Airborne Electromagnetic (AEM) Geophysical Survey

Tuesday, Nov 23, 2021

The District has received notification that the California Department of Water Resources (DWR) will be conducting airborne electromagnetic (AEM) geophysical surveys within portions of Kern, Tulare, and Kings counties over a three-to-four week period starting in mid-November 2021.

 

The surveys are being conducted to improve the understanding of groundwater resources and support the local and state goal of improved groundwater management and the implementation of the Sustainable Groundwater Management Act (SGMA). The surveys are funded through voter approved Proposition 68 and there is no additional cost to locals. DWR’s video provides more information about the surveys: https://www.youtube.com/watch?v=HMSZdzz0rUE&t.

 

AEM data are collected from a large hoop towed beneath a helicopter. The method is safe, and surveys have already been conducted in several locations throughout California. Surveys will only be conducted during daylight hours and the helicopter will not fly over business, homes, other inhabitable structures, or confined animal feeding operations. The helicopter operator follows all established Federal Aviation Administration rules and regulations, and their highest priority is public safety.

 

For more information about the surveys, visit DWR's AEM project website, www.water.ca.gov/programs/SGMA/AEM. For questions, please email AEM@water.ca.gov.

 

NOTE: The survey start date and the flight period provided may be extended or delayed by several weeks due to weather, wildfires, or equipment issues. Please check the AEM Survey Schedule webpage for up-to-date information on flight days: https://gis.water.ca.gov/app/AEM-schedule.
