The Sassafras River rises in western Delaware and flows westerly to the Chesapeake Bay, forming the natural boundary between Cecil and Kent Counties, Maryland. The Sassafras is tidal for the great majority of its approximately 20-mile length and is fresh to slightly brackish. The watershed comprises an area of 75.5 square miles of land.

As the Sassafras Riverkeeper, Zack is the primary spokesperson for the Sassafras River and uses advocacy, outreach, restoration, and education to be a voice for the river, its natural resources, and its inhabitants. He is a vigilant, on-the-water presence working with local communities to achieve a healthier Sassafras, tackling issues including the Conowingo Dam, invasive water chestnuts, and harmful algal blooms using science-based solutions. A native Marylander, Kelleher’s conservation ethic and love of the Chesapeake Bay comes from the time he spent growing up outside of Tilghman Island. There, he learned to appreciate the rich cultural heritage and the immense beauty of the Eastern Shore while hunting, fishing, and crabbing on Harris Creek and the Choptank and Miles Rivers. Kelleher graduated from the University of Maryland with degrees in Psychology and Sustainability. Previously the Restoration and Outreach Manager, Kelleher is excited to continue furthering ShoreRivers’ mission of protecting and restoring Eastern Shore waterways while serving as the voice of the Sassafras.
