There are four wing dams on the right and five on the left.

At the location of the mid-course bridge, two wing dams are directly across from each other, narrowing the channel by one third.

The wing dams still serve their purpose, but to a lesser extent than before.

While wing dams assist in assuring that rivers are navigable, they can also pose a threat to boaters.

On the other hand, fishermen intentionally fish the waters downstream of wing dams.

A wing dam is a type of river groyne (or groin, in US usage).

The wing dam on the left side was moved downstream into section four.

We worked around the wing dam at the top of riffle.

In 1868, the Corps began to experiment with wing dams and dredging to sluice out a 6-foot (1.8 m) deep channel.

But the wing dams also proved inadequate and steamboats were not willing to risk the passage.
