Delta Conveyance Project, formerly known as California Water Fix and Eco Restore or the Bay Delta Conservation Plan, is a $20 billion [1] plan proposed by Governor Jerry Brown and the California Department of Water Resources to build a 36 foot (11 m) diameter tunnel to carry fresh water from the Sacramento River southward under the Sacramento-San Joaquin Delta to Bethany Reservoir for use by ...
California groundwater basins, subbasins, and hydrologic regions. The California Department of Water Resources recognizes 10 hydrologic regions and three additional drainage areas within the U.S. state of California. The hydrologic regions are further subdivided into 515 groundwater basins. [1]
A catchwater drain is a land drain, a ditch cut across the fall of the land, typically just above the level of low-lying, level ground such as The Fens of eastern England, where some land, tens of kilometres from the sea is at about sea level. Its purpose is to gather water draining from the higher, sloping ground before it reaches the flat ...
Catchwater drains may take the form of concrete canals, such as in Hong Kong, where there are many.Alternatively, they may take the form of a large concrete sheet, smothering a hill, and preventing rainfall from entering the rock strata, with a smaller channeling system for transport of the water to the storage tank - this latter system is in operation in Gibraltar.
Santa Ana water resource basin: The drainage into the Pacific Ocean from the San Gabriel River Basin boundary to the Moro Canyon drainage boundary near Laguna Beach, California. Los Angeles County, Orange County: 2,680 sq mi (6,900 km 2) HUC180202: 180703 Laguna–San Diego Coastal water resource basin
California Reclamation Districts are legal subdivisions within California's Central Valley that are responsible for managing and maintaining the levees, fresh water channels, or sloughs (pronounced slü), [1] canals, pumps, and other flood protection structures in the area. Each is run autonomously and is run by an elected board and funded with ...
Recycled/Non-potable Water Distribution. Tertiary and other non-potable water (Colorado River water) is sent from the treatment plants and is used for golf course and other green belt irrigation, conserving groundwater pumping. [4] Conservation. CVWD has a wide variety of conservation programs to promote both indoor and outdoor conservation.
The California state hydrologic regions and drainage areas are quite similar but not identical to the federal hydrologic unit system's California water resource region surface-water drainage basins. The California Department of Water Resources has detailed descriptions (online in PDF format, etc.) of each of the 515 state-recognized groundwater ...
