Given the broad interest and need to better understand and plan for ecological drought in the Southeast, the U.S. Geological Survey's Southeast Climate Adaptation Science Center and the National Oceanic and Atmospheric Administration's National Integrated Drought Information System (NIDIS), in support of the Southeast Drought Early Warning System, convened a 2-day workshop in January 2025. This workshop brought together scientists and managers from diverse fields, to address drought and low-flow in the Southeast and its impacts to aquatic systems across the region.

Despite the water-rich nature of the southeastern U.S., extended and intense dry periods intermittently occur across the region leading to reduced soil moisture levels and surface water supplies. These drought periods affect the landscape at different scales, with agriculture experiencing impacts earlier than other sectors
