OWOW 2.0 Plan
Moving into Implementation
On February 19, 2019, the SAWPA Commission officially adopted the One Water One Watershed (OWOW) Plan Update 2018, the Integrated Regional Water Management (IRWM) Plan for the Santa Ana River Watershed. This plan represents the culmination of the work of over 100 authors from water agencies, non-profits and other stakeholders in the watershed who worked together to analyze, develop and describe new integrated implementation actions needed to address the water challenges facing the watershed. The Plan reflects a collaborative planning process that addresses all aspects of water resources in the Santa Ana River Watershed. It includes planning of future water demands and supplies over a 20-year time horizon within the watershed as a hydrologic and interconnected system.
OWOW Program Vision is a watershed that:
- Is sustainable, droughtproof, and salt balanced by 2040
- Avoids and removes interruptions to natural hydrology, protecting water resources for all
- Uses water efficiently, supporting economic and environmental vitality
- Is adapted to acute and chronic climate risk and reduces carbon emissions
- Works to diminish environmental injustices
- Encourages a watershed ethic at the institutional and personal level
Review Period
The draft Plan was completed on September 30, 2013, posted on the SAWPA website and opened for public comment thereafter. On January 16, 2014, the One Water One Watershed Steering Committee received public comments, responses, and voted to recommend the Plan for adoption to the SAWPA Commission. View response summary
