Well Information Application

Content

Information related to wells in Santa Clara County can be accessed using Valley Water’s Well online, interactive, Information App.   https://gis.valleywater.org/wellinfo/

Well Information online map tool

When using the Well Information Application, please note that:

  • Well locations depicted in the system are approximate but should show the wells’ approximate locations with respect to other features, such as property boundaries.  The wells shown were not surveyed by Valley Water and should not be thought of as survey-grade location data.
     
  • There may be other wells that are not shown on the map or contained in the well attribute data.  Valley Water’s well data and associated database and mapping application only contain location and attribute data for wells that we permitted and/or registered.  Because Valley Water did not initiate our well registration program until the 1960s (for the North County) and the 1980s (for the South County) and did not initiate our well permitting program until the mid-1970s, it is always possible that wells were abandoned and buried without ever being known to Valley Water and/or added to our data set.
     
  • Like the well location data, well attribute data may not be complete and/or accurate for all wells.  Well data acquisition was completed from the period between the mid-1960s through present, and some well data may be inaccurate or missing.

For more accurate well attribute data for each well, we recommend that system users contact the State of California’s Department of Water Resources to request a “Well Completion Report” for each of the wells of interest to them.  The Department of Water Resources is the owner of record for Well Completion Reports.
