After decades of investment in water supply infrastructure and technical studies, we now have the clearest and most grounded understanding of how the Salinas Valley’s groundwater system actually functions—and what it will take to manage it sustainably.
The 2025 Historical Benefits Analysis (HBA) represents a major step forward.
Built on the Past, Ready for the Future
Earlier efforts helped define critical water management zones, reveal patterns of overdraft, and underscore the urgency of addressing seawater intrusion. They laid the foundation for the reservoir projects, river diversion facilities, and agricultural delivery systems that have supported the valley’s productivity.
But the 2025 HBA goes further. It connects project operations with groundwater impacts in a way that is spatially detailed, technically robust, and grounded in real system behavior. This isn’t just a review of what we hoped would happen. It’s a detailed account of what actually happened.

What Makes the 2025 HBA Different
This analysis provides a more accurate, more accountable, and more transparent framework for evaluating benefits across the basin.
- It’s spatially precise. Instead of broad zones, the 2025 HBA breaks the valley into 13 distinct areas—so we can see what’s working where, and who’s benefiting from what.
- It’s rooted in actual groundwater response. It uses a fully calibrated model to show how heads changed, how much pumping was reduced, and where recharge was effectively stored.
- It’s balanced. It highlights successes where recharge strategies are working, but it doesn’t shy away from identifying ongoing challenges.
Why It Matters for Landowners
This HBA offers the kind of clarity that’s essential for future decisions—whether those involve rate structures, SGMA project prioritization, cost-sharing discussions, or protecting productive agricultural land.
The findings are transparent, the methodology is sound, and the analysis stands ready to support smart water policy for decades to come.
The Bottom Line
The 2025 HBA gives us more than numbers. It gives us insight: insight into where our investments have worked, where further attention is needed, and how to make smarter, more equitable decisions moving forward.
This is not just another study. It’s a smarter way forward for the Salinas Valley.
