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 | 15 | 96 ft | 88–160 ft |
| Irrigation | 308 | 190 ft | 42–220 ft |
| Public supply | 6 | 220 ft | 130–230 ft |
| All water-supply (headline figure) | 330 | 180 ft | 42–220 ft |

About these numbers
- Sources: St. Johns River Water Management District (454 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: the source layer for this area publishes no construction or permit date, so we can’t say how recent these wells are.
- Approximate locations: 196 of 454 records (43%) 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.
Questions
- How deep are wells in St. Augustine?
- All water-supply wells in St. Augustine have a median reported depth of 180 ft. The middle half are between 42 ft and 220 ft, based on 330 SJRWMD records.
- Will a new well at my property in St. Augustine be this deep?
- Not necessarily. These are depths other wells were permitted or built to. Depth depends on the aquifer, water quality, use and local rules. A Florida-licensed water well contractor and your water management district can tell you what a new well at your property needs.
- Where does this data come from?
- From public well-construction records published by the St. Johns River Water Management District. Each well in the lookup links to its original agency record.
