Delta Conveyance Project
proposed tunnel in California
The Delta Conveyance Project, formerly known as California WaterFix and EcoRestore or the Bay Delta Conservation Plan, is a $20 billion plan proposed by Governor Jerry Brown and the California Department of Water Resources to build a 36 foot (11 m) diameter tunnel to carry fresh water from the Sacramento River southward under the Sacramento-San Joaquin Delta to Bethany Reservoir for use by the State Water Project and the Central Valley Project.
Project History
The precipitation in the northern part of the state has long been diverted by federal and state water projects to the southern portion of the state for agriculture and urban use. In the 1960s, Governor Pat Brown supported two large projects that reallocated water from the northern portion of the state to Southern California. In the early 1980s, his son, Governor Jerry Brown, attempted a third, the Peripheral Canal, which failed to gain voter support. Governor Arnold Schwarzenegger pushed for the project in 2009 and, when Jerry Brown returned to office as governor in January 2011, he made it one of his two main focuses during his eight years in office. During those years, the project morphed from an above-the-ground "peripheral canal" to two huge underground tunnels referred to as the "twin tunnels." The twin tunnel project was finally stopped in 2018 through the work of Delta citizens and support organizations. Governor Gavin Newsom began pushing for a single tunnel project when he took office in 2019.
Central Valley Project and State Water Project
The Central Valley Project (CVP) is a federally owned and operated project completed in the 1970s. It has 600 miles (970 km) of canals and moves up to 13 million acre feet per year and generates electricity—about half of which is used by the system. Overall, depending on the weather and amount of rain, up to 80% of water in the state is used for agriculture.
This brief starts where responsible research should: with the source description of “Delta Conveyance Project” as proposed tunnel in California. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as proposed tunnel in California. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 24, 2026. The linked authority identifier is Q20486989. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009, 2011, 2018 and 2019.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
