The baby whale, known as Minke, has died after losing its mother and its way.
The whale showed up on a sandbar in the creek near The Route 589 bridge.
The staff from the National Aquarium in Baltimore made the eventual decision to euthanize the animal.
The 11 foot long female was severely emaciated and was believed to be as young as two weeks old.
The body of the whale has been transferred to the Smithsonian Institute in Washington DC for research and will undergo CT scans.
