of central California1990s: State water project, including the Kern Water Bank (pumps, wells, pipelines to recharge the aquifer during wet periods, then draw during dry)1995: State turned it over to Kern county, who sold 80% to private companies (farmers)Want to build a city between LA and Bakersfield using the water from the Kern Water BankTrying to get the water back to CAOwens Valley and Mono LakeOwens: Dry valley, in the Sierra Nevada rain shadowMulholland: Sold water rights in the whole countyBought the San Fernando Valley and made it part of LA so they could pass the bond measure and create the LA aqueductLA Times editors were sneaky and knew the plan, so bough San Fernando houses for pennies then sold for tons of money when water came inTook water that is fed into Mono Lake and put it into the aqueduct1980s: College students prove that Mono Lake’s levels were lowering because of water diversion to LAImportant stopping ground for birdsAlkaline lake fed by springs (Ca and Mg) and streamsSalinity increasing brine shrimp/flies which are base of entire food webCurrently, Owens Valley has no lake alkaline dust diseases, asthma, terrible air qualityLA owes debt to Owens Valley90% done, but have not looked into different mitigation except covering the dust with waterTo what extent is the DWP responsible?600+ million gallons of TREATED water discharged into SoCal oceans/dayRain water designed to go immediately off the streets the oceanSolutions:Rain water collection1 in of rain provides 600 gallons of H2O on a 100 sq ft houseBanned by CO, UT, and WALA is beginning to require rainwater captureTanks built into the walls, groundsRain water barrelsBiowalls: all drains into a low-lying areaLA Aqueduct: only gravity-fed aqueduct in CAAll others require energy (lots) to move it up and over mts, etcIs Southern California in a water crisis?Overproportioned the CO River to each state because when took the proportions, measured during wet years (even the last 100 years have been wetter)PLUS must deliver water to Mexico bc CO R. no longer reaches Gulf of CA in BajaWater too salty to give to Mexico, so made a desal plant at the border in AZ to barely make the qualification standards for H2O given to MexicoWhere does water come from?Almost half: MWD from CO River42% = LA Aqueduct13% = groundwaterUse grey water from showers, toilets, washing machines irrigate, and already have phosphates/nitrates in it no fertilizers necessaryLA recognizes that using more wastewater is necessaryOC has reclamation facility 4x as large as LACompletely transparent with the public easily embracedOur water contains treated wastewater anywaysLas Vegas puts their treated waste water into Lake Mead LANo greater hormones, pathogens, or other risky
