VENTURA RIVER WATERSHED

Water Resilience for a Changing Climate

About the Project

The Watershed Resilience Program was designed by the California Department of Water Resources to be the next evolution of the Integrated Regional Water Management Program. The goal of the program is to accelerate locally led watershed resilience planning and implementation. This program would expand coordination and emphasize integrated, multi-sector, and outcome-based planning, action, and monitoring in response to climate challenges. This program is being piloted in five different watersheds throughout the State, with the Ventura River Watershed serving as one of the five pilots. Ventura River Watershed: Water Resilience for a Changing Climate program is the name for the Ventura River Watershed pilot project. The Ventura County Resource Conservation District is the administrator of the project.

This Project will develop a watershed network and watershed resilience plan that assesses multi-factor climate vulnerabilities and evaluates regionally equitable adaptation and implementation strategies.  

 The program will build on previous regional planning efforts.

  • Holistically study, plan, and manage water from headwaters to groundwater to outflow, at a watershed scale.
  • Integrate and prioritize equity and inclusiveness.
  • Analyze climate vulnerabilities/risks and potential adaptations at the defined watershed scale.
  • Plan and collaborate across water supply, flood, groundwater, water quality, forest/fire, ecosystem, and land use sectors.
  • Develop and apply performance indicators and metrics to measure, track, and report on outcomes at the regional and statewide level.

Why Do We Need Resilient Watersheds?

 

Climate resilience in watersheds is the ability of a watershed to recover from and respond to extreme weather events, such as floods, droughts, and seasonal changes in hydrology. Resilient watersheds can continue to provide services like water supply, flood management, and ecosystem support even after a climate-related disaster.

California’s watersheds are currently experiencing major climate change challenges that will be magnified in the future. Improving and accelerating climate resilience planning and implementation at the watershed scale will improve water resilience where impacts are most acutely experienced.

Water resource planning is necessary to safeguard water supply and quality, food security, protect vulnerable populations from drought, flooding, and extreme heat, prepare for sea level rise, and protect critical natural and built environments.

The Ventura River Watershed

Square Miles
226
Miles Long
33.5

  At 226 square miles, the Ventura River watershed is the smallest of Ventura County’s three major watersheds. The watershed extends from its Matilija Creek headwaters in the steep Transverse Ranges of the Matilija Wilderness to the Pacific Ocean, 33.5-miles downstream. The beginning of the Ventura River itself is marked by the confluence of Matilija Creek with North Fork Matilija Creek, 16.2 miles from the Pacific Ocean. The river flows south along the western edge of the Ojai Valley; past the City of Ojai and the communities of Meiners Oaks, Mira Monte, Oak View, Casitas Springs, and through the edge of the City of Ventura.

In its final stretch, the river flows through the Ventura River estuary, and if the sandbar is breached, proceeds to the ocean. Along the river’s route it picks up water from tributaries, the most significant being San Antonio Creek.

About the Watershed Council

The Ventura River Watershed Council is a coordination group for watershed planning in the Ventura River Watershed. It is an open group with active participation by government agencies, water and sanitation districts, environmental and educational non-profits, agricultural organizations, community volunteer groups, as well as engineers, biologists, businesses and private citizens. To learn more about the Watershed Council visit venturawatershed.org.

The group meets on a bi-monthly basis. To be a part of the Council and receive email alerts for upcoming meetings please join the Ventura River Watershed Council Newsletter.

The Ventura River Watershed Council is serving as the Watershed Network in the Ventura River Watershed: Water Resilience for a Changing Climate project.

Goals

Manage Grant Agreement including compliance with grant requirements, and preparation and submission of supporting grant documents.

Identify and assess existing regional networks, evaluating participant engagement and contribution, inclusivity, and health of the networks. Include regional water management groups, groundwater sustainability agencies, regional climate collaboratives, regional flood management groups, environmental groups, regional forest and fire capacity program groups, and other relevant water and resource management groups. Identify and engage vulnerable communities, 1 California Tribes, and watershed participants not previously included in water-related decision-making and assess their capacity and interest in contributing to this process. 

 

Deliverables:  

 

  • Draft Existing Regional Network Assessment section that includes an assessment of existing regional networks and engagement efforts and identifies any gaps in engaging historically excluded communities. 

The Ventura River Watershed Council has been adopted as the Watershed Network for this project. At the October 2024 General Meeting for the Ventura River Watershed Council the members voted in favor of joining the project as the Watershed Network.

An assessment of the governance structure will take place over the course of the project.

This project is delineating our project area as the Ventura River Watershed, which includes all tributaries that feed into the Ventura River.

Work with the watershed network to develop problem statements and establish the watershed resilience vision and goals to guide the development of the Watershed Resilience Plan.  

 

Deliverables:  

  • Draft watershed-specific resilience problem statements  
  • Draft watershed-specific resilience vision and goals  

Compile existing climate vulnerability assessments for water-related sectors, identify critical historical weather-related events and their impacts, and document major regional climate drivers and trends. The documented climate drivers shall include descriptions of historical weather-related trends and events/impacts and projected changes in temperature, precipitation, sea level, floods, drought, wildfire, and other climate-driven processes that are relevant to the watershed. Describe key climate challenges and opportunities for increasing future resilience. Document all of this information in a watershed problems and challenges chapter.  

 

Deliverables:  

  • Draft Watershed Problems and Challenges chapter  

Conduct the following work to assess watershed vulnerabilities and risks for the delineated watershed area:  

  • Develop vulnerability metrics and thresholds for major water sectors and land uses such as water supply, groundwater, flood management, ecosystems, water quality, recreation, and hydropower, and additionally, for equity considerations.  
  • Prepare an updated historical watershed water budget using appropriate methods outlined in the  of the 2020 DWR Draft Handbook for Water Budget Development.  
  • Assess and organize existing modeling tools for water resources vulnerability, adjusting or developing new models as needed for quantitative vulnerability assessments. Modeling tools may include, but are not limited to, watershed hydrological, groundwater, river basin management, river hydraulic, water quality, ecological, and economic models.  
  • Conduct climate vulnerability and risk assessments, initially qualitative, exploring climate hazards, system sensitivity, adaptive capacity, and vulnerability. Followed by a quantitative assessment evaluating current and future system performance related to water resource and equity metrics for water sectors indicating high climate vulnerability.  
  • Prepare a comprehensive vulnerability and risk assessment report, detailing the approach, methods, and findings of the above work, to enhance understanding of climate risks and conditions influencing vulnerability in the watershed.  

 

Deliverables:  

  • Draft watershed water budget  
  • Draft Climate Vulnerability Assessment and Climate Risk Assessment chapters  

Conduct the following work to identify priority risk areas, develop and evaluate adaptation strategies, and recommend actions for improvement:  

  • Conduct a thorough review of vulnerability assessment findings to describe priority risk areas based on the level of risk, impacts to multiple resources, and vulnerability metrics.  
  • Develop watershed-specific adaptation strategies encompassing infrastructure, land and water management, regulatory and policy measures, and regional approaches. These strategies will undergo rigorous evaluation considering risk reduction, technical complexity, cost, regulatory and environmental impacts, social effects, and equity considerations.  
  • Utilize quantitative methods aligned with vulnerability assessment tools to demonstrate risk reduction potential for one or more adaptation strategies.  
  • Document a set of recommended adaptation strategies, inclusive of benefits and costs. The strategies should address all water resource sectors and also demonstrate how equity considerations are included.  

 

Deliverables:  

  • Draft Adaptation Strategies chapter  

Identify and develop an implementation plan for each of the adaptation strategies recommended in Task 8. This plan shall encompass the adaptation strategy, specific actions, responsible leads, supportive parties, schedule, and implementation costs, serving as a guiding framework for strategy implementation over time. Work within the watershed network to actively engage in building public support for recommended strategies. This shall include tasks such as creating concise, publicly available information and messaging on the importance of adaptation for watershed resilience; posting this information to the Grantee’s website and conducting targeted outreach. Implementation strategies shall be developed, reviewed, and approved in open and public forums.  

 

Deliverables:  

  • Draft Implementation Strategies chapter  
  • Copies of outreach materials  

dentify watershed-specific performance tracking indicators that serve as “vital signs” for tracking current watershed conditions. Document the data sources and methods associated with each indicator.
