Project Description:

The 2021 Emergency Drought Salinity Barrier Project consists of constructing a temporary rock barrier across West False River in the Sacramento-San Joaquin Delta. The California Department of Water Resources (DWR) has determined that a salinity barrier is needed in response to the current drought conditions in the State of California. The West False River barrier is a temporary rock barrier to reduce the intrusion of high salinity water into the central and south Delta. On May 10, 2021, Governor Gavin Newsom declared a State of Emergency in 41 counties due to severe drought conditions. Under the proclamation, it states that: “the Department of Water Resources shall take actions, if necessary, to implement plans that address potential Delta salinity issues. Such actions may include, among other things, the installation and removal of, Emergency Drought Salinity Barriers at locations within the Sacramento-San Joaquin Delta.” DWR is requesting emergency authorization under the United States Army Corps of Engineers’ Regional General Permit 8 for the 2021 Emergency Drought Salinity Barrier Project. See Related Documents below for a complete project description.
