Rivers, lakes & waterways

Alexandria's identity is inextricably linked to the **Potomac River**, which forms the city's eastern border. The river served as the foundational trade route that established Alexandria as a colonial seaport and today provides scenic beauty and maritime recreation. Additional significant local waterways include **Four Mile Run**, a large tributary stream that separates Alexandria from Arlington County, and **Hunting Creek** to the south, a tidal inlet noted for its wetlands and bird habitats.
