Los Angeles Aqueduct

Los Angeles Aqueduct Supplies Have Been Reduced

• 1994 State Board dedicates 100 TAF to Mono Lake
• 2000s Dust mitigation dedicates 40 TAF to Owens
  Lake
• 2006 Lower Owens River restored, requiring 30
  TAF to River
• 2000s Groundwater pumping limited to minimize
  impacts

LAA delivers about half as much water as it did
prior to 1990

Great Strides In Recycled Water Use and
Groundwater Recovery

• Recycling 59 projects, 194 million

• New LRP Programs 13 proposed projects

• Groundwater Recovery 21 projects, 80 million

Additional Focus On Conservation and Ocean
Desalination

• Recycling 59 projects, 194 million

• New LRP Programs 13 proposed projects

• Groundwater Recovery 21 projects, 80 million

• Conservation 223 million

• Desalination 5 proposed projects

Near-Term Imported Water Reductions

Coming out of an 8-year drought

• Baseline Water Use Efficiency
• Water Supply Watch
• Water Supply Alert
• Water Supply Allocation

Fishery conflicts cause cutbacks 2nd year of
drought
33
Water Rates MustIncrease Over Time

• Current infrastructure is aging
• New infrastructure will be needed for imported
  and local supplies
• Metropolitans rates will increase by 19.7 in
  September of 2009
• Rates may need to increase by more than 21 in
  2011
• Increases are likely to encourage more
  conservation and local supply development

Slide 8
34
Regional Focus On Water Use Efficiency

• Public agencies and cities must lead the way
• Outdoor water use will be a major focus
• California Friendly landscapes
• Efficient public parks/facilities and city halls
  will send the right message
• Changes to retail rate structures to reflect the
  cost of additional water supplies

Water Supply StrategyTomorrows Reliability

• Maintain diverse resource options
• Increase conservation, recycling, and
  desalination
• Strengthen partnerships to develop and manage
  additional water supplies.
• Invest in water quality and infrastructure,
  including Delta improvements
• Link investments to energy, wastewater, storm
  water, and watershed management
• Maintain financial strength

Federal Plans To Move Moab Uranium Tailings Pile

• Originally scheduled for completion in 2 phases
• 1st Phase 2.5 million tons by 2012
• 2nd Phase Remaining 13.5 million tons by 2028
• March 31, 2009 - Secretary of Energy announces
  108 million of Federal stimulus funds for Moab
  tailings removal
• Additional 2 million tons (total 4.5 million)
  removed by 2011 during 1st phase
• Accelerates projected completion of tailings
  removal to 2025

Actions Have Been Taken To Reduce Financial
Impact To Consumers

• 70M budget reduction
• Deferred 240M in capital expenditures
• Reduced workforce size
• 33 positions in 2009/10
• 20 reduction in last 10 years
• Executive bonuses forgone
• Budget based on no COLAs for workforce
• Renegotiation of contracts given economy
