Airborne Geophysical Surveys over Big Valley, Scotts Valley, & Northshore in November

LAKE COUNTY, Calif (October 29, 2021) – Airborne geophysical surveys will be conducted throughout Lake County in the month of November. They are currently expected to start November 8-11. These surveys will help improve understanding of our communities’ groundwater resources, and support local sustainable groundwater management efforts.
During these geophysical surveys, also referred to as airborne electromagnetic (AEM) geophysical surveys, data is collected via a large hoop towed beneath a helicopter (shown left).
Surveys will only be conducted during daylight hours. The helicopter will not fly over businesses, homes and 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.
