Board reviewed groundwater monitoring and minimum thresholds, directing staff to prepare comparative analyses of 2022 versus 2025 data using consistent methodology and a matrix of DWR corrective actions. The board also discussed an interconnected surface water monitoring network and a domestic well mitigation framework, asking staff to research neighboring approaches and bring back options.
The committee discussed two options for recalculating groundwater minimum thresholds and agreed staff should analyze both before any changes, with agricultural members stressing data-driven justification. A possible domestic well mitigation program drew questions on scope, funding, and liability. Public comment highlighted transfer proposals totaling about 467,000 acre-feet per year. Staff will return in spring 2026 with MT calculations.
The board approved moving forward with a comprehensive domestic well risk assessment using an updated inventory of over 4,100 wells to identify those at risk from declining groundwater levels. New modeling revealed groundwater contributes over 100,000 acre-feet annually to the Sacramento River, with the river gaining water from groundwater consistently. A fee appeals process was established allowing property owners to contest fee classifications within 45 days, though fees must be paid...
The committee approved moving forward with a domestic well risk assessment using an updated inventory of over 4,000 wells, despite incomplete location data for half the wells. Members criticized groundwater modeling scenarios that showed drought resilience, arguing they were misleading since they unrealistically assume no increased water use during extended droughts. Staff identified 32 existing shallow wells for interconnected surface water monitoring, significantly expanding from the...
The board rejected both candidates for a vacant stakeholder position amid controversy over agricultural groups seeking influence in a non-agricultural seat. Domestic well advocates pushed back, claiming they already pay 57% of GSA fees while accounting for only 10% of pumping. The GSA must submit its first Periodic Evaluation by January 2027, with significant amendments expected to monitoring networks, sustainable management criteria, and interconnected surface water thresholds.
