Statement of Findings regarding the Determination of Incomplete Status of the Santa Clara River Valley – Piru Subbasin Groundwater Sustainability Plan

California Department of Water Resources (DWR) | January 18th, 2024

The Department of Water Resources (Department) is required to evaluate whether a submitted groundwater sustainability plan (GSP or Plan) conforms to specific requirements

The Department of Water Resources (Department) is required to evaluate whether a submitted groundwater sustainability plan (GSP or Plan) conforms to specific requirements of the Sustainable Groundwater Management Act (SGMA or Act), is likely to achieve the sustainability goal for the Subbasin, and whether the GSP adversely affects the ability of an adjacent basin or subbasin to implement its GSP or impedes achievement of sustainability goals in an adjacent basin or subbasin. (Water Code § 10733.) The Department is directed to issue an assessment of the GSP within two years of its submission. (Water Code § 10733.4.) This Statement of Findings explains the Department’s decision regarding the submitted Plan by the Fillmore and Piru Basins Groundwater Sustainability Agency (GSA or Agency) for the Santa Clara River Valley – Piru Subbasin (No. 4-004.06).

Statements of Water Diversions and Use: Providing a Better Picture of Water Use in the Delta

The purpose of this report is to outline the history of the Statements Program and explain recent statutory changes that will enable the program to more comprehensively fulfill its original intent of providing meaningful information regarding water diversion and use, particularly in the Delta. The report also underscores a serious funding problem that threatens the integrity of the Statements Program and explores issues related to the new requirement for diverters to provide monthly records of water diversion based on the use of best available technologies.

Statutory Water Rights Law And Related California Code Sections (As amended, including Statutes 2016)

California State Water Resources Control Board (SWRCB) | March 30th, 2017

The State Water Resources Control Board publishes this collection of California statutes pertaining to the law of water rights as part of its public information program.

The State Water Resources Control Board publishes this collection of California statutes pertaining to the law of water rights as part of its public information program. This booklet contains sections from the California Constitution, the California Water Code, and other related codes which affect water rights decisions. This booklet is provided as a public service. It contains only excerpts of the Water Code. While every effort is made to assure accuracy, persons should consult the official version of the California Code when making legal decisions. The California Legislative Counsel maintains the official code, which is accessible on the Internet at: http://leginfo.legislature.ca.gov/faces/codes.xhtml. In addition to the statutes contained in this booklet, decisions of the State Water Resources Control Board are guided by case law. A listing of major recent decisions is included. In general, the statutes contained in this booklet govern the acquisition and exercise of rights to reasonable and beneficial use of surface waters (and of groundwater flowing in known and definite channels) by priority of appropriation initiated on or after December 19, 1914. That is the effective date of the Water Commission Act, which is the origin of many of the water right provisions of today’s Water Code.

Supreme Court Declines to Review Ninth Circuit Decision Applying Federal Reserved Water Rights Doctrine to Groundwater

Congressional Research Service (CRS) | December 21st, 2017

The 2012-2016 drought in California and parts of other western states may have ended, but availability of water will continue to present issues for Cong

The 2012-2016 drought in California and parts of other western states may have ended, but availability of water will continue to present issues for Congress to consider. While state, rather than federal , law typically governs allocations of water resources within a state , there are exceptions where federal law does affect water allocation. Thefederal reserved water rights doctrine, for example, holds that when the federal government reserves federal lands for a particular purpose (such as for a tribal reservation or national monument ) , it impliedly reserves a right to water necessary to accomplish the purposes for which the reservation was created . Si nce 1908, when the Supreme Court established the doctrine in Winters v. United States, courts have applied it to surface waters; a March 2017 decision of the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit) held, apparently for the first time, that the doctrine can encompass groundwater as well. On November 27, 2017, the Supreme Court declined to review this decision, which thus, for now, sets a potentially important precedent within the Ninth Circuit for other groundwater resource issues and disputes. The case Agua Caliente Band of Cahuilla Indians v. Coachella Valley Water District originated w hen a tribe sued local water agencies in 2013 in federal district court in California, alleging that the water agencies were adversely affecting the quantity and quality of water available to them by over-drafting an aquifer. Among other claims, the tribe sought a declaration that it had a federally reserved right to the groundwater underlying the reservation , which was established in the 1870s. The United States intervened to defend its ownership, tribal trust, and sovereign interests in the water rights and the tribe’s reservation. In 2015, t he district court ruled in favor of the tribe and the United States on the threshold claim that the government impliedly reserved appurtenant water sources — including underlying groundwater — when it created the tribe’ s reservation . (Subsequent phases of the Agua Caliente Band case are still being litigated. They involve whether the tribe owns the “pore space” or “storage space” of the groundwater basin.

Targeting Public Trust Suits

Social Science Research Network (SSRN) | February 22nd, 2021

The California public trust doctrine empowers private individuals and interest groups to protect the public trust and to enforce state laws that protect the public trust.

The California public trust doctrine empowers private individuals and interest groups to protect the public trust and to enforce state laws that protect the public trust. California has long led the development of the doctrine in the United States, becoming the first state to allow citizen suits to protect the public trust in 1971. A number of other states have followed California’s lead, resulting in a significant expansion in environmental standing. This broadened standing seems to be settled law. In contrast, two California Court of Appeal decisions create some uncertainty about appropriate defendants in public trust lawsuits. These decisions counsel some caution as private parties pick their targets for public trust litigation.

Tehachapi-Cummings County Water District (TCCWD) v. Armstrong et al

Superior Court of California, County of Kern | February 25th, 1972

From An Evaluation of California’s Adjudicated Groundwater Basins by Langridge et al, UC Davis (2016): "Tehachapi Basin (1, 2) , Cummings Basin, and Brite Basin are three small groundwater basins in Kern County. Although the basins were adjudicated separately, a single entity, The Tehachapi-Cummings County Water District (TCCWD) serves as Watermaster over the three distinct groundwater basins. An interesting finding is that the Cummings adjudication was never completed. Because of this, its users rely on overlying rights with voluntary agreements, and there is no regulated curtailment of withdrawals. There are only a few big users so it is able to track its water use with relative accuracy, but the basin has significant overdraft. Two of its major users (Stallion Springs and Bear Valley) pump water from the basin that is delivered to offsite users, and they offset the export with imported water. Two-thirds of the residents within Cummings Basin are inmates at the California Correctional Institute."
