(John A. Weeks III; Satellite)

Dam consists of 893 feet long concrete structure with five roller gates and 10 tainter gates. Earth embankment 2,600 feet long. Concrete overflow spillway 1,000 feet long.

"Tainter gates in Dam 6 were the first in the St. Paul District to employ independent operating machinery instead of hoist car systems." [USACE-library]

Dennis DeBruler: I Googled the towboat. It is a twin-screw with Kort nozzles, not Z-drives. So how does it get a strong sideways propwash?

Comparing the water levels at the extra lock gate, it appears the river is running high. But the gates are still in the water. Or does this dam have a small lift? I could not find the normal lift height for these locks.

The gates out of the water is another reminder that 2019 was a wet year in much of the USA.
