Integrated Water Management is Part of the Solution
Integrated Water Resources Management Definition (Global)
A process which promotes the coordinated development and management of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems - Global Water Partnership (GWP)
![Page 13: Sustainable water management: How do we get there?](https://reader036.vdocuments.net/reader036/viewer/2022081511/568162be550346895dd34aa1/html5/thumbnails/13.jpg)
Integrated Water Management is Part of the Solution
Integrated Water Management Definition (California)
Comprehensive and collaborative approach for managing water to concurrently achieve social, environmental, and economic objectives. In the California Water Plan, these objectives are focused toward improving public safety, fostering environmental stewardship, and supporting economic stability. IWM delivers higher value for investments by considering all interests, providing multiple benefits, and working across jurisdictional boundaries at the appropriate geographic scale. – CA DWR, Calif Water Plan Update 2013

Defining “Sustainable Water Management”
Recent CA Legislative Proposals for Groundwater: Senate Bill 1168
Management of a groundwater basin to provide for multiple long-term benefits without resulting in or aggravating conditions that cause significant economic, social, or environmental impacts such as long-term overdraft, land subsidence, ecosystem degradation, depletions from surface water bodies, and water quality degradation, in order to protect the resource for present and future generations.
Assembly Bill 1739 Management and use of groundwater in a manner that can be maintained
during the planning and implementation horizon without causing unreasonable adverse environmental, economic, or social consequences through the development, implementation, and updating of plans and programs based on the best available science, monitoring, forecasting, and use of technological resources, as determined by a groundwater sustainability agency.

Return on State InvestmentsIRWM Implementation Projects
48 Regional Groups; 87% population
425 projects funded statewide
$577 Million in State grant investments
Leveraged by $2.85 Billion in local (non-State) cost match(Prop 50, Round 1
& 2 Prop 84, Round 1)

Stakeholder Feedback Confirms Value of the Integrated Regional Approach
“The greatest valueof IRWM is creating more collaboration,
integration and extra money to make
projects succeed”
“…promoting a better understanding of each
others’ issues”
“Since its beginning, there has been a
huge difference in the working relationships among stakeholders”
“Promoted cross-boundary,
multi-benefit projects”
“Supported smaller projects that
wouldn’t have happened otherwise”
“More towards watershed-wide water resources
planning”
We’ve made good progress on collaboration…now onto improved cooperation and compromise

California Water Action Plan
Ten Priority Actions/Objectives:1. Make conservation a California way of life2. Increase regional self-reliance and integrated water management across all levels of government3. Achieve the co-equal goals for the Delta4. Protect and restore important ecosystems 5. Manage and prepare for dry periods 6. Expand water storage capacity and improve groundwater management 7. Provide safe water for all communities; 8. Increase flood protection; 9. Increase operational and regulatory efficiency; 10. Identify sustainable and integrated financing opportunities.

Future Financing Strategies Need more reliable, predictable diverse
mix of finance mechanisms and funding sources to invest in actions with broad public benefits
Desired attributes: Avoid stranded cost, funding
discontinuity Leverage funding across government
agencies Improve cost effectiveness, efficiency,
accountability Increase certainty of outcomes
