Depth by well type
Household wells are the headline because that’s what most people planning a well need. Irrigation wells are often much shallower.
| Well type | Wells | Median | Middle half |
|---|---|---|---|
| Household | 4 | — | too few |
| Irrigation | 163 | 140 ft | 24–160 ft |
| All water-supply (headline figure) | 167 | 140 ft | 24–160 ft |

About these numbers
- Sources: Southwest Florida Water Management District (179 records). Records were fetched October 25, 2026.
- What’s counted: wells with a reported depth whose use is household, irrigation, public supply or agricultural. Monitoring wells, injection wells, plugged wells and permits that were never drilled are left out. Methodology.
- Dates: SWFWMD permits issued 1979–2026.
- Approximate locations: 48 of 179 records (27%) share their exact map point with at least four other records, so they’re probably placed at a section, subdivision or parcel-group center rather than at the well. That matters for “nearest well” distances, less for area figures like these.
- Not a guarantee: a record shows how deep one well was permitted or built. It doesn’t predict yield, water quality or what your well will need.
