Purpose: To identify viable strategies to guide Arizona in addressing future water needs, providing a stable economy for our future – for all water users. ‐ Use existing information (CRBS, WRDC, Az. Water Atlas, Water Level Monitoring, AMA Assessments…)‐ Identify Local Options First‐ Identify Priority Strategies
Arizona Strategic Vision for Water Supply Sustainability
Salt River Project Colorado River Compact & Law of the River Central Arizona Project Resolution of Tribal Water Rights Claims 1980 Groundwater Management Act
‐ National leader in water conservation and water reuse programs within the five Active Management Areas
Assured and Adequate Water Supply Program Recharge and Recovery and Arizona Water Banking Authority
‐ 8.5 million acre‐feet in storage for future use
Building on Historic Accomplishments
Water Supply Opportunities Non‐Indian Agricultural (NIA) Priority CAP water; Reclaimed water/water reuse; Groundwater in storage (potable, poor quality & brackish supplies); Water supplies developed from revised watershed management practices; Water supplies developed through weather modification; Water supplies developed from large‐scale or macro rainwater
harvesting/stormwater capture; and Importation or exchange of new water supplies developed outside of
Arizona (e.g., ocean desalination)
Identifying Opportunities and Challenges
Challenges Complex Physical Water Supply Availability Land Ownership
69% of Lands in Arizona Federally Owned & Managed Access to Water Supplies and Transmission of Future Water Supplies Federal Reserve Rights NEPA/ESA/CWA Compliance
General Stream Adjudication Outstanding Tribal Water Rights Claims Complex Water Rights System
Identifying Opportunities and Challenges
Water Resources Development Commission (WRDC ‐ 2010) Assessed water demand and available supplies for the next 25, 50 and
100 years (2035, 2060 and 2110). Total statewide demand between 8.1 MAF in 2035 and 10.6 MAF in 2110
(current demands 6.9 MAF) Imbalance between 900,000 AF and 3.2 MAF
Colorado River Basin Water Supply & Demand Study (Basin Study) 2060 Colorado River Basin‐Wide Average Imbalance 3.2 MAF 2060 Arizona Imbalance between 242,900 to 1,269,700 acre‐feet
WRDC concluded that without proactive and localized water management strategies future water supply and demand imbalances may exist throughout the state, and, therefore, there is a need to acquire additional water supplies and develop infrastructure to access new and existing unused water supplies
Identification & Analysis of Supply/Demand Imbalances
Regional Strategies‐ Identification & Analysis of “Planning Areas”
Statewide Priorities‐ Common Strategies Across the State
Action Plan‐ What’s Next??
Resolution of Federal and Non‐Federal Water Rights Claims‐ General Stream Adjudication‐ Indian Water Rights Settlements
Continued Commitment to Water Conservation & Reuse of Reclaimed Water – Including Direct Potable Reuse
Comprehensive Statewide Data Collection & Analysis (Modeling Local Conditions)
Identify the Role of In‐State Water Transfers Supply Importation ‐ Desalination Funding
‐ Business leaders, Community and State leaders‐ Rural Infrastructure
Strategic Priorities For Moving Arizona Forward
Legislate Strategic Vision update every 10 years (Year 1) Begin Discussions on Ocean Desalination (Year 1)
‐ Exchange Options (California & Mexico )
‐ Direct Delivery Options (Mexico)
Resolve ADOT Right‐of‐Way Issues for Utilities (Year 1) Establish Adjudication Study Committee (Year 1)
Begin Discussions on Water Development Financing (Year 2) ‐ Immediate Needs for Water Resources Development Revolving Fund for rural Arizona‐ Long‐Term Needs for Large‐Scale water importation projects
Remove statutory limitation (A.R.S. § 45‐801.01(22)) on the ability to receive long‐term storage credits for recharging reclaimed water beyond 2024 (Year 2)
Ten Year Action Plan
Review and implementation of Adjudication Study Committee Findings (Year 3)
Review Legal and Institutional Barriers to Direct Potable Reuse of Reclaimed Water – develop and implement plan for resolution (Year 3)
Develop and Begin Implementation of Direct Potable Reuse of Reclaimed Water Public Perception Campaign (Year 4)
Begin discussions with New Mexico on an Interstate Cooperative Program for Watershed Management/Weather Modification in the Upper Gila Watershed (Year 4)
Resolve Remaining Indian Settlements (Year 1 ‐ 10) Resolve General stream Adjudication (Year 5 ‐ 10)
Ten Year Action Plan (cont.)
State of Arizona is not facing an immediate water crisis Some local areas require more immediate action
Growing statewide imbalance between water supplies and demand projected in the next 25 years
Lack of an immediate problem increases the potential for inaction, running the risk of procrastinating and not motivating ourselves to plan and invest in our future
Arizona’s future success is tethered to how well we continue to manage our water resources and develop new water supplies and infrastructure
Arizona needs a continuing Strategic Vision for Water Supply Sustainability to guide its economic stability through the next century

Study Requirements Each Basin Study will include four elements:
1. Projections of water supply and demand, including an assessment of risks to the water supply relating to climate change.
2. Analysis of how existing water and power infrastructure and operations will perform in the face of changing water realities, such as population growth and climate change.
3. Development of options to improve operations and infrastructure to supply adequate water in the future.
4. A trade-off analysis of the options identified, findings and recommendations as appropriate.
West Salt River Valley Basin Study Will Include:
• Updated Supply and Demand Study
• Climate Change Analysis
• Updated Ground Water Modeling
• Updated Economics Modeling
• Trade‐off Analysis and Recommendations

Interim Guidelines (2007)• Basin States agreement in 2006 for
conjunctive management of Lakes Powell and Mead and shortage sharing in the Lower Basin
• Adopted by Secretary in 2007
• Effective through water year 2026
• Renegotiation to start by 2020
77
2007 Guidelines• Lower Basin apportionments are reduced when
Lake Mead falls below specified elevations:
Elevation Reduction1075’ 333,000 AF1050’ 417,000 AF1025’ 500,000 AF
• If Lake Mead is projected to fall below elevation 1000, the Secretary will consult with Basin States to discuss further measures
78
Shortage Sharing• Arizona and Nevada share Lower Basin
shortages under the 2007 Guidelines• Mexico voluntarily agreed in Minute 319 to
accept reductions in its deliveries at the same elevations

“Bending the Curve”
• Requires significantly reducing or eliminating the structural deficit in the Lower Basin
• Benefits accrue to both Upper and Lower Basins
• Ultimately, there are only three ways to slow the decline of Upper and Lower Basin reservoirs:- Reduce system losses
- Reduce demand
- Augment supply
