Top 3 Key Takeaways

1. Groundwater Model Enhancement Plan Advanced for Task Order Development

The TAC received a comprehensive presentation on proposed updates to the basin's groundwater model, which has not been significantly enhanced since 2015. The enhancement will update the model to version 1.5, incorporate current land use and evapotranspiration data, refine boundary conditions, and improve stream network representation. This proposed $129,000 update (budgeted as Optional Task 9) is critical because the model will be used to demonstrate to the Department of Water Resources (DWR) that ongoing projects are achieving the sustainability goals promised in the Groundwater Sustainability Plan (GSP). The committees agreed to move forward with preparation of a detailed task order, which will be formally considered for approval in January 2026, with completion targeted for July 2026 if authorized.
