Abstract: The Colorado River Board of California was created by legislation in 1937 (Chapter 838). The records of the Board consist
of two series: Office Files (1949-1953), which document the activities and functions of the Board, and Newspaper Clippings
(1960-1966), which highlight significant news stories pertaining to actions of the Board and to Colorado River water rights
and access issues.

Acquisition and Custodial History
The State Archives received these records in a series of transfers according to state law.
The Colorado River Board of California was created in 1937 (Chapter 838) to protect the rights and interests of the State
of California, its agencies and citizens, in and to the waters of the Colorado River system. The maximum use of Colorado River
water is essential to the development of nearly one million acres of agricultural land in the Palo Verde, Imperial and Coachella
valleys, and to the domestic, industrial, and municipal water supply for the metropolitan areas of coastal southern California.
California’s interest in the water system of the Colorado River has a long history. In 1921, the Governor was authorized to
appoint a representative to an interstate commission for the purpose of negotiating a compact relating to the Colorado River.
This resulted in the Colorado River Compact, which was signed on November 24, 1922, and settled some of the general issues,
such as division of water between the upper basin and lower basin, but left unresolved the division of water among the states.
In 1925, an attempt was made to divide the water rights among the lower basin states (California, Arizona, and Nevada), but
As the Boulder Canyon Project Act neared completion, the urgency to reach an agreement increased. A Colorado River Commission
was created in 1927 (Chapter 596) to represent the state’s interest, but it soon lapsed with the construction of Hoover Dam,
presumably on the basis that it was no longer needed. However, increasing friction led to litigation and three lawsuits were
filed by Arizona against California and other states during the years 1931-1936. These lawsuits were successfully defended.
As the burden to protect the state’s rights to the river became more pressing and time-consuming, it became necessary to create
a separate agency. Thus, the Colorado River Board was given an advisory role to a Colorado River Commissioner, who would have
the general function of investigating issues and providing information about the water system, and reporting and recommending
to the Governor as appropriate.
In 1940, the duties of the Commissioner were made subject to the direction of the Board. The Board initially consisted of
six members appointed by the Governor, one representative from each of the agencies including the Metropolitan Water District
of Southern California, Department of Water and Power – City of Los Angeles, San Diego County Water Authority, Imperial Irrigation
District, Coachella Valley County Water District, and the Palo Verde Irrigation District. The Board represents the state before
congressional committees, federal agencies, and in negotiations with other Colorado River basin states. The staff of the Board,
consisting mainly of engineers, collects, compiles, and analyzes engineering and legal data on the existing and proposed division
and apportionment of the Colorado River waters. In more recent times, the Governor was given authority to add four members
to the Board, two from the general public, and the Directors of the Departments of Water Resources and Fish and Game.
For the most part, the work of the Board has focused on sources of conflict over the use of the water system. The problem
with Arizona has a lengthy and troublesome history, which relates to the interpretation of the Colorado River Compact, the
Boulder Canyon Project Act, and the Mexican Treaty of 1945. In 1952, Arizona filed suit in the United Sates Supreme Court
against California and the six agencies of the Board. In 1963, the Court ruled in Arizona’s favor, which significantly curtailed
California’s quota of water. The Court determined that in years when the flow of the river was 7.5 million acre-feet or more,
the water would be apportioned as follows: 4.4 million acre-feet to California; 2.8 million acre-feet to Arizona; and the
reminder to Nevada. This has formed the foundation for distribution of the lower Colorado River waters. As other projects
have arisen, various meetings and discussions have been held among the three states and the federal government. The Court,
however, did not decide how to distribute the water in years when the overall flow is less than 7.5 million acre-feet, but
left this issue to a determination by the U. S. Secretary of the Interior. In most years, the Secretary has transferred unused
portions of other state allotments to make up for California’s shortage.
Scope and Content
The Colorado River Board of California records consist of one and a half cubic feet of textual records covering the period
from 1949-1966, with a record gap existing between 1953-1966. The collection is organized into two series: Office Files and
Newspaper Clippings. The records contain correspondence, memoranda, meeting schedules, agendas, minutes, rosters, reports,
speeches, resolutions, hearing summaries, operational data, weekly bulletins, summaries of news events, legislative summaries,
public relations files, and newspaper clippings.
In this collection researchers will find interesting materials on the history and functions of the Colorado River Board. The
Office Files series contains a variety of documentation of the Board’s activities during the late-1940s and early-1950s. The
materials provide insight into the disputes, policies, decisions, and activities of the Board during this period. The Newspaper
Clippings series contains significant news stories and issues concerning the lower Colorado River during the early to late
1960s. Some of the article topics include: atomic energy, Arizona water projects, Bridge Canyon Dam, Bureau of Reclamation,
California v. Arizona suit, Central Valley Project (CVP), Colorado River Storage Project, drought, Glen Canyon Dam, Hoover
Dam, Lake Mead, rainfall, and water supply.
Further accruals are expected.
