How to read this map
The Delaware River is about 579 km (360 mi) long and drains a basin of about 36,600 km² (14,100 sq mi). Its average discharge is about 224 m³/s (7,910 cu ft/s). It flows into the Delaware Bay. It flows through or along New York, New Jersey, Pennsylvania and Delaware. Tributaries include Neversink River, Schuylkill River, Assunpink Creek, Lehigh River, Big Bushkill Creek, Crum Creek, Darby Creek and East Branch Delaware River.
The highlighted blue line is the course of the Delaware River as mapped by Natural Earth. Towns and cities on the map include New York City, Philadelphia, Baltimore, Bridgeport, Albany, Stamford, Syracuse and Harrisburg. Labeled states and countries: New York, Maryland, New Jersey and Connecticut.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders, and fine dashed lines show state or province borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the course of the Delaware River come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the line is a guide to where the Delaware River is, not a surveyed boundary.
