From Maven’s Notebook:
As groundwater sustainability agencies prepare their plans to meet the requirements of the Sustainable Groundwater Management Act (SGMA), they will likely utilize a variety of tools to achieve sustainability. In many subbasins, groundwater overdraft conditions will require GSAs to impose reductions in pumping in order to achieve sustainable conditions in the subbasin. To do this, GSAs will need set a limit or “cap” on the overall amount of groundwater that is removed from the subbasin, assigning portions of this capped amount to groundwater pumpers in the form of a pumping allocation.
Making pumping allocation decisions will be a difficult task for GSAs, as it will require restricting access to groundwater resources upon which the agricultural community, cities and towns, and others depend. Adding further complexity to the task, SGMA explicitly states that it does not alter water rights, which means groundwater sustainability agencies have to carefully navigate between the confines of water rights and SGMA requirements in developing and implementing their groundwater sustainability plans.
At the 3rd annual Western Groundwater Congress, hosted online by the Groundwater Resources Association of California in September of 2020, Dr. William Blomquist, a Professor of Political Science and more at Indiana University-Purdue University Indianapolis, gave a presentation of ongoing research he is doing with Dr. Christina Babbitt, California Groundwater Manager at the Environmental Defense Fund looking at how other groundwater basins have developed groundwater allocations.

Eric Averett is general manager of the Rosedale-Rio Bravo Water Storage District in Kern County, California, which is one of 21 regions required by the state to balance groundwater demand and supply within 20 years under the Sustainable Groundwater Management Act.
Rosedale is home to approximately 27,500 acres of irrigated cropland and 7,500 acres of urban development. Groundwater demand there exceeds supply by approximately 5,000 acre-feet per year.
To inform landowners about their water budgets, Rosedale partnered with EDF, Sitka Technology Group, WestWater Research and local landowners to co-develop a new online, open-source water accounting and trading platform.
We asked Eric to answer a few questions about how the platform will help local landowners and how it can be expanded to other parts of the Central Valley.

From the Public Policy Institute of California:
Over-pumping of groundwater has caused domestic wells to go dry in the San Joaquin Valley. Yet many of the first round of plans prepared to comply with the Sustainable Groundwater Management Act (SGMA) do not yet propose ways to address this problem. We explored groundwater planning with three members of the environmental justice community—Angela Islas of Self-Help Enterprises, Justine Massey of the Community Water Center, and Amanda Monaco of the Leadership Counsel for Justice and Accountability.

From the Water Foundation:
Through the NGO Groundwater Collaborative, non-governmental organizations (NGOs), Tribes, and California residents share information and resources to help each other participate in the state’s groundwater management programs. We spoke with Jennifer Clary, California Director for Clean Water Action California, and Emily Finnegan, Project Manager for Local Government Commission’s water programs, about the collaborative and what’s coming up for the group.

The groundwater sustainability plans that were submitted to the Department of Water Resources in January of 2020 were the first of the groundwater sustainability plans to be completed. Public review of these plans has revealed some important lessons to be learned to be considered for those preparing the plans that will be due in January of 2022. At the 3rd Annual Groundwater Sustainability Agency Summit hosted by the Groundwater Resources Association online in June, a panel of NGOs that had completed a review of the plans summarized their findings from the perspective of underrepresented beneficial users and with respect to stakeholder engagement, providing insights and recommendations for the upcoming plans.
The implementation phase of the Sustainable Groundwater Management Act has now begun for the basins designated as critically-overdrafted. Getting to this point has been an unparalleled journey as communities, farmers, water suppliers, and others navigated through uncharted territory to develop local solutions for sustainable groundwater management. At the Groundwater Resources Association Third Annual Groundwater Sustainability Agency Summit held online in June, a panel of managers from four of the critically overdrafted basins reflected on the hard work of developing and adopting a groundwater sustainability plan.
Seated on the panel were Gary Petersen from the Salinas Valley Basin GSA; Eric Osterling from the Mid Kaweah GSA; Deanna Jackson from TriCounty GSA; and Patricia Poire from the Kern Groundwater Authority. Collectively, these GSAs are having to deal with all six of the undesirable results, from subsidence to groundwater levels to seawater intrusion, and they overly five of the 21 critically overdrafted basins.
Each panelist then discussed the process that they went through in developing their plans, the lessons they learned, and their advice for those developing the plans that will be due in January of 2022.
At the end of January of this year, the state’s critically overdrafted groundwater basins submitted their adopted groundwater sustainability plans (or GSPs), meeting an important deadline in the Sustainable Groundwater Management Act; the remaining basins subject to SGMA will be submitting their plans in January of 2022. The Department of Water Resources will now have two years to review the plans to determine their adequacy.
At the Third Annual GSA Summit, Craig Altare, chief of the Groundwater Sustainability Plan section at the Department of Water Resources’ Sustainable Groundwater Management Office or SGMO, reflected on the GSPs and how the implementation of SGMA is playing out.
Dr. Thomas Harter provides a basic understanding of groundwater – what it is, how much groundwater is out there, how fast groundwater moves, and where it comes from and where it goes
Groundwater is an important part of California’s – and the nation’s water supply. Nationwide, groundwater makes up on average 26% of the water supply. In California, that number is significantly higher – groundwater provides nearly 40% of the water used by California’s farms and cities, and significantly more in dry years. But what is groundwater? In this post based on the first segment of the UC Davis shortcourse on groundwater, Dr. Thomas Harter, who is the Robert M. Hagan Endowed Chair for Water Resources Management and Policy at the University of California, Davis as well as Professor and Cooperative Extension Specialist in the Department of Land, Air, and Water Resources (among many other things), provides a basic understanding of groundwater – what it is, how much groundwater is out there, how fast groundwater moves, and where it comes from and where it goes.
In these extraordinary times, managing groundwater for long-term sustainability may not seem like a top priority. But in the San Joaquin Valley—where groundwater supplies have been declining for decades—excess pumping is a critical problem, with major implications for public health, jobs, the environment, and local economies.
The state’s Sustainable Groundwater Management Act (SGMA) requires groundwater planning and actions to sustain this vital resource. Agencies from California’s 21 “critically overdrafted” basins—including 11 large basins that span most of the San Joaquin Valley floor—submitted their first groundwater plans in January.
As part of our long-term work to build shared understanding of water challenges and solutions in the valley, the Public Policy Institute of California reviewed the 36 plans developed for these basins to see how well they tackle some key issues.
