1 Southern California Water Dialogue
July 28, 2010 The Colorado River: Helping Metropolitan Navigate Through a Water Supply Crisis Bill Hasencamp Manager, Colorado River Resources Metropolitan Water District of Southern California

2 Urban Southern California’s Water Supply (w/capacity)
LAKE SHASTA LOS ANGELES AQUEDUCTS (0.5 MAF) LAKE OROVILLE Bay-Delta COLORADO RIVER AQUEDUCT (1.25 MAF) Updated with values from the January 2003 Ag Expo slide. STATE WATER PROJECT (2.0 MAF) LOCAL 2.0 MAF METROPOLITAN WATER DISTRICT SERVICE AREA

3 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.

7 California’s 7-Party Agreement For Colorado River Water
4.4 CA Apport. San Luis Reservoir (SWP Carryover Storage): ,000 CRA: ,000 SWP: 1,408,000 Total: ,251,000 Surplus over 1.7 MAF demand ,000

8 California’s Plan to Reduce Colorado River Use
Reduce Agricultural Demand Fund Water Conservation Programs Land Fallowing Programs Keep Colorado River Aqueduct Full Full Surplus when Lake Mead > 1145’ (62% of cap.) Plan Allows “Boom Years” to Continue

9 Colorado River Aqueduct Supplies

The various transfers will scale up during the 15 year period of the Interim Surplus Guidelines and will be fully in place at the end of this period.

20 Challenges Facing Colorado River

24 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.

25 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.

26 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

27 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.

38 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

39 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
