The Hudson River averages about 30 feet (9 meters) deep along much of its navigable length, but its deepest point plunges to around 200–203 feet (about 61–62 meters).

Quick Scoop: How deep is the Hudson River?

  • Average depth (south of Troy, NY): about 30 feet (9.1 m).
  • Typical maintained shipping channel depth (NYC–Albany area): about 30–32 feet (9–9.7 m).
  • Around New York City harbor and lower Hudson: mid‑channel depths commonly exceed 40 feet (about 13 m).
  • Deepest point, called “World’s End” (between the U.S. Military Academy at West Point and Constitution Island): about 202–203 feet (61–62 m).

So, if you imagine most of the river being roughly a three‑story building deep, the very deepest hole is more like a 20‑story building of water stacked straight down.
