8. Sustainable Yield 4

9. What is Sustainable Yield?
“Sustainable yield means the maximum quantity of water, calculated over a base period representative of long-term conditions in the basin and including any temporary surplus, that can be withdrawn annually from a groundwater supply without causing an undesirable result.”
California Water Code Section 10721 10

10. Sustainable Yield Actions
Demand-side sustainability actions:
Reduce agricultural and urban GW use to achieve sustainability
Supply-side sustainability actions:
Identify project and management actions to achieve sustainability
Composite sustainability actions:
Combination of demand-side and supply-side actions 11

11. Sustainable Yield Modeling Assumptions
Determine GW use reduction by 2040 to provide a soft transition to complete sustainability conditions

Sustainable Management 12

12. Summary: Sustainable Yield
To maintain sustainability, long-term GW use to be reduced between 2020 and 2040
Next Steps:
Supply-side sustainability actions: Identify project and management actions to achieve sustainability 13

13. Projects and Management Actions4

14. Approaches to Meeting Sustainable Yield
Allocation Approach
Basin-Wide Approach
AF/acre groundwater allocation to meet sustainable yield
Basin-wide supply projects eliminate overdraft
Groundwater allocations are assigned to GSAs based on acreage; GSAs implement additional supply projects as needed / desired
All groundwater users pay into project implementation
Basin Sustainability 15

15. Comparison of Approaches
Pros
Cons
Allocation Approach
Standardized approach
Clear cut limits on pumping
Metering needed
Pumping limitations may be significant in some areas
More GSA oversight required
Basin-Wide Approach
May be more cost-effective
Could be scalable
Well positioned for outside funding
Preserves flexibility
Projects must be economically feasible 16
