Delaware Estuary

The Delaware Estuary is a productive coastal area where the Delaware River meets the Atlantic Ocean, blending freshwater from the river with salty ocean water. Covering parts of New York, New Jersey, and Delaware, it supports diverse ecosystems, including wetlands, marshes, and tidal flats. This estuary provides critical habitat for many fish, bird, and shellfish species, and is important for commercial shipping, recreation, and water quality. Its health depends on maintaining clean water, protecting habitats, and managing human activities to sustain the environment and local economies.
