Pilot Study Goals

The goal of the pilot study is to acquire survey data to help us make better informed decisions about managing our groundwater resources. Survey data is collected using aerial groundwater mapping technology to characterize and map out the layers and extent of clays, silts, sands, and gravels to a depth of approximately 1000 to 1400 feet below the ground surface. Existing well data will be used to verify the survey results. This pilot study will enhance Sustainable Management Groundwater Act (SGMA) related groundwater modeling and provide a better picture of our groundwater system.
