• The Hudson River flows 315 miles from Lake Tear
  of the Clouds in the Adirondacks to the Battery
  in New York City.
• Many smaller tributaries join the Hudson on the
  way. A tributary is a small stream or river that
  flows into a larger body of water.
• A watershed is an area of land that is drained by
  a body of water. In the image to the right the
  area that is green is the Hudson River Watershed
  meaning that any water that falls in that area
  ends up in the Hudson River.

• concentration of salt water increases down river
  and toward the bottom of the river. This is
  because salt water is more dense than fresh water.

The New York Harbor is an Estuary

• An estuary is the ecosystem created where a river
  flows into an ocean.
• Estuaries have brackish water. That means it is
  a mix of fresh water (from the river) and salt
  water (from the ocean).
• Estuaries are extremely productive ecosystems
  because they have a lot of nutrients. They have
  the nutrients from the river and the ocean coming
  together.
