Protocol for Closure of Delta Waterways

Office of Emergency Services | November 21st, 1997

This protocol describes the process for placing restrictions on vessel traffic on the San Joaquin/Sacramento Delta waterways during periods of high water levels and flood

This protocol describes the process for placing restrictions on vessel traffic on the San Joaquin/Sacramento Delta waterways during periods of high water levels and flood events that involve conditions of disaster or extreme peril to the safety of persons and property. Restrictions will provide for flood fight priorities and control of vessel wakes that may exacerbate levee erosion or overtopping.

Risks and Options to Reduce Risks to Fishery and Water Supply Uses of the Sacramento/San Joaquin Delta

California Department of Water Resources (DWR) | January 1st, 2008

Assembly Bill (AB) 1200 (Laird, Chapter 573, Statutes of 2005) highlighted the complex Delta water issues, and directed the Department of Water Resources (DWR) and the Department of Fish and Game (DFG) to report to the Legislature and Governor on the following: • Potential impacts of levee failures on water supplies derived from the Sacramento-San Joaquin Delta due to future subsidence, earthquakes, floods, and effects of climate change • Options to reduce the impacts of these factors • Options to restore salmon and other fisheries that use the Delta estuary The State is currently involved in four major planning efforts to evaluate ecosystem and water supply issues and consider options for improvements: 1. The Delta Risk Management Strategy (DRMS) is evaluating Delta issues primarily from the perspective of the risks from levee failures and ways to reduce those risks 2. The CALFED Ecosystem Restoration Program (ERP) Conservation Strategy is identifying restoration opportunities within the Delta and Suisun Marsh ecological restoration zones based on existing elevations, soil types, habitats and natural process requirements of pelagic organisms and other native fish species 3. The Delta Vision will develop a durable vision for sustainable management of the Delta with the goal of managing the Delta over the long term to restore and maintain identified functions and values that are determined to be important to the environmental quality of the Delta and the economic and social well being of the people of the state 4. The Bay Delta Conservation Plan (BDCP) is evaluating Delta issues primarily for the goal of obtaining permits for water supply operations through a comprehensive conservation plan for the Delta designed to protect and restore at-risk species. Since each process has only prepared initial findings at this point in time, this document reports on progress made to define the risks and options to reduce risks for the Delta as requested by the Legislature.

Sacramento County | Making Room for Recharge: Cosumnes River Levee Removal and Floodplain Restoration

Nature Conservancy | June 12th, 2014

Reconnecting rivers to floodplains can facilitate groundwater recharge. A recent project along the Cosumnes River is one of the first to intentionally demonstra

Reconnecting rivers to floodplains can facilitate groundwater recharge. A recent project along the Cosumnes River is one of the first to intentionally demonstrate this recharge benefit. While this project was expensive and more complex than many forms of recharge, public funding paid for the project and a partnership with UC Davis is improving the understanding of groundwater-surface water interactions and basin groundwater conditions. In 2014, The Nature Conservancy piloted this concept by selectively removing portions of a private levee system along the Cosumnes River to enhance floodplain processes and restore approximately 500 acres of riparian habitat. The levee removal project offers multiple environmental benefits, including increased groundwater recharge in the floodplain.

San Francisco Bay Shore Inventory Mapping for Sea Level Rise Planning

San Francisco Estuary Institute (SFEI) | April 5th, 2016

With rising sea levels and the increased likelihood of extreme weather events, it is important for regional agencies and local municipalities in the San Francisco Bay Are

With rising sea levels and the increased likelihood of extreme weather events, it is important for regional agencies and local municipalities in the San Francisco Bay Area to have a clear understanding of the status, composition, condition, and elevation of our current Bay shore, including both natural features and built infrastructure. The purpose of this Bay shore inventory is to create a comprehensive and consistent picture of today’s Bay shore features to inform regional planning. This dataset includes both structures engineered expressly for flood risk management (such as accredited levees) and features that affect flooding at the shore but are not designed or maintained for this purpose (such as berms, road embankments, and marshes). This mapping covers as much of the ‘real world’ influence on flooding and flood routing as possible, including the large number of non-accredited structures. This information is needed to: 1. identify areas vulnerable to flooding; 2. identify adaptation constraints due to present Bay shore alignments; and 3. suggest opportunities where beaches, wetlands, and floodplains can be maintained or restored and integrated into flood risk management strategies.

Skarry Removal

The Commission’s contractor will remove booms, winches, and other superstructures from the crane barges on site. This equipment will be cut into pieces and placed on a materials barge for recycling. Floating booms will surround the work site and contain any debris. Once lightened of equipment, a crane will remove the two smaller barges directly from the water. The largest barge will be refloated and towed by water to the Mare Island shipyard, where it will be removed from the water and demolished. Scrap metal will be recycled, and other debris will be hauled to a landfill for disposal. Click here for the staff report that accompanied the plan.

Sniffing the Delta for Greenhouse Gases

Global food production contributes an estimated 21% to 37% of the greenhouse gases that are warming the planet, including huge releases of carbon when vast aquatic ecosystems like the Delta are transformed for agriculture. [Dennis] Baldocchi and colleagues are now trying to figure out if bringing back tidal wetlands like the one at Dutch Slough can help reverse these processes.

State Investments in Delta Levees

Delta Stewardship Council (Delta Council) | January 1st, 2015

This 43-page Issue Paper, authored by Dustin Jones, the Council's Integrated Regional Water Management Supervising Engineer, is entitled State Investments in Delta Levees

This 43-page Issue Paper, authored by Dustin Jones, the Council's Integrated Regional Water Management Supervising Engineer, is entitled State Investments in Delta Levees, Key Issues for Updating Priorities. The Delta Reform Act requires that the Delta Plan promote strategic levee investments that attempt to reduce risks to people, property, and state interests in the Delta (Water Code section 85305) and recommend priorities for state investment in levee operation, maintenance, and improvements in the Delta (Water Code section 85306). In addition, the Delta Plan may identify actions to be taken outside of the Delta, if those actions are determined to significantly reduce flood risks in the Delta and may include local plans of flood protection (Water Code section 85307(a-b)). This paper outlines 15 issues that will need to be considered as the Council updates the Delta Plan’s provisions regarding State investment in the Delta’s levees. It summarizes background information about these issues, provides references for further information, and highlights key points to be addressed through the development of the Delta Levees Investment Strategy.
