Lower Basin Drought Contingency Plan Current Concepts

  • The Upper Basin States and Lower Basin States have each

undertaken actions to guard against potential adverse consequences associated with critically dry conditions.

  • The goal of the ongoing discussions is to develop additional tools

for the Lower Basin States to utilize through at least December 31, 2025, to address potentially critical elevation declines in Lake Mead.

  • Any new agreement would further the implementation of the

2007 Interim Guidelines.

SLIDE 10

Elements of Lower Basin Drought Contingency Plan – Current Concepts

  • Avoid and protect against the potential for the elevation of Lake Mead

to decline to elevations below 1,020 feet Reductions of water use beyond the level of reductions required by the 2007 Interim Guidelines

  • Includes a commitment by the U.S. to work to create or conserve

Colorado River system water

  • Recovery of additional reduction volumes would be allowed under

certain conditions

  • Incentivize ICS creation/storage
  • Agree that ICS may be withdrawn at lower Lake Mead elevations, similar

to ICMA arrangements under Minute 319

  • Modification of the evaporative losses currently applied to ICS

First track:

  • Prioritize and evaluate all of the 22 Planning Areas identified in

the Strategic Vision

  • ADWR will work closely with 22 Planning Areas individually to

refine water supply and demand issues and identify strategies to meet future water demands

  • Goal is to develop stakeholder driven set of solutions for future

water demand and supply imbalances

  • Goal is to complete the process within a Planning Area within 1

year

Governor’s Water Initiative First Track – Planning Area Process

SLIDE 19

Second track:

  • Goal is to investigate long-term augmentation strategies,

explore additional water conservation opportunities and identify infrastructure needs.

  • Members appointed by the Governor to represent water

resource experts, industry leaders, NGOs, local government, watershed groups

  • ADWR Director serves as chairman
  • Council will report back to the Governor with policy direction
  • r statutory changes
  • ADWR provides staffing and technical assistance
  • Annual progress report will be due July 1st

Governor’s Water Augmentation Council – 2016 Annual Report

  • Included recommendations in 3 categories:
  • General tenets: Council to provide guidance to the Director of

ADWR, continued implementation of water conservation, identify augmentation opportunities to resolve water conflict

  • ADWR actions: continue to lead AZ water conservation efforts,

assess the need for additional conservation through Planning Area process, explore reduction of Lost & Unaccounted for

  • utside of Active Management Areas
  • Topics of focus: development of communications plan,

augmentation through reuse of reclaimed and poor quality water, funding, potential for augmentation through natural and constructed recharge, and large scale augmentation opportunities

Sub-Committees

  • Goal: Investigate desalination opportunities to

augment the State’s water supplies. Desalination: Bob Lotts, Chairman

  • Goal: Funding and financing strategies for

water supply augmentation and infrastructure needs for the State. Finance: Rick Lavis, Chairman
