Flood-MAR Network

California's Living
Flood-MAR Collaboration Hub

Welcome to the Flood-MAR Hub!


Flood-MAR (Flood-Managed Aquifer Recharge) uses excess water from high-flow events to replenish groundwater supplies by directing it onto suitable agricultural lands, working landscapes, and managed natural areas where it can safely infiltrate into aquifers.

This innovative approach can help California reduce flood risk, improve water supply reliability, support ecosystems and agriculture, and build resilience to climate change. Because these benefits span communities, landscapes, and sectors, advancing Flood-MAR requires strong partnerships and collaboration across California.

That's where the Flood-MAR Network comes in: connecting people, sharing knowledge, and accelerating the partnerships needed to advance Flood-MAR across the state.

Recharge Readiness | “Rapid” Groundwater Recharge Assessment Tool Options

Thursday September 10, 2026, 11:00 a.m. - 12:00 p.m.

The webinar series will continue the discussion about tools that can support recharge planning. Two expedited, district-scale applications of the Groundwater Recharge Assessment Tools (GRAT) will be presented, and how other districts could use these tools. 

Presenters: Roshni Katrak-Adefowora, Sustainable Conservation; Kristin Sicke, Yolo County Flood Control & Water Conservation District; and Daniel Siegel, Earth Genome


Flood-MAR Network Virtual Workshop: A New Era of California Water Planning

Thursday September 17, 2026, 10:00 a.m. - 12:00 p.m.

Join the Flood-MAR Network for a virtual workshop to learn about current planning and implementation efforts underway by the State of California to expand recharge – with a special focus on California Water Plan 2028 – and to take part in discussion with Network members on ways to get involved.


Recharge Readiness | On Farm Recharge Guidance for Practitioners

Thursday September 24, 2026, 11:00 a.m. - 12:30 p.m. *90 mins

Growers are essential partners in expanding groundwater recharge—and successful implementation of local groundwater sustainability plans will depend on making on-farm recharge practical, effective, and workable in the field.
 
Join us for a special 90-minute Recharge Readiness session focused on the nuts and bolts of on-farm recharge. Hear about the experience of growers implementing on-farm recharge projects including what they’ve learned about field preparation, recharge methods, crop considerations, and implementation on a variety of crop types. And, explore practical resources to help growers implement on-farm recharge.
 

Presenters: Rogell Rogers, Wendy Rash, and Roshni Katrak-Adefowora of Sustainable Conservation; Matthew Watte, pistachio growe


Lunch-MAR | October 7

Economics of Managed Aquifer Recharge

What is managed aquifer recharge really worth? Join us as we explore the economics of MAR, from the costs and benefits identified across the research literature to new insights from the Kern Water Bank. This session will preview a forthcoming synthesis report and present an empirical case study using agricultural land values to estimate the economic value of groundwater storage and banking for landowners.

Presenter: Ellen Bruno, UC Berkeley

Wednesday, October 7, 2026, 12:30PM -1:30PM PT
