New Report Addresses Findings That Most California Groundwater Sustainability Plans Fail to Protect Vulnerable Communities and the Environment

August 10, 2023

A new report, authored by experts from organizations including The Nature Conservancy, the Union of Concerned Scientists, Audubon California, and Clean Water Action, provides a set of recommendations on how California’s Sustainable Groundwater Management Act can better protect vulnerable communities and the environment. The recommendations are based on findings from a study published this week in Nature Communications, which found that the majority of local groundwater plans developed under California’s Sustainable Groundwater Management Act (SGMA) overlook the state’s most vulnerable groundwater users.

More than 100 groundwater sustainability plans submitted to the State of California and required under SGMA in 2020 and 2022 were rigorously reviewed to assess the degree to which each plan integrates diverse stakeholder groups into the planning process.

In response to the study’s findings, the report released recommends that large data gaps from insufficient groundwater monitoring be closed in order to decrease the risk that unsustainable groundwater use will harm underrepresented communities and the environment.

The report also makes recommendations to address the study’s finding that groundwater sustainability plans lack information about climate change impacts on water resources.

How Farmers Used California’s Floods to Revive Underground Aquifers

August 10, 2023

As an onslaught of storms soaked California with record-breaking rain last winter, Christine Gemperle found herself crisscrossing her almond orchards in knee-high muck boots and a slicker. She was out in the driving rain doing exactly what many farmers were trying to prevent: opening her irrigation gates and letting the flood rush into her orchards. …

For generations, during dry periods, California farmers have pumped water from deep underground to keep their crops hydrated when surface water supplies are scarce. Gemperle is no exception. Like many of her fellow farmers in California’s agricultural Central Valley, in dry years she turns to underground aquifers to irrigate the 135-acre almond farm she runs with her brother in Turlock.

But if farmers are the biggest takers of California’s dwindling groundwater supply, they are also becoming critical players in filling those aquifers back up. This year, Gemperle Orchards joined a growing number of farms helping to replenish overdrawn aquifers by flooding their orchards and fields with excess stormwater during wet seasons and letting it soak into the ground.

SGMA Inadequate Subbasins Update

August 10, 2023

By Geoff Vanden Heuvel, Director of Regulatory and Economic Affairs at the Milk Producers Council:

There is intense activity going on right now in the Groundwater Sustainability Agencies (GSAs) whose plans were deemed “inadequate” by the Department of Water Resources (DWR) this past spring. Sustainable Groundwater Management Act (SGMA) enforcement for the six inadequate subbasins was transferred to the State Water Resources Control Board (SWRCB).

A SWRCB staff report to the State Board last month had this summary: “the six basins with inadequate GSPs, from north to south, are the Chowchilla, Delta-Mendota, Kaweah, Tulare Lake, Tule, and Kern County subbasins. Deficiencies DWR noted include, but are not limited to, insufficient sustainable management criteria, the potential for dewatering of drinking water wells, impacts of subsidence, and lack of coordination amongst GSAs.”

Here is what I am learning from the public meetings I attend about where these subbasins are in addressing the items identified by DWR.

RESEARCH ARTICLE: From Drought to Deluge: Designing Groundwater Pricing Policies to Cope With California’s Water Woes

August 10, 2023

Groundwater pricing presents a promising tool for managing groundwater demand under California’s Sustainable Groundwater Management Act.

We use data from an agricultural region on the Central Coast to examine how farmers respond to an increase in price over a five-year period. We find that farmers are increasingly responsive to price over time.

RESEARCH ARTICLE: Recycled water could recharge aquifers in the Central Valley

August 10, 2023

Drawing out too much groundwater, or overdrafting, is a serious problem in California. As a result, groundwater sustainability agencies are considering using recycled municipal wastewater to recharge aquifers. In our study, we employ suitability mapping and the models C2VSimFG and Ichnos to identify appropriate areas for managing aquifer recharge with recycled water in California’s Central Valley.

The factors that influence suitability include soil properties, proximity to recycled water sources, and the residence time, or amount of time that recharged water spends underground. There are many suitable areas in the Central Valley that are immediately adjacent to water recycling facilities.

However, adequate supply is an issue in most locations. Roughly half of the groundwater sustainability agencies in critically overdrafted basins of the Central Valley have enough potentially suitable locations to meet their recharge goals, but not all of them have access to enough recycled water.

The methods demonstrated here can serve as tools for agencies considering using recycled water for aquifer recharge.

Can California cropland be repurposed for community solar?

“When you think of solar power, California undoubtedly comes to mind. The state’s strong climate goals paired with abundant sunshine have helped California reach record rooftop and utility-scale solar buildout. But surprisingly, its community solar programs (not to be confused with community choice aggregation) haven’t been able to gain traction.  Out of the 5,700 megawatts of installed community solar in the country, less than 1% of that is in California. And for perspective, California has more than 40,000 megawatts of installed solar capacity.  Unfortunately, the state’s current community solar programs haven’t been able to incentivize these projects. … ”  Read more from the Union of Concerned Scientists.

Sacramento Valley

Measuring and monitoring are essential to groundwater sustainability

“Each spring groundwater levels are measured throughout the Sacramento Valley, including here in Butte County.  As Watching Groundwater Level Recover in the Sacramento Valley noted earlier this year, water resources managers, Groundwater Sustainability Agencies (GSAs) and landowners throughout the Sacramento Valley are watching groundwater levels and quality to see how the aquifer systems will recover on the heels of some very dry years where there has been little surface water in certain parts of the Valley. We are seeing some encouraging trends on aquifer recovery in Butte County with the wet year and we will continue to monitor and collect important information to ensure the sustainable management of our groundwater resources. … ”  Read more from the Northern California Water Association.

SoCAL WATER DIALOG: SGMA implementation in the San Joaquin Valley

Groundwater is a critical resource, supplying nearly 40% of the state with water to support cities and farms.  With droughts increasing in severity and frequency and climate change putting stress on local communities across the state, it has become increasingly clear that California can no longer manage groundwater resources as we have in the past.  This recognition led to the passage of the Sustainable Groundwater Management Act (SGMA) in 2014 – a law designed to provide statewide guidance for managing California’s precious groundwater resources sustainably.  Eight years in, how is the implementation of SGMA going?

In a presentation to the Southern California Water Dialog, Ellen Hanak, vice president and director of the Water Policy Center and a senior fellow at the Public Policy Institute of California (PPIC), gave a status check on SGMA implementation with a focus on the San Joaquin Valley, which is ground zero for SGMA implementation.  In the San Joaquin Valley, bringing groundwater basins in to balance will necessitate significant amount of irrigated lands to come out of production.  Ann Hayden, Interim Vice President of Climate Resilient Water Systems for the Environmental Defense Fund, discussed how the state’s Multibenefit Land Repurposing Program hopes to help with the transition. … ”  Click here to read this article from Maven’s Notebook.

DWR Releases Decisions for Groundwater Management Plans in Critically Overdrafted Basins

March 6, 2023

Department of Water Resources Will Transmit Six Basin Determinations to State Water Board, Beginning State Intervention Process

From the Department of Water Resources:

The Department of Water Resources (DWR) today announced decisions for groundwater sustainability plans (GSPs) for 12 critically overdrafted groundwater basins in Central California. These plans provide a roadmap for how groundwater basins will reach long-term sustainability, while implementing near-term actions such as expanding monitoring programs, reporting annually on groundwater conditions, implementing groundwater recharge projects and designing allocation programs.

Of the 12, plans for six basins are recommended for approval with recommended corrective actions for the basins to remain in an approved status. The remaining six basins are deemed inadequate and are transitioning from DWR’s oversight to the State Water Board for State intervention under the Sustainable Groundwater Management Act (SGMA). Adopted in 2014, SGMA requires local groundwater sustainability agencies (GSAs) in medium- and high-priority groundwater basins, which includes 21 critically overdrafted basins, to develop and implement GSPs.

DWR recommends approval of plans for the following basins:

    • Cuyama Basin in Santa Barbara, San Luis Obispo, Ventura and Kern counties
    • Paso Robles Subbasin in San Luis Obispo County
    • Eastern San Joaquin Subbasin in San Joaquin County
    • Merced Subbasin in Merced County
    • Westside Subbasin in Fresno and Kings counties
    • Kings Subbasin in Fresno County

DWR deemed the following basin plans Inadequate:

    • Chowchilla Subbasin in Madera and Merced counties
    • Delta-Mendota Subbasin in San Joaquin, Stanislaus, Merced, Fresno, Madera, and San Benito counties
    • Kaweah Subbasin in Tulare and Kings counties
    • Tule Subbasin in Tulare County
    • Tulare Lake Subbasin in Kings County
    • Kern Subbasin in Kern County

GSAs are required to begin implementing their plans as soon as they are adopted locally, and these activities will continue even if basins are under State intervention. These plans will help local agencies address conditions that negatively impact groundwater within 20 years such as groundwater overdraft, degraded groundwater quality, land subsidence, and impacts to drinking water well users.

The GSAs whose plans are recommended for approval conducted critical analysis of groundwater levels, water quality and inter-connected surface waters to develop and refine sustainable groundwater management criteria. While additional analytical work is needed during implementation, DWR deemed the framework for management sufficient under the law.

“Since the onset of SGMA, local agencies have stepped up with dedication and progress in meeting critical milestones,” said DWR Director Karla Nemeth. “Protecting domestic wells, minimizing land subsidence and protecting groundwater resources are all State priorities. Implementation of these plans, which will require difficult adjustments as we go, will ultimately provide a safe and reliable groundwater supply for communities for generations to come.”

The basins deemed inadequate by DWR did not appropriately address deficiencies in how GSAs structured their sustainable management criteria. The management criteria provide an operating range for how groundwater levels prevent undesirable effects such as overdraft, land subsidence and groundwater levels that may impact drinking water wells, within 20 years. These GSAs did not analyze and justify continued groundwater level declines and land subsidence. Further, the GSPs lacked a clear understanding of how the management criteria may cause undesired effects on groundwater users in the basins or critical infrastructure.

In January 2022, after technical evaluation, DWR found the plans in these 12 critically overdrafted basins to be incomplete, identifying significant deficiencies that precluded approval. The GSAs had 180 days to correct the deficiencies and revise and resubmit their plans to DWR for re-evaluation, consistent with the regulations.

The basins with plans recommended for approval will continue to work with DWR and report on their progress in implementing their plans and completing corrective actions. DWR will transmit each basin deemed inadequate to the State Water Board, which may designate the basin probationary after providing public notice and then holding a public hearing. Any probationary designation will identify the deficiencies that led to intervention and potential actions to remedy the deficiencies. At the hearing, interested parties will have the opportunity to provide comments and technical information to the State Water Board regarding the deficiencies that were identified in the plans. Each basin is unique and will be evaluated individually by the State Water Board. State intervention and oversight is a critical step in making sure these basins succeed in achieving sustainable groundwater conditions. The ultimate goal is to have all basins return to local management with a clear path on how to achieve sustainability within 20 years of their original plan submittal.

DWR supports local agencies by providing planning, technical and financial assistance to help GSAs and local communities in this long-term effort to sustainably manage their groundwater basins. The critically overdrafted basins each received $7.6 million in Sustainable Groundwater Management grant funding to help them implement their plans. Complementary funding programs like DWR’s LandFlex program, state drought assistance programs, and the California Department of Conservation’s Multibenefit Land Repurposing program are helping the most critically overdrafted areas of the state reduce their dependence on groundwater and fast-track progress in reaching local sustainability goals.

Out of a total of 94 groundwater basins required to submit plans under SGMA, DWR has provided determinations for 24 basins and is currently reviewing an additional 61 plans from 59 of the state’s high- and medium- priority basins that were submitted to DWR in January 2022. DWR anticipates issuing determinations for the remaining basins throughout 2023.
