I want to know the answer to the following question:
What man-made body of water was designed in part by George Washington?
All the background I'm provided with is that "The resistance to the slave trade was growing by the mid-nineteenth century; in one famous case in 1848, Henry "Box" Brown made history by having himself nailed into a small box and shipped from Richmond to abolitionists in Philadelphia, Pennsylvania, escaping slavery.". Is that enough to answer the question?
Answer: no
