The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)

Covered Actions

The Delta Reform Act of 2009 (Act) established a self-certification process for demonstrating consistency with the Delta Plan. This means that state and local agencies proposing to undertake a qualifying action, called a “covered action” in the Act, must submit to the Council, a written certification of consistency with detailed findings as to whether the covered action is consistent with the Delta Plan.

Per Water Code section 85057.5 “covered action” means a plan, program, or project as defined pursuant to Section 21065 of the Public Resources Code that meets all of the following conditions:

  • Will occur, in whole or in part, within the boundaries of the Delta or Suisun Marsh.
  • Will be carried out, approved, or funded by the state or a local public agency.
  • Is covered by one or more provisions of the Delta Plan.
  • Will have a significant impact on achievement of one or both of the coequal goals or the implementation of government-sponsored flood control programs to reduce risks to people, property, and state interests in the Delta.

Any state or local public agency proposing to undertake a covered action is encouraged to consult with the council at the earliest possible opportunity, preferably no later than 30 days before submitting its certification to the Council.

The tabs below provide detailed information for the different phases of the covered actions process. Click on the tabs below to preview additional details about those phases.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).


Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.


There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.

The Delta

The Sacramento-San Joaquin Delta is a regional, state and national treasure that supplies the drinking water of about 25 million Californians.

More than 515,000 people in dozens of communities call the Delta home. It is also home to more than 750 animal and plant species, some of them threatened or endangered. It supports California’s $27 billion agricultural industry with an average annual gross value of more than $500 million in corn, grain, hay, sugar beets, alfalfa, pasture, tomatoes, asparagus, safflower, a range of fruits and more. More than 1,800 agricultural users draw water from the Delta.

It is also the hub of state, federal and local water systems that provide at least a portion of the water supply needs for two-thirds of all Californians. Diversions directly from the Delta include the State Water Project, the federal Central Valley Project, the Contra Costa Canal, the North Bay Aqueduct, the City of Vallejo and the Western Delta Industry.

The Delta is also a world-class recreational destination, attracting about 12 million visitors per year, who take advantage of its 290 shoreline recreational areas, 300 marinas, 57,000 navigable waterways and more than 20 species of sport fish.

But for all its significant attributes, the Delta also faces significant challenges. Over several decades, the competing demands for the Delta to provide both habitat and water supply have impaired the Delta’s ability to meet either need. The needs of the ecosystem and water users particularly clash during dry years, when there is simply less water to go around.

Many factors have contributed to the Delta’s decline. Agricultural, industrial and urban runoff has polluted its waters. Invasive, non-native species have adversely impacted the food chain and, as a result, native fish and wildlife populations suffer.

Gradual changes, such as sea level rise, rising water temperatures due to climate change, or additional invasions of exotic species, could also transform the current ecosystem in ways that are difficult to anticipate or manage. Some climate change projections indicate a likelihood of more frequent and intense storms. These conditions, combined with the aging levees, increase the risk of levee failure. Massive levee failures could be difficult to repair and cause saltwater intrusion into the Delta that could only be reversed over a long period of time using high volumes of fresh water from upstream reservoirs or storms. Increased salinity would substantially degrade the Delta aquatic habitat, Delta water supplies, Delta agriculture and recreation.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

The Delta Stewardship Council must adopt and implement a comprehensive management plan for the Sacramento-San Joaquin Delta by January 1, 2012. This Delta Plan will guide state and local agencies to help achieve the coequal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The Delta Plan will also guide protection and enhancement of the unique resources, culture, and values of the Delta as an evolving place.

See Delta Water Legislation 2009 for more info.

The council has an acutely focused mission and a legislatively mandated timeline to develop the Delta Plan, prepare an Environmental Impact Report, and implement strategies that will address the crisis in the Delta. See CEQA page for timeline.

The council is committed to maintaining transparency in its decision-making processes, and will educate and reach out to all interested Californians as the Delta Plan is developed. Public input is welcomed on an ongoing basis. In developing the Delta Plan, the council will also consult with federal, state, and local agencies with responsibilities in the Delta, as required by legislation.

The first draft of the Delta Plan is under development and will be available for public review in early 2011. Materials reviewed by the council during development of the Delta Plan will be posted as they become available. Once adopted, the Delta Plan will be reviewed at least once every five years.


Visit Interim Plan

Prior to adopting the Delta Plan, an Interim Plan is being developed to guide the Council during development of the Delta Plan. The Interim Plan includes procedures and tools the Council will use to make recommendations for early actions, projects, and programs. The Council then will begin work on the Delta Plan and the environmental review process required under the California Environmental Quality Act (CEQA). The Council has convened public workgroups as a means of soliciting input that will assist the council in developing the Interim Plan and Delta Plan.
