I lived on a house boat for about 15 years. The marina was 1 mile up stream from this lock and dam. The lock chamber is 600 feet long and 110 feet wide. The lift of the lock is about 60 feet. There is hardly any wind in the chamber do to the high walls. When we went through in the house boat, we would tie up to floating bollards set in the chamber wall. Going down was not to bad but when going up the currents from the fill valves could push you around. Had to stand by the floating bollard with an axe in case the bollard became stuck.
Since this lock is on a river there is not much current upstream but there could be a lot of current downstream.
On a cat the best way through one of these locks would be tied outboard of a power boat.
