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!

Expanding FIRO – Screening Corps Reservoirs Nationally for Forecast-Informed Operations Potential
Presenter: Elissa Yeates, ERDC Coastal and Hydraulics Lab, Hydrologic Systems Branch
Sneak Peek: The U.S. Army Corps of Engineers (USACE) research and operations program Forecast-Informed Reservoir Operations (FIRO) seeks to add flexibility to dam release decisions where possible to improve outcomes across multiple objectives, including flood risk management, water supply availability, groundwater recharge, and environmental flows. This approach has demonstrated benefits during recent water years at pilot sites, expanding demand for FIRO assessments and implementation at more reservoirs. A nationwide screening process for FIRO is being applied across the USACE portfolio of reservoirs, assessing opportunities for benefit, barriers to implementation, and sufficiency of forecast skill by site. This presentation shares results of FIRO screening nationwide and in more detail across the southwest region and connects those results with MAR opportunities downstream of USACE dams.

Increasing Groundwater Recharge Capacity in Southern San Joaquin Municipal Utility District – A Case Study Highlighting Planning, Funding, Constructing and Operating Recharge Facilities Within the District
Presenters: Sam Schaefer, Bryan Thoreson, Nayeli Rodriguez, GEI Consultants
Sneak Peek: The Southern San Joaquin Municipal Utility District is expanding its groundwater recharge facilities to enhance its ability to use surface water for replenishing groundwater. Originally supported by the Central Valley Project and the Friant-Kern Canal, the District’s water supply has faced challenges due to reduced CVP reliability and changing delivery schedules. In response to the Sustainable Groundwater Management Act (SGMA) of 2014, the District aims to develop 1,000 acres of recharge facilities over several years. This presentation will cover the District’s progress, including completed recharge sites and plans to convert vineyard land into spreading basins.

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. The next Workshop date is March 28. 2025.

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.
This fall (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. To help us create an engaging and interactive event that meets our collective goals, we’d love to receive your input via this brief eight-question survey—it should take about five minutes to complete. We appreciate your time and insights!
We will meet as Network to review survey input and further shape the Forum agenda at the March 28, 2025 Virtual Network Workshop from 10am – 12pm. We hope you can join us!
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:
