A New Era in Groundwater Management Begins

Kerman, CA – A new era in the sustainable management of groundwater in a portion of Fresno County for the next 20 years and beyond was initiated by the McMullin Area Groundwater Sustainability Agency (MAGSA) Board of Directors with the unanimous adoption of a Groundwater Sustainability Plan (GSP) at their November 6 meeting.  

“This action by the Board represents two years of focused effort by MAGSA’s Board, technical consultants, and stakeholders to develop a plan that gives our landowners the tools and flexibility they need to effectively manage their groundwater use,” stated Board Chair Don Cameron. “MAGSA has taken a critical first step to secure the future of opportunity and economic viability for the landowners in the region.”

MAGSA is the first of seven groundwater sustainability agencies in the Kings Subbasin (and one of the first in the State of California) to adopt their GSP, which must be submitted to the State for review by January 31, 2020. MAGSA’s GSP is one of the foundational elements to achieve sustainability in the King Subbasin, a critically overdrafted groundwater basin that lies within Fresno County.  

“Having the first GSP to be completed and adopted in the subbasin is a testimony to the determination of the Board and MAGSA landowners,” stated MAGSA General Manager Matt Hurley. “MAGSA has distinct challenges to overcome. It is a groundwater use only territory with a large portion of the area without water district oversight,” stated Hurley. “Being first out of the gate with a solid, informed Groundwater Sustainability Plan indicates on day one that MAGSA is up to the challenge.”

Approximately 55% of MAGSA’s 118,783 acre territory is within the service areas of Raisin City Water District and Mid-Valley Water District with 45% of MAGSA’s service area located outside of local water districts in what is referred to as the “white areas”.

MAGSA’s GSP is a roadmap for how to achieve balanced levels of groundwater supply and defines a path forward for groundwater sustainability. It describes localized groundwater conditions and identifies innovative solutions. The GSP does not propose starting off with pumping restrictions, changes to cropping patterns, land use conversion, or land fallowing. Instead, MAGSA’s top priority is to develop water supplies. Another immediate implementation action is to fill data gaps to form a more comprehensive and accurate picture of groundwater conditions. MAGSA’s Board is proposing a phased approach over 20 years to mitigate the target overdraft of 91,100 acre-feet per year, MAGSA’s allocation of the Kings Subbasin total 122,000 acre feet per year overdraft.

Starting in 2017, the MAGSA Board created a stakeholder-driven process with monthly public meetings by the ad hoc technical advisory committee to provide GSP updates and receive input from the public. This informed the development of the GSP, ultimately creating a more robust document for the localized MAGSA area. In July 2019, the Board approved opening the draft Groundwater Sustainability Plan (GSP) for a 90-day public review and comment period. First in the Kings Subbasin to release a full draft GSP, MAGSA staff and consultants allowed ample time to consider comments and make any necessary revisions to the draft prior to adoption and submittal to the State by the January 31, 2020 deadline.
