About these numbers
- Sources: St. Johns River Water Management District (53 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.
- 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.
