The Hudson River in New York is a significant waterway with a depth that varies along its course. Understanding the depth of the river is crucial for navigation, environmental management, and recreational activities. In this blog post, we will explore the depth of the Hudson River in New York City and the surrounding areas.
What is the Average Depth of the Hudson River in New York City?
The average depth of the Hudson River in New York City is approximately 30 feet (9.1 meters) south of Troy. However, in the lower Hudson River, the depth is 43 feet or more in midchannel from deep water in Upper New York Bay off Ellis Island to the upper limit of New York City’s major wharves at 59th Street.
How Deep Does the Hudson River Get?
The Hudson River originates from Henderson Lake in the Adirondack Mountains at an elevation of 1,770 feet (540 meters). Along its course, the river reaches a maximum depth of 202 feet (62 meters) at “World’s End” between Constitution Island and the United States Military Academy.
How Does the Depth of the Hudson River Vary Along its Course?
The depth of the Hudson River varies significantly along its course. At its southern course close to the Federal Dam, the river reaches a depth of 9.1 meters (30 feet). However, the river narrows considerably in the Hudson Highlands between Putnam and Orange Counties, flowing between mountains such as Storm King Mountain, Breakneck Ridge, and Bear Mountain.
The river also widens significantly at Haverstraw Bay, the widest point of the river at 3.5 miles (5.6 km) wide. This variation in depth and width is due to the river’s geological history and the influence of tides and currents.
What are the Key Facts About the Hudson River’s Depth?
Here are some key facts about the depth of the Hudson River:
| Fact | Value |
|---|---|
| Average Depth in NYC | 30 feet (9.1 meters) south of Troy |
| Maximum Depth | 202 feet (62 meters) at “World’s End” |
| Depth at Federal Dam | 9.1 meters (30 feet) |
| River Watershed Area | 14,000 square miles (36,000 km²) |

The Hudson River’s depth is a crucial factor in its navigation, environmental management, and recreational activities. Understanding the variations in depth along the river’s course is essential for ensuring safe and efficient transportation, as well as for managing the river’s ecosystem and resources.
