Friends of the Lower Olentangy Watershed (FLOW) is a volunteer-based nonprofit established in 1997 with a mission to keep the Olentangy River and its tributaries clean and safe for all to enjoy, through public education, volunteer activities, and coordination with local decision-makers. Your donation helps us continue our conservation work, including tree plantings, invasive species removal, stream quality monitoring by citizen scientists, pollinator garden planting/maintenance, and litter cleanup efforts.
