Aims to enhance the understanding of the Vina subbasin’s conditions by installing monitoring sites and equipment, focusing on domestic wells and implementing a Community Monitoring Program, alongside preparing the five-year GSP Periodic Evaluation and engaging with the public through various outreach efforts. 

 Consultant: Larry Walker Associates

Project Partner: Butte County Water and Resource Conservation

Total Project Budget: $1,070,000

Project Outcomes

  • Expanded Understanding of Basin Conditions: The installation of monitoring sites and equipment aims to address data gaps in the Vina subbasin, enhancing the understanding of hydrogeology and hydrology. This will support updates to the GSP and ensure effective management of the subbasin.
  • Improved Understanding of Domestic Wells: By reviewing the domestic wells and establishing a Community Monitoring Program with dry well tracking, the project will provide more insights into the condition of these wells.
  • Periodic GSP Evaluation: The project includes preparation for the five-year GSP evaluation, addressing the corrective actions recommended by the Department of Water Resources (DWR).
  • Enhanced Stakeholder and Public Engagement: Regular meetings, workshops, and outreach activities will inform the public and stakeholders about the project's progress and encourage participation.
  • Domestic Well Monitoring and Community Program: A key outcome is the creation of a monitoring program for domestic wells, equipping volunteer wells with monitoring devices to track water levels and enhancing the data management system for well data.
