Is the Hudson River Salt Water?
The Hudson River is not what you think. It’s one great big tidal estuary. That means salt water from the ocean pushes up with the tides and combines with fresh water from smaller rivers that come down from the mountains. The Catskills and the Adirondacks feed fresh water through tributaries feeding into the Hudson, flowing south, and the tides pushing in from the Atlantic Ocean mix to make what’s called Brackish water.
You can actually see high and low tides in Albany, NY and other places along the Hudson between Troy and NYC. That’s about 150 miles of river and brackish water. The ebb and flow of the tides means the Hudson River supports a wide diversity of aquatic life, as well as breeding grounds.
