Overview of Presentation MWD’s Evolving View of Colorado River 1940s – 2002: The Boom Years 2003 – 2007: The Hard Landing 2008 – 2010: Responding to Crisis Current Challenges Facing the River Using Trust Fund monies, Needles would be responsible for: -constructing Stage 2 of the Project to increase Project capacity to 10,000 acre-feet per year, -conducting studies to forecast the future salinity of Project water and assessing potential solutions should the salinity be projected to exceed the threshold, -implementing a solution to reduce the salinity of Project water, or acquiring a less expensive alternative supply to replace Project water, and -defraying any incremental increase in operation, maintenance, replacement, and administration costs necessary to operate and maintain the solution to reduce salinity.

Challenges Facing Colorado River

QSA Lawsuit CA judge invalidated QSA Transfers will continue through appeals process Federal officials to honor federal agreements Using Trust Fund monies, Needles would be responsible for: -constructing Stage 2 of the Project to increase Project capacity to 10,000 acre-feet per year, -conducting studies to forecast the future salinity of Project water and assessing potential solutions should the salinity be projected to exceed the threshold, -implementing a solution to reduce the salinity of Project water, or acquiring a less expensive alternative supply to replace Project water, and -defraying any incremental increase in operation, maintenance, replacement, and administration costs necessary to operate and maintain the solution to reduce salinity.

Salton Sea at Center of QSA Lawsuit Using Trust Fund monies, Needles would be responsible for: -constructing Stage 2 of the Project to increase Project capacity to 10,000 acre-feet per year, -conducting studies to forecast the future salinity of Project water and assessing potential solutions should the salinity be projected to exceed the threshold, -implementing a solution to reduce the salinity of Project water, or acquiring a less expensive alternative supply to replace Project water, and -defraying any incremental increase in operation, maintenance, replacement, and administration costs necessary to operate and maintain the solution to reduce salinity.

Salton Sea Restoration/Mitigation Salton Sea becoming too salty for fish DWR’s preferred restoration alternative $ 9 Billon $200 million/yr QSA addressed mitigating transfer impacts

Binational Agreement on Shortages 2007 Guidelines for shortages only applied to United States Shortages to Mexico to be determined later Reclamation and States developing comprehensive binational proposal Using Trust Fund monies, Needles would be responsible for: -constructing Stage 2 of the Project to increase Project capacity to 10,000 acre-feet per year, -conducting studies to forecast the future salinity of Project water and assessing potential solutions should the salinity be projected to exceed the threshold, -implementing a solution to reduce the salinity of Project water, or acquiring a less expensive alternative supply to replace Project water, and -defraying any incremental increase in operation, maintenance, replacement, and administration costs necessary to operate and maintain the solution to reduce salinity.

Crisis in Mexico: April 5, 2010

Mexico and U.S. Discussing Short-term Agreement May allow Mexico to store water in U.S. Reservoirs May allow Mexico to sell water to U.S. to fund infrastructure repair May allow partnerships for new water management programs Attempting to reach agreement in next 90 days

Summary CA has adapted to living with less water in a way to meet the state’s needs Several challenges continue: Drought Climate Change Binational Issues States have a track record of working successfully together to confront issues
