Groundwater Trading as a Tool for Implementing California’s Sustainable Groundwater Management Act

Until recently, the State of California lacked comprehensive groundwater management policy. While many basins havebeen adjudicated in court or have adopted voluntary groundwater management programs following Assembly Bill 3030 and Senate Bill 1938, the vast majority of groundwater use remained unregulated. In 2014, the State Legislature passed the landmark Sustainable Groundwater Management Act (SGMA) in response to wide-ranging consequences of prolonged and unchecked groundwater pumping. While groundwater serves as an important primary and supplemental water supply for many water users, over-pumping can result in negative consequences, six of which are listed as “undesirable results” under SGMA: chronic aquifer overdraft, reduction of groundwater storage, seawater intrusion, degradation of water quality, land subsidence, and depletion of hydrologically connected surface water. SGMA requires local Groundwater Sustainability Agencies (GSAs) to develop and implement Groundwater Sustainability Plans (GSPs) to manage groundwater to avoid such consequences. To meet the requirements of SGMA, GSAs will need to employ a wide range of management tools. This paper focuses on one set of these tools: groundwater trading programs. Trading goes by many different names, including markets, cap and trade, transfers, credit programs, banking, pooling, and exchanges. For the purposes of this paper, we have elected to use the terms “trading” and “trading programs” as the broader categorization of incentive-based management tools. Trading can be executed through a wide range of exchange vehicles, including short- and long-term leases, permanent transfers, and other more advanced or unique arrangements, such as inter-annual water exchanges or dry-year options contracts.

Guidance Document for Groundwater Sustainability Plan Stakeholder Communicaton and Engagement, June 2017 (Draft)

California Department of Water Resources (DWR) | June 1st, 2017

The objectve of this guidance document is to provide Groundwater Sustainability Agencies (GSAs) information to aid with stakeholder communication and engage

The objectve of this guidance document is to provide Groundwater Sustainability Agencies (GSAs) information to aid with stakeholder communication and engagement for Groundwater Sustainability Plan (GSP) preparation and to provide examples and existing resources related to public engagement and effective communication for Sustainable Groundwater Management Act (SGMA) implementation. Limitation and use of this guidance information This guidance document is not intended to prescribe specifc outreach and communications methods for GSAs or local agencies to follow, but to provide resources and various examples for consideration. This guidance document also summarizes the public notfcation requirements that GSAs must adhere to in order to comply with SGMA and the GSP regulations. Other than what is required by statute or regulation, GSAs have discretion on how they communicate and engage with the beneficial uses and users of groundwater within a basin.

Guidance Document for the Sustainable Management of Groundwater Engagement with Tribal Governments June 2017 (Draft)

California Department of Water Resources (DWR) | June 1st, 2017

The objective of this guidance document is to convey information, as provided by California’s Tribal governments, by which local agencies can engage Tribal governments as part of an effort to identify interested persons, and consider the interests of beneficial users of groundwater; including those users on Tribal lands not subject to the Sustainable Groundwater Management Act (SGMA). This guidance document can also be used to help local agencies engage with a Tribal government in the planning, financing, and management of a Groundwater Sustainability Agency (GSA), or help with the development and implementation of a Groundwater Sustainability Plan (GSP) pursuant to SGMA.

Guidance for Climate Change Data Use During Groundwater Sustainability Plan Development

California Department of Water Resources (DWR) | April 12th, 2018

This Guidance Document was developed to help Groundwater Sustainability Agencies (GSAs) incorporate California Department of Water Resources (DWR)-provided climate change

This Guidance Document was developed to help Groundwater Sustainability Agencies (GSAs) incorporate California Department of Water Resources (DWR)-provided climate change and related data into their Groundwater Sustainability Plans (GSPs). The purpose of this Guidance Document is as follows: • Provide relevant data and tools for GSAs to incorporate climate change into their GSPs. • Provide an analysis approach using the provided data and tools that incorporates the best available science and best available information to date. This Guidance Document focuses on the use of DWR-provided climate change data and provides documentation about the following: • Climate change data development approach • Climate change data development methods and processes • Applications for using the provided climate change data • Climate change data assumptions and limitations This Guidance Document provides a process for using DWR-provided climate change data for computing projected water budgets and serves as a companion document to the water budget best management practices (BMPs)2 and the modeling BMP3. For Sustainable Groundwater Management Act (SGMA) implementation purposes, the use of climate change data can help with the following: • Developing projected water budgets • Long-term planning of groundwater basin sustainability • Assessing projects and management actions by performing sensitivity analyses of projected conditions • Adaptive Management

Henry Miller Water District Revised Groundwater Sustainability Plan, Kern County Subbasin

Henry Miller Water District | July 21st, 2022

This Groundwater Sustainability Plan (GSP) for the Henry Miller Water District (HMWD) Groundwater Sustainability Agency (GSA) has been prepared pursuant to Water Code §1

This Groundwater Sustainability Plan (GSP) for the Henry Miller Water District (HMWD) Groundwater Sustainability Agency (GSA) has been prepared pursuant to Water Code §10727. HMWD is located in the Kern County Subbasin (Basin 5-22.14) as defined by the Department of Water Resources’ (DWR) Bulletin 118. The Kern Subbasin is considered to be in a condition of critical overdraft and has been designated as a high priority basin. This GSP is one of the five GSPs being prepared in the Subbasin, which collectively has and will coordinate to avoid, to the best of their abilities, any and all Undesirable Results as a result of unsustainable groundwater management practices. HMWD formed its own GSA on March 15, 2017; it is the only Water District located within the GSA. HMWD GSA is one of five GSAs that are preparing a GSP within the Subbasin. This GSP, in coordination with the four other GSPs within the Subbasin, will provide a path to sustainability and the preservation of groundwater resources for all beneficial users of groundwater. Because the Subbasin has multiple GSPs, the GSPs are prepared under a coordination agreement. This Coordination Agreement exemplifies the ways that the various GSPs were able to work together to achieve a common goal: groundwater sustainability for the Subbasin. For example, the entire Subbasin has utilized Todd Groundwater’s services to analyze historic, current, and future groundwater conditions with a C2VSIM model. This Plan includes a description of the historic groundwater conditions in the Subbasin, a Subbasin water budget, sustainable management criteria for future monitoring, and projects and/or management actions that may be implemented to ensure groundwater sustainability is achieved by 2040 and maintained through 2070. Due to size, the file has been divided. Part 1, Part 2, Part 3, Part 4, Part 5
