Groundwater Allocation

The MSGSA is currently developing a Groundwater Allocation Rule that will be used by the MSGSA to administer and govern the allocation of native groundwater available to the MSGSA for agricultural lands within the MSGSA’s boundary.  The implementation of the to-be-adopted Rule will enable the MSGSA to reduce the consumptive use of native groundwater to meet the objectives of the Merced Subbasin Groundwater Sustainability Plan, as adopted by the MSGSA on July 19, 2022, and approved by the California Department of Water Resources on August 4, 2023. 

The MSGSA released a framework that provides an overview of the Groundwater Allocation Rule’s scope and contents on February 8, 2024, and anticipates releasing a draft version of the Rule to the public following its June 2024 Board meeting, with anticipated adoption at its July 2024 Board meeting.  Additionally, the MSGSA has developed a Groundwater Accounting Platform that provides landowners with the ability to monitor groundwater use that will become more limited through the to-be-adopted Rule governing groundwater allocation.  From now through December 31, 2025, the platform will be limited to helping landowners view and track water use on their lands.  Beginning January 1, 2026, the MSGSA will begin monitoring water use against the groundwater pumping allocation set forth in the to-be-adopted allocation Rule.
