This Flood-MAR Research and Data Development Plan (R&DD Plan) presents the work of the Flood-MAR Research Advisory Committee (RAC), a multidisciplinary group of subject matter experts across 13 research themes. The RAC was tasked to identify the research, data, guidance, and tools necessary to support and expand the implementation of Flood-MAR projects.
This technical memorandum provides guidance for developing and expanding on-farm groundwater recharge programs using the Yolo County Flood Control & Water Conservation District as a case study. It presents a practical field prioritization methodology, summarizes implementation lessons from the 2025–2026 recharge season, and offers recommendations for grower outreach, incentives, and future recharge planning.
Introduces RapidGRAT, a streamlined tool for rapidly estimating managed aquifer recharge potential at the basin scale. Using the Greater Kaweah Subbasin as a case study, this technical memorandum describes a scalable methodology that combines land use, soil suitability, crop compatibility, and conveyance capacity to identify recharge opportunities and support groundwater sustainability planning, infrastructure investments, and funding applications.
