Drought conditions have prompted the building of a 750-foot wide rock barrier to prevent saltwater intrusion into the Sacramento-San Joaquin River Delta. The California Department of Water Resources constructed the temporary barrier with 110,000 cubic yards of rock off West False River in Contra Costa County. Principal engineer Jacob McQuirk said that saltwater would endanger freshwater supplies in the Delta and water exports to the south without the barrier.
