The problems
  Floods of 1861-1862 , approx 30-35 MAF in additional Central Valley runoff
    from 3 "Pineapple Express" storms in 3 weeks (runoff figure is an
    off-the-record guess by a hydrologist)
  Reliable, affordable irrigation supply
  Loss of the snow pack to global warming
  Flows for the salmon on the San Joaquin
  Flows to flush salt and contaminants from the Delta
  Reduced Delta pumping for the fish and the flows
  No peripheral canal
  Hetch Hetchy
  Supply for Los Angeles
  Supply for Arizona and Southern Nevada
  Endless squabbling and redundant expensive reports

  West Side Conveyance System:
    Raise Shasta, +2 MAF, run flood flows into the West Sice Conveyance System
    Intercept Clear Creek/Whiskeytown/Trinity exports
    Dams as part of the System on the forks of Cottonwood, Red Bank, Elder,
      and Thomes, +.5 ?
    Glenn Reservoir Complex, +9 to +12
