Also known as 'dredging'.

Digging | establishing a canal is not the same as dedging .. one is creating a waterway where previsely there wasn't one, the other is removing sediments from an existing waterway | lake | harbour.

No, this is significant because it’s a man made canal, as opposed to the natural waterways used for trade that we already knew about. It is far longer than the other Native American canal we know of and likely had damns to control the flow of water through it.

It was not dredging. It was a sophisticated structure to connect two distinct bodies of water. Per the article > "in its heyday it would have stretched a little less than a mile across most of Fort Morgan Peninsula, from Oyster Bay in the north to Little Lagoon in the south. Both bodies of water are at sea level, but the land between reaches up to six feet in elevation. That means anyone digging a trench across the peninsula would risk draining the water table into those sea-level outlets. The solution in this case may have been two dams at either end of the passageway that canoe travelers would have had to carry their boats around. With a shallow draft, dugout canoes would have only needed a few inches of water to pass through the three-foot-deep canal."

what point were you trying to make with your half-sentence response? To demonstrate to everyone you don't understand what 'dredging' means? Allow me to google it for you: Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors. what does dredging have to do with the article?

  I would guess that the canal they built would need dredging to stay operational. But I think the discovery is about the canal itself not about what they’d have to do to operate the canal. Not sure I understand GP’s statement but trying to find some connection.
