The meetings and technical discussions focused on the Periodic Evaluation and amendment of the Groundwater Sustainability Plan. Key topics included updates to the monitoring network, specifically the installation of new wells and stream gages to fill data gaps, and revisions to sustainable management criteria including groundwater level measurable objectives and interim milestones. The committee reviewed a proposed fee study, discussed potential impacts on domestic and other users, and addressed recommended corrective actions from the Department of Water Resources related to contamination sites, interconnected surface waters, and undesirable results definitions.

The Board meeting focused on the consideration and adoption of the Fiscal Year 2026/27 Annual Operations Budget, fully funded by SGMA Regulatory Fees. A public hearing was held regarding the Sustainable Groundwater Management Act fee, including a staff presentation on the final fee study report. The Board considered and adopted several resolutions related to setting the new fee structure, the fee study report, and the certification of legal processes for placement on the secured tax roll. Additionally, reports on the program manager update, well permits, and tribal engagement were reviewed.

This document is an amended Groundwater Sustainability Plan for the Wyandotte Creek Subbasin, designed to achieve and maintain sustainable groundwater management by 2042. It addresses the Department of Water Resources' Recommended Corrective Actions and identified data gaps from the initial 2022 GSP. The plan evaluates six key sustainability indicators: groundwater levels, groundwater storage, groundwater quality, land subsidence, depletion of interconnected streams, and seawater intrusion. It updates Sustainable Management Criteria and monitoring networks to ensure an adequate supply of groundwater for rural areas, communities, agriculture, and environmental needs.
