Action Teams are collaborations of volunteer Flood-MAR Network members who seek to identify and advance a particular product, project, or initiative over the next one to two years. The six Action Teams emerged from discussions during the March 2023 quarterly Flood-MAR Network workshop, demonstrating a desire to leverage the collective resources of the Network, turn ideas into tangible outputs to benefit the Flood-MAR community, and ultimately advance Flood-MAR statewide.
The Action Teams are:
We invite you learn more and consider joining an upcoming meeting if your work (or your curiosity) intersects with the goals of an Action Team. Our work is improved when our expertise and experience are shared!

Removal of Suspended Solids and Water Quality Improvements from Riverbed Filtration-Eight Years of Demonstration Testing in Orange County, CA
Presenter: Adam Hutchinson, Orange County Water District
Sneak Peek: Clogging of surface water recharge systems from suspended solids is a major obstacle to effective groundwater recharge—but what if there were a better way? Join us to learn how the Orange County Water District’s innovative Riverbed Filtration System more than doubled recharge capacity while removing 96% of suspended solids from Santa Ana River water. Discover how this breakthrough could unlock thousands of acre-feet of additional recharge annually and transform the future of water management.

Regenerative Agriculture, Water and Nitrogen in the California Central Valley
Presenter: Daniel Rath, Natural Resources Defense Council
Sneak Peek: What does California’s new definition of regenerative agriculture mean for water quality and recharge efforts?This session explores how the state’s landmark move to define regenerative agriculture could influence groundwater programs—especially efforts to manage nitrate contamination. Learn how Managed Aquifer Recharge (MAR) may support both soil health and cleaner water when paired with smart nitrogen strategies.

An Overview of the Groundwater Accounting Platform
Presenter: California Water Data Consortium
Sneak Peek: The Groundwater Accounting Platform is an open-source tool that helps California water managers, landowners, and water users track water budgets and usage more easily in near real-time. The California Water Data Consortium and Environmental Defense Fund have partnered to expand the Platform to new regions, and to provide additional features and functionalities to help more groundwater agencies and growers track water use allocations under SGMA. Come and learn more about new updates to the tool and a vision for the future on August 6, 2025
LATER 2025 SESSIONS:
Virtual Flood-MAR Network Workshops
All Flood-MAR Network members are invited to attend periodic virtual workshops. These workshops provide opportunities for members to engage in conversations and collaborate on Flood-MAR projects.
Latest Network Workshop: Friday March 28 from 10 am – 12 pm
This virtual workshop aimed to reflect on the progress made in 2024, re-energize our collective efforts, and collaboratively shape priorities for 2025. Key objectives were:
FIRO-MAR Learning Group
The FIRO-MAR learning group is dedicated to sharing information on the latest advancements in linking forecast-informed reservoir operations (FIRO) with Flood-MAR. This group is on a short break and will reconvene in 2025.
Biennial Forums
Flood-MAR forums have been held biannually since 2017 to discuss and address the opportunities and challenges of implementing flood-MAR in California.
2025 Flood-MAR Forum | Grounded in Success, Growing Towards the Future
On November 5 & 6, 2025, we’re excited to host the next Flood-MAR Forum, a biennial event dedicated to exploring opportunities and challenges in implementing Flood-MAR in California. Save the Date! More information and event website coming soon!
The Flood-MAR Network hosted its fourth biennual Flood-MAR Public Forum on November 7 & 8, 2023, at the CSUS Harper Alumni Center in Sacramento. Nearly 100 Flood-MAR practitioners gathered to share success stories and lessons learned from the landmark wet winter of 2022 – 2023 and identify areas for further preparation needed to implement projects that use floodwaters for managed aquifer recharge in future wet years, for the benefit of communities, ecosystems, and agriculture.
From this sharing of experiences and ideas, Forum discussions culminated in five main takeaways:
