Newtown Creek is a tidal estuary located between the boroughs of Brooklyn and Queens in New York City. It flows into the East River and serves as a natural boundary between the two boroughs. The creek is approximately 3.5 miles long and has a rich history, having been an important industrial waterway since the 19th century. The area surrounding Newtown Creek has been heavily industrialized, leading to significant environmental challenges. Efforts are ongoing to clean up the creek and restore its ecosystem, as it has been affected by pollution from nearby factories and sewage overflows. The creek is also home to various wildlife, including fish and birds, making it an important habitat in the urban landscape.
