Legacy Sediment

Have you ever wondered what happens to sediment once dams are removed? Scientists from Boston College and Franklin and Marshall are studying the effects. They’ve discovered that sediment once ponded by a dam in Lancaster County, PA traveled all the way to the Chesapeake Bay! This sediment transport effects nutrient availability and river morphology.
