Depth by well type

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.

Will a new well at my property in St. Augustine be this deep?

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.
