Top 3 Key Takeaways

1. Groundwater Dependent Ecosystems (GDEs) May Not Require Sustainable Management Criteria

Field surveys and remote sensing analysis revealed that most GDEs in the White Wolf Subbasin (approximately 870 acres south of the Springs Fault) are influenced by precipitation rather than groundwater pumping in the principal aquifer. The vegetation health responds rapidly to rainfall events like Hurricane Hillary, and these areas appear hydrologically separated from the main irrigation pumping zone. The GSA is exploring options for adjusting sustainable management criteria for these GDEs, which could include removing SMCs or establishing a separate management area, and plans to coordinate with the Department of Water Resources on any proposed approach before finalizing the periodic evaluation.
