This document provides guidance to groundwater sustainability agencies (GSAs) preparing Annual Reports, Periodic Evaluations, and Groundwater Sustainability Plan (GSP or Plan) Amendments under the Sustainable Groundwater Management Act (SGMA or Act) and the GSP Regulations. This guidance document does not create any new requirements or obligations for GSAs but is intended to clarify the necessary content of the documents already required by SGMA and the GSP Regulations.

The Los Molinos Subbasin (DWR Subbasin No. 5-021.56) of the Sacramento Valley Groundwater Basin was assigned a medium priority designation by DWR and is required to submit a GSP. The Tehama County Flood Control and Water Conservation District (Tehama County FCWCD) (District), a local and regional authority, serves as the exclusive GSA for the Los Molinos subbasin.

Groundwater Technical Procedures of the U.S. Geological Survey

A series of groundwater technical procedures documents (GWPDs) has been released by the U.S. Geological Survey, Water-Resources Discipline, for general use by the public. These technical procedures were written in response to the need for standardized technical procedures of many aspects of groundwater science, including site and measuring-point establishment, measurement of water levels, and measurement of well discharge. The techniques are described in the GWPDs in concise language and are accompanied by necessary figures and tables derived from cited manuals, reports, and other documents. Because a goal of this series of procedures is to remain current with the state of the science, and because procedures change over time, this report is released in an online format only. As new procedures are developed and released, they will be linked to this document.

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.
