Kings Subbasin GSAs prepare to submit revised Groundwater Sustainability Plans by July 27, 2022

The Groundwater Sustainability Plan (GSP) is the roadmap to sustainability in MAGSA and a requirement of the 2014 California law, the Sustainable Groundwater Management Act (SGMA). SGMA required areas designated as medium- or high-priority and critically overdrafted to complete a GSP by January 31, 2020.

MAGSA, along with the other Kings Subbasin GSAs, developed and submitted its GSP and a Kings Subbasin coordination agreement to the State by the January 31, 2020 deadline.

SGMA is an iterative process and includes designated periods for GSP review and revisions. As the regulating and assisting agency under SGMA, the Department of Water Resources (DWR) had two years to evaluate the GSPs. On January 28, 2022, DWR provided notes on what changes needed to be made for the Kings Subbasin GSPs to be complete.

The Kings Subbasin GSA’s were then given until July 27, 2022 to make revisions based on DWR’s comments and resubmit their GSPs. MAGSA and the other Kings Subbasin GSAs have been diligently working together to prepare revised Plans in response to DWR’s feedback and ultimately achieve groundwater sustainability in the region by 2040.

Board approves Implementing Rules and Regulations and Proposed Fee Schedule for the McMullin Area Groundwater Sustainability Agency Groundwater Export Policy

The Board approved the Implementing Rules and Regulations and Proposed Fee Schedule for groundwater exports at the April 6, 2022 Board Meeting. The rules and regulations serve to manage, protect, and sustain groundwater supply for the benefit of local landowners within MAGSA.

The Rules and Regulations provide specific guidance to landowners on the annual permitting process and fees related to groundwater exports extracted from land within MAGSA to any location outside of the agency boundaries.

To view requirements and export fee schedule, review the adopted Implementing Rules and Regulations on here.

Landowners who own parcels located both within and without MAGSA’s boundaries are exempt from groundwater export fees but still require appropriate export permits and reporting. The Rules and Regulations exclude entirely de minimus use (domestic wells), and production of water stored and extracted from the Aquaterra Groundwater Bank project.

MAGSA’s priority continues to be the success of its landowners. Any policies and rules and regulations will continue to be for the betterment of the area by achieving groundwater sustainability through local control under SGMA.

A draft document including an economic analysis was available on MAGSA’s website for public review and comment on December 13, 2021. MAGSA adopted its Groundwater Export Policy on December 9, 2020, providing a framework for pumping groundwater within MAGSA for use outside of the agency. The recently adopted Rules and Regulations and Fee Schedule provide the specific guidelines for implementing that policy.

Newsom Executive Order requires GSAs approve new well permits, MAGSA committed to quick approvals on behalf of landowners 

In response to extreme and continued drought, Governor Newsom signed Executive Order N-7-22 on March 28, 2022. The directive outlines orders for statewide response to drought and water shortages, including a requirement that no well permits may be approved by permitting agencies until first approved by the Groundwater Sustainability Agency (GSA) managing the area where the well is proposed. Read a memorandum from MAGSA’s General Manager on Executive Order N-7-22 below:

The seven GSAs in the Kings Subbasin, including MAGSA, are working quickly with the County of Fresno to respond to the order and develop a streamlined process for well approvals to avoid permit delays for landowners. When a new permit application comes in, the County will forward the application along with a simple PDF form for the GSA to check off and sign for approval. MAGSA is committed to reviewing permit applications and signing off as quickly as possible to avoid delays for our landowners as we enter summer irrigation months.

Permits requiring GSA approval include any new wells producing greater than two acre-feet annually, and any alterations to existing wells that require a permit. Permits for domestic wells, considered “de minimus”, will not require GSA approval.

It is not expected that this process will cause delay or prohibition of new wells for MAGSA landowners. MAGSA is doing everything it can to implement the executive order in a way that causes minimal to no interruption to the landowners it serves.

If you have questions or concerns regarding Executive Order N-7-22, contact General Manager Matt Hurley at or 559-515-3339.

Kings Subbasin GSAs coordinate in response to DWR’s comments on Groundwater Sustainability Plans

The Kings Subbasin Groundwater Sustainability Agencies (GSAs), including MAGSA, are meeting to discuss and respond to the California Department of Water Resources’ (DWR) comments on the subbasin’s Groundwater Sustainability Plans (GSPs). 

As the regulating and assisting agency under the Sustainable Groundwater Management Act (SGMA), DWR had two years to evaluate the GSPs. The agency submitted its evaluation prior to the January 31, 2022 review deadline, determining the plans to be incomplete. This status was given to all San Joaquin Valley GSPs. DWR’s comments indicate they are looking for further information about the data MAGSA used to establish certain criteria in the GSP along with greater consistency among the subbasin’s GSPs. DWR’s full assessment of the Kings Subbasin GSPs can be accessed here.

The Kings Subbasin GSAs are coordinating on revisions based on DWR’s comments, and each GSA will resubmit their GSP within the mandated 180 days after receiving the comments.  Groundwater is managed locally by MAGSA through policies, programs and projects, but long-term sustainability requires the collaboration of the entire Kings Subbasin. Click here to read more about how the subbasin has already collaborated through investment in 600 acres of prime groundwater recharge land. 

ABOUT THE GSP: MAGSA’s GSP is a roadmap for how the region will avoid negative effects of groundwater overdraft and achieve sustainability by 2040. MAGSA actively sought landowner feedback during GSP development and continues to do so through the Stakeholder Committee and other channels. MAGSA is committed to securing a sustainable groundwater supply through collaboration with landowners and the implementation of innovative recharge projects. To learn more about MAGSA’s GSP, visit the Groundwater Sustainability Portal on the MAGSA website. 

MAGSA Joins GSAs Statewide Bringing Awareness to Need for Groundwater Sustainability

KERMAN, Calif. – The McMullin Area Groundwater Sustainability Agency (MAGSA) is joining GSAs statewide to bring awareness to groundwater’s importance this Groundwater Awareness Week (GWAW) from March 6-12, 2022. GWAW was established in 1999 by the National Ground Water Association and The Groundwater Foundation to promote responsible groundwater management and celebrate local groundwater efforts across the country.  

Groundwater accounts for up to 60 percent of California’s water supply during dry conditions. As we enter a third dry year, following the second driest year on record, understanding groundwater conditions, and managing groundwater has never been more crucial. Groundwater Sustainability Agencies like MAGSA have been tasked with implementing the Sustainable Groundwater Management Act (SGMA) at a local level. MAGSA is working hand in hand with landowners to make changes that will lead to long-term sustainability.  

“Bringing groundwater to sustainable levels is not a job one grower or agency can tackle alone,” says MAGSA’s General Manager, Matt Hurley. “Our landowners are paving the way for a vibrant future through their commitment to collaborative and innovative solutions.”

“Our landowners are paving the way for a vibrant future through their commitment to collaborative and innovative solutions.”

Matt Hurley, MAGSA General Manager

This year, MAGSA’s priorities are to 1) better understand groundwater conditions in the GSA through collection of accurate data, and 2) increase groundwater supply through recharge projects and education on innovative techniques to conserve and store water. To equip landowners with more specific and accurate groundwater information, MAGSA has implemented a successful well registration program and is gearing up to roll out a well metering program. MAGSA is also committed to increasing groundwater supply in the region through the McMullin On-Farm Flood Capture Expansion Project and Aquaterra Water Bank while providing educational resources teaching landowners how to implement practices like On-Farm Recharge themselves.

Through accurate data, recharge projects, education, and collaboration with MAGSA landowners and regional partners, we will secure a sustainable groundwater supply for generations to come.

Groundwater Awareness Week: Helpful Resources

Kings Subbasin Builds for Drought Resilience at Record Pace

15 basins representing 600 acres of prime groundwater recharge land with a singular goal of groundwater sustainability

Click here to view the StoryMap outlining project details, locations, and more, and to view the highlight video.

In the short span of two years, the Kings Subbasin Groundwater Sustainability Agencies have invested in 600 acres of prime groundwater recharge land. This land represents 15 dedicated basins that are constructed or in development.

Local water managers have taken the long view as they invest in infrastructure now with the goal to bring sustainability to the groundwater supply shared by all within the Kings Subbasin region.

The additional water infrastructure is anticipated to provide over 15,000 acre-feet of recharge per year on average, directly benefitting groundwater levels for communities and ag lands in the area. An acre foot equals 325,900 gallons, or enough water to cover a football field to a depth of one foot.

Since the Kings Subbasin submitted seven Groundwater Sustainability Plan Plans (GSP) in January 2020, there has been a driven effort to successfully build groundwater recharge capacity to support Kings Subbasin sustainability goals.

Full details of the Subbasin’s efforts are outlined in a StoryMap and video here.

MAGSA’s McMullin On-Farm Flood Capture Expansion Project Underway

The McMullin Area Groundwater Sustainability Agency (MAGSA) has been awarded a $10 million grant by the State Water Resources Control Board through the Prop 1 Stormwater Grant Program to expand the existing McMullin On-Farm Recharge (OFR) Project located near Helm in Fresno County.  The Project is identified in MAGSA’s Groundwater Sustainability Plan and is a key element in a vision developed by MAGSA to achieve groundwater sustainability under the Sustainable Groundwater Management Act through innovative approaches in groundwater banking and crediting.

Phase 1 was constructed in 2012-2018 and diverts 150 cubic feet per second (cfs) of flood and storm flows at the James Bypass onto approximately 5,000 acres of private farmland. Phase 2 is currently under design and when constructed will increase the diversion and recharge capacity from 150 cfs to 450 cfs and increase the potential farmland acreage for receiving flood and storm flows for OFR by about 15,000 acres.

Phase 2 utilizes agreements between various public agencies and will be operated in partnership with Raisin City Water District, which will provide matching funds through a U.S. Department of Agriculture, Natural Resource Conservation Service Regional Conservation Partnership Program grant award. Phase 2 will rely upon and promote regional collaboration in managing water resources and facilitate the setting of regional priorities and increased self-reliance.  Combined, the projects will deliver $22 million in benefits to the area and contribute substantially to the solutions required to offset the overdraft of the last century in MAGSA and the Kings Subbasin. This would certainly be a model for State and Federal cooperation.

The project represents a large-scale demonstration project of OFR for improved and more integrated groundwater and surface waters. The project is the type envisioned by the California Department of Water Resource’s FloodMAR approach, in which OFR projects are a key component in changing statewide management that ranges from local and regional water projects to re-operation of the state and federal reservoirs for an integrated surface water and groundwater storage system that can accommodate California’s variable water supply under the changing climate. 

MAGSA, through its contractor Tetra Tech, are preparing the required environmental analysis and documentation. A draft California Environmental Quality Assessment document is expected to be available for public review during the Fall of 2021. A draft National Environmental Policy Assessment document is expected to be available for public review during the Winter of 2021-22.

Groundwater in MAGSA: Annual Report Update

The McMullin Area GSA (MAGSA) together with the six other GSAs in the Kings Subbasin submitted the second Annual Report to the CA Department of Water Resources (DWR) by the April 1, 2021 deadline.  MAGSA took every opportunity in Water Year 2020 (Sept 2019 – Oct 2020) to begin work on projects that will lead to a sustainable groundwater supply for its landowners and for the region, leveraging grant funds to begin implementing key projects in its Groundwater Sustainability Plan (GSP). Although the report indicates dryer conditions put a strain on groundwater supplies across the Kings Subbasin, the ongoing efforts of MAGSA and the collective work of the Kings Subbasin GSAs will ultimately lead to long-term sustainability.

The Annual Report provides an overview of groundwater conditions in the region including groundwater extraction, surface water supply used for groundwater recharge, total water use, change in groundwater storage, and a description of progress made toward implementing the Groundwater Sustainability Plan (GSP) since the last Annual Report.

The Sustainable Groundwater Management Act (SGMA) requires Groundwater Sustainability Agencies (GSAs) to submit annual reports to the Department of Water Resources (DWR) on April 1 of every year.

Here are highlights from the Kings Subbasin’s 2020 Water Year:

Water years 2017-2019 were overall wetter than average but were preceded by an extremely dry period.  Overall, the last five years result in near average conditions, but they include an extreme dry and an extreme wet year.

Water use for Water Year 2020 consisted of 1,353,000 acre-feet of groundwater and 958,000 of surface water. Total water use for Water Year 2020 (WY 2020) equaled 2,311,000 acre-feet, with 2,011,000 acre-feet of the total used for agricultural purposes and 300,000 for urban use.

GSAs have identified different data gaps within their GSPs that they intend to fill and are still reviewing their monitoring networks.  During this water year, the GSAs have spent significant effort to gather construction information on wells through video equipment. As construction information is gathered, updates will be made through the SGMA monitoring network portal.  Work will continue into the 2021 water year to gather the remaining construction information for wells in the water level monitoring network. MAGSA’s Groundwater Monitoring Project and metering incentive program are important projects that will help to achieve this goal in the region.

The Kings Subbasin saw improvements in groundwater storage in the 2019 water year, but 2020’s reduction  illustrates the importance of continuing to coordinate with the Kings Subbasin GSAs and engage with MAGSA landowners  to implement innovative projects that will lead to a sustainable and resilient, groundwater supply  for the region.

One such project is the MAGSA Groundwater Monitoring Project funded by a $75,000 Bureau of Reclamation WaterSMART Small Scale Grant.  Under this grant, MAGSA has teamed with the McCrometer Company to install totalizing flowmeters, pressure transducers and remote telemetry units on each of the twenty-three representative indicator monitoring wells located within the MAGSA boundary. These wells are part of the basin-wide indicator monitoring network. The data collected from these wells will be remotely communicated, downloaded into a data management system, and allow for accurate and efficient logging of required SGMA reporting information. 

In addition to monitoring groundwater, MAGSA is working to recharge groundwater levels in the region. MAGSA’s  On-Farm Recharge (OFR) project is the first-of-its-kind in the nation. Leveraging $22 million in grant funds, the project involves constructing infrastructure to capture storm and flood waters and then conveying the water to farmland. The project will also build partnerships with farmers and landowners to capture surface water for groundwater recharge on those farmlands. This project, in partnership with the work carried out through Raisin City Water District’s 2018 Natural resources Conservation Services- Regional Conservation Partnership Program (NRCS-RCPP) award, will significantly offset groundwater overdraft for the entire Kings Subbasin.

Another important project that will further groundwater sustainability in the region is the Aquaterra Water Bank project. Preliminary work on a water bank project in MAGSA began in 2020 and will continue into 2021. Located between the Kings and San Joaquin rivers, MAGSA provides an ideal location for the Aquaterra Water Bank project. Water from multiple major water systems will be delivered via new and existing channels and pump stations for recharge and storage within the Aquaterra Water Bank. In drier years, MAGSA will work with project participants to schedule extraction and return water based on participants’ share of extraction capacity and available operational exchange and delivery capability. This project will improve sustainability of local groundwater supply to help the subbasin achieve its sustainability goals while increasing resiliency and flexibility for water suppliers across the State.

Finally, MAGSA is developing a metering incentive program to incentivize early placement of flow meters, pressure transducers, and remote telemetry to comply with the metering policy and accomplish reliable extraction data at the earliest possible time. To express interest in MAGSA’s meter incentive program click HERE!

We are on the road to sustainability, and we need the contribution of our incredible landowners and stakeholders to continue reaching our goals.

MAGSA awarded $10 million grant to expand innovative On-Farm Recharge project

The McMullin Area Groundwater Sustainability Agency (MAGSA) has been awarded a $10 million grant by the State Water Resources Control Board through the Prop 1 Stormwater Grant Program to expand the existing McMullin On-Farm Recharge (OFR) Project located near Helm in Fresno County.  The Project is identified in MAGSA’s Groundwater Sustainability Plan and is a key element in a vision developed by MAGSA to achieve groundwater sustainability under California’s Sustainable Groundwater Management Act (SGMA) through innovative approaches in groundwater banking and crediting.

The grant builds off previous awards for large-scale OFR implementation:  a $5M Prop 1E grant award from California Department of Water Resources to the Kings River Conservation District in 2012, and a $7M grant award through the NRCS Regional Conservation Partnership Program (RCPP) to Raisin City Water District in 2018, both requiring substantial private cost share. 

The McMullin Projects represent the first-of-its-kind OFR projects in California and nationally. The Projects are 1) constructing necessary infrastructure to capture and convey storm waters and floodwaters to vast private farm acreage and 2) implementing farm-scale infrastructure and practices in partnership with farmers and landowners to infiltrate captured storm waters and floodwaters on those farmlands.  Through this approach, the McMullin Projects are helping to reduce the ever-increasing threat of regional flood risks and, at the same time, increasing groundwater recharge. 

The first McMullin Project was designed to divert and recharge 150 cubic feet per second of storm flow and floodwater from the Kings River across 5,000 acres of farmland.  This most recently awarded Project’s goal is to more than double the Kings River diversion rate and the total acreage enlisted for recharge. 

This expanded OFR project will implement an experimental data collection program to monitor performance and further develop OFR with greater emphasis on topics such as better integration of OFR with farming practices, protecting groundwater quality, managing costs, and improving groundwater and farmer sustainability.  Information garnered from this Project is important as California begins developing the Flood-Managed Aquifer Recharge (FloodMAR) program as a critical element of California’s water future.  It is also important for all of agriculture in developing approaches to sustain water resources while staying viable. 

Support letters from MAGSA landowners were critical for this award, and all the previous awarded McMullin Projects, demonstrating continued local unified commitment towards greater sustainability.  MAGSA was one of 24 projects funded through the Prop 1 Storm Water Grant Program. The $10M award was one of two awarded at the highest level.  Sixty-seven applications were submitted, totaling $300M in grant requests. Twenty-four projects were awarded, totaling $98 million.

Ideally, the most effective Project will be conducted through a partnership with Raisin City Water District who will provide matching funds through their (Federal) 2018 NRCS-RCPP award.  Prop 1 (State) authorized $7.545 billion in general obligation bonds for water projects including surface and groundwater storage, ecosystem and watershed protection and restoration, and drinking water protection. The State Water Resources Control Board administers Prop 1 funds.  This would certainly be a model for State and Federal cooperation. 

Combined, the projects will deliver $22 Million in benefits to the area and contribute substantially to the solutions required to offset the overdraft of the last century in the GSA and within the Kings Subbasin.  Each of the individual Project(s) are supported by the continuous assistance of both Bachand and Associates and Provost and Pritchard Engineers. MAGSA’s General Manager Matt Hurley commented that “We have one of the most competent and cohesive professional, outreach and landowner collaborations on this team.  We are in truly in great hands as we develop the solutions for MAGSA’s future. We can’t wait to get this Project moving forward!”
