The East River is a tidal strait that flows between the boroughs of Manhattan and the Bronx in New York City. It is approximately 16 miles long and is one of the five boroughs' waterways. Historically, the East River was a busy and important shipping channel and played a significant role in the city's growth and development. Today, it serves as a critical source of water for the city, with numerous reservoirs and dams along its course. These include the Kensico Reservoir, which stores water from the Catskill Mountains, and the Ashokan Reservoir, which provides water to the city's residents. The river also offers a range of recreational activities, including fishing, boating, and kayaking. Agricultural use along the East River is limited due to its urban location.
