NEW Landowner Well Registration Program

The North Fork Kings GSA has launched a well registration program. Landowners’ prompt action in the program is important to keep local control of groundwater management. The well registration program is most immediately tied to a State-required groundwater study on the confined aquifer. Over the next several months, the North Fork Kings GSA is conducting this study to better understand land subsidence and groundwater flows. Landowner participation is an important part of completing the study by fall 2024.

Wells can be registered online via a new web-based platform called Watermark.

To participate in this initiative, landowners must activate their Watermark account and register wells using a short form within Watermark.

📪 LANDOWNERS! Letters were mailed on January 31st containing your unique verification codes. These codes are necessary to add your parcels and complete the registration process.

Your well registration helps keep groundwater management local.
