🗺️The U.S. Drought Monitor released this morning shows stronger drought conditions spreading further east since last week’s map. The data is valid through last Tuesday, so it doesn’t include the recent rain.
That’s a Wrap on the 2025 Potomac River Conference
The 2025 Potomac River Conference: Integrating Science, Policy & Management to Combat Harmful Algal Blooms was held on October 22, 2025, at the George Mason University Potomac Environmental Research and Education Center (PEREC) in Woodbridge, Virginia.
ICPRB’s annual conferences highlight important issues facing the Potomac River watershed. Previous topics included PFAS and invasive species.
The most recent conference, organized and hosted by the Interstate Commission on the Potomac River Basin (ICPRB), focused on research and management of harmful algal blooms (HABs) in the Potomac River basin and beyond. The event opened with remarks from ICPRB and PEREC leaders, followed by three main sessions highlighting research, local, and government responses to HABs. Session 1 presented scientific studies on cyanobacteria ecology, toxin production, and environmental drivers. Session 2 explored local monitoring, response strategies, and societal impacts, including the use of remote sensing and community management practices. Session 3 featured a government panel discussing multi-state coordination and detection of algal toxins, complemented by a poster session showcasing emerging research and management innovations.
