Webinar Series

Throughout the implementation of the San Juan Watershed Program, EPA, states, and tribes, have actively engaged other federal, state, tribal, non-profit, academic, and other partners to lead, inform, and support WIIN-funded activities. In collaboration with participating states and tribes, EPA launched a regular webinar series in 2021 to highlight research, monitoring, implementation, and outreach projects throughout the watershed and engage new and existing partners. Past webinar presentations and recordings (when available) are provided below. For more information on upcoming webinars, contact EPA.
