Comparing Futures for the Sacramento - San Joaquin Delta

Jay Lund

Publication Year: 2010

An ecosystem in freefall, a shrinking water supply for cities and agriculture, an antiquated network of failure-prone levees—this is the Sacramento-San Joaquin Delta, the major hub of California's water system. Written by a team of independent water experts, this analysis of the latest data evaluates proposed solutions to the Delta's myriad problems. Through in-depth economic and ecological analysis, the authors find that the current policy of channeling water exports through the Delta is not sustainable for any interest. Employing a peripheral canal-conveying water around the Delta instead of through it—as part of a larger habitat and water management plan appears to be the best strategy to maintain both a high-quality water supply and at the same time improve conditions for native fish and wildlife. This important assessment includes integrated analysis of long term ecosystem and water management options and demonstrates how issues such as climate change and sustainability will shape the future.

The Sacramento–San Joaquin Delta is significantly changed from its historic condition. Before the arrival of Europeans, the Delta was one of California’s most dynamic landscapes. Lying at the confluence of the Sacramento and San Joaquin rivers and their floodplains at the head of the San Francisco Estuary, ...

pp. 57-68

Changes in the Delta are inevitable, given the unstoppable processes of sea-level rise, land subsidence, earthquakes, and a warming climate bringing larger floods. As discussed in Chapter 3, these changes pose grave questions about future land uses in many parts of the Delta. ...

Since water exports began in the 1940s, the Delta has been managed to keep its water fresh enough for agricultural and urban uses by export users and in- Delta users. This management—achieved through the release of water from upstream reservoirs and changes in export schedules—can vary daily because of the Delta’s complex and dynamic physical environment. ...
