Rivers and Waterways in Delaware
Delaware’s river system is relatively small but vital, shaped by its flat coastal plains and proximity to the Atlantic Ocean. Most rivers flow eastward into Delaware Bay or directly into the Atlantic, while the northern part of the state connects to the Delaware River system. Slow-moving rivers and tidal waterways are common, especially in southern areas. Delaware also relies on a few reservoirs and ponds that support drinking water, agriculture, and local ecosystems across the state.
