Ancient Eel Weirs of the Susquehanna River

Long before dams and modern fisheries, the Susquehanna River was home to an ingenious system of stone fishing traps built by Indigenous peoples to harvest migrating American eels. In this episode, we explore the mysterious V-shaped rock weirs that still lie hidden beneath the river’s surface—carefully engineered formations that funneled eels into traps, providing a reliable and protein-rich food source that could be smoked and stored through the winter.Some researchers believe these sophisticated stone structures may be thousands of years old, possibly predating even the Egyptian pyramids. Today, many of them remain submerged or forgotten, but archaeologists, students, and conservationists are rediscovering them through satellite imagery while working to restore the Susquehanna’s fragile ecosystem. It’s a story where archaeology, ecology, and river lore come together—revealing just how central the eel once was to life along the Susquehanna.Read more at UnchartedLancaster.com.Cover Art: Native Lands by Artist Carol Oldenburg, 2021 hightlighting eel harvesting on the Susquehanna River
