Who We Are

The Flood-MAR Network is a vibrant collaboration of individuals and organizations dedicated to promoting Flood-MAR implementation in California.

Stay up-to-date with the latest Flood-MAR news and activities!

Coordinating Team

The Coordinating Team supports the Flood-MAR Network to ensure that the Network is effective in promoting the implementation of Flood-MAR projects throughout California. The Coordinating Team helps identify emerging and priority topics that should be brought to the Network for discussion and further action. Coordinating team members meet monthly, and team membership rotates annually.

Action Teams

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:

Estimating Recharge – seeks to identify best approaches for the practical estimation of aquifer recharge.
Incentives for Flood-MAR – expands information-sharing regarding existing and previous incentives programs and generates ideas for new incentives or strategies.
Water Quality Monitoring – identifies considerations for managing or mitigating contaminants under flooded conditions, and compiles data to support agencies in developing best practices, guidance, and models for Flood-MAR.
Instream Flows - considers how to balance water used for recharge and instream ecological needs during Flood-MAR project operations.
Assessing Policy – explores ways to further leverage opportunities and/or address barriers to effective State support and coordination.
Website – manages content and maintains updates to the floodmar.org website. The Flood-MAR website was formally released to the public October 10th, 2023 (read the Flood-MAR HUB press release here).

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!

To join or be added to an Action Team email roster and learn of upcoming meetings and efforts, please drop us a note at floodmar.network@gmail.com.

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

Check out the full Agenda here.
Review the meeting Slide Deck here.
Watch the full recording here.

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:

Showcase recent impactful work from Network Members
Advance collaborative initiatives to for Flood-MAR implementation in California
Encourage active participation in the Network’s activities
Engage members in the planning of the 2025 Biannual Network Form

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

Thank you to everyone who joined us November 5–6, 2025 for two incredible days of connection, learning, and momentum-building. The energy was off the charts! We couldn’t have done it without ALL OF YOU!!

Want to relive the highlights? Our friends at Sustainable Conservation put together a fantastic recap capturing the ideas, inspiration, and big takeaways. Check it out here: “From Concept to Practice: Reflections on the 2025 Flood-MAR Network Forum.”

And a HUGE THANKS to this year’s amazing sponsors who help keep the Network thriving and make this biannual event possible!

2023 Flood-MAR Forum | Flood-MAR in Action

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.

Read the short summary document which synthesizes highlights of the event here.
Watch recordings of the many excellent presentations and discussions from the event by clicking the links in the event agenda below.

From this sharing of experiences and ideas, Forum discussions culminated in five main takeaways:

California is poised to scale up Flood-MAR as a significant strategy for addressing groundwater overdraft, but more work is needed.
Partnerships and collaboration among growers and water managers have been key to successful Flood-MAR.
Flood-MAR lends itself to multiple benefits beyond groundwater recharge and flood protection.
State support and coordination across agencies helps streamline and activate Flood-MAR.
Flood-MAR projects are a good investment for California.

"For me, [Flood-MAR] is the solution that provides the hope. That proves the solutions are on our land, if we work together, and are willing to take an integrated resource management approach and think about all the multi-benefits."
