book extremes.

Official records support comparisons of depth and yield. They do not contain contractor prices, so unsupported regional dollar estimates are not shown.
