About these numbers
- Sources: Southwest Florida Water Management District (1,635 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: 411 of 1,635 records (25%) 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.
