What is a Groundwater Sustainability Plan (GSP)? 

The GSP is a roadmap for how a basin will avoid the adverse effects of overdraft and achieve balanced levels of groundwater to reach sustainability.

The GSP includes a physical description of a groundwater management area including current and historical groundwater conditions, a water budget, groundwater management criteria, a monitoring program, and projects and measurable objectives to become sustainable by 2040.

The California State law, Sustainable Groundwater Management Act (SGMA), requires the James GSA to develop and submit a GSP by January 2020.

Why did the James GSA develop a GSP? 

The Groundwater Sustainability Plan (GSP) is a requirement of the 2014 Sustainable Groundwater Management Act (SGMA).

The State law requires all high- and medium-priority basin GSAs (Groundwater Sustainability Agencies) develop and implement a GSP. Basins designated as medium- or high-priority and critically overdrafted are required to complete a GSP by January 31, 2020. SGMA defines a basin as critically overdrafted “when continuation of present water management practices would probably result in significant adverse overdraft-related environmental, social, or economic impacts.”

James GSA is one of seven GSAs within the Kings Subbasin implementing a GSP. The Kings Subbasin GSAs submitted their GSPs and a formal coordination agreement to the California Department of Water Resources on January 28, 2020 for initial review.
