Monday Top of the Scroll: Drought is pushing more saltwater into the Sacramento-San Joaquin River Delta. California built a wall to keep it out
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 without the barrier, saltwater would endanger freshwater supplies in the Delta and water exports to the south. … McQuirk said 27 million people are dependent upon those water supplies and that the barrier will be taken down by November.
