Unified Water Plan for the San Joaquin Valley Project: Progress and Insights


The California Water Institute at Fresno State and the Water Blueprint for the San Joaquin Valley are leading efforts to address water management challenges in the region. Their ongoing work to develop and integrate subregional water management initiatives into a comprehensive water plan is crucial for ensuring the sustainability and resilience of the San Joaquin Valley’s water resources.


Data-driven GSP Summaries

A core aspect of the work completed so far involves meticulous data mining and normalization from Groundwater Sustainability Plans (GSPs) to create effective summaries for each subbasin. These summaries are then presented to the subbasins to confirm the adequacy and intention of the data. These presentations cover a wide range of topics, providing an in-depth overview of each basin, including historical land use, population growth estimates, the involved agencies, and the flow of information used for the analysis. This structured approach ensures that all relevant data is accurately captured and analyzed.


GSP Summaries Categories 

The GSP summaries that have been compiled focus on the following categories:

  1. Water Supply Demand
  2. Future Changes
  3. Supplemental Water Supply Objectives
  4. Historic Water Budgets
  5. Modeling of Future Conditions
  6. Recharge
  7. Flood Protection
  8. Disadvantaged Communities (DACs)
  9. Groundwater Quality
  10. Current Conveyance in the Subbasin
  11. Water Balance Projection for the Subbasin


In addition to the above a comprehensive list of proposed projects aimed at enhancing water management and sustainability are included. 


GSP Summary Presentations

The information completed has been prepared and presented to some of the GSA Managers in the Kaweah, Kings, and Delta-Mendota Subbasins, which was well-received, with feedback provided for further refinement. Additional subbasin meetings are scheduled in the coming months to continue this collaborative effort.


Additional GIS Analysis

Geographic Information System (GIS) analysis has also begun, incorporating layers of flood plains, water quality, subbasins, and Groundwater Sustainability Agencies (GSAs). This analysis enhances the understanding and planning of water resources, providing a comprehensive view of the various factors affecting water management in the San Joaquin Valley.


The work of the California Water Institute at Fresno State and the Water Blueprint for the San Joaquin Valley is pivotal in developing a unified and sustainable water plan for the region. By integrating subregional water management efforts and local projects, they are paving the way for a resilient and sustainable future for the San Joaquin Valley’s water resources.
