Soo Locks - U.S. Army Corps of Engineers by Michelle Hill |

The nearly empty lock from the West, from here you can see the debris
pits and sills on the lock floor. |
_small.jpg)
A nearly empty lock. The rectangular openings are where water flows in
and out of the lock depending on if the lock is being lowered or raised.
|
_small.jpg)
Two workers use a special wrench to open a valve that will allow water
to flow from the debris pit on the other side of the lock gate into the
lower end of the lock where it can be pumped out. |
_small.jpg)
A view of the lower gates from the lock wall. |
_small.jpg)
The lock nearly empty, the Harvey comes to rest on the lock floor.
|
_small.jpg)
The culverts towards the right, each approximately 12 feet high and 8
feet wide carry water out of the MacArthur Lock when boats are being
lowered. With the lock nearly empty only a small amount of water was
moving through them when the photo was taken. |
._small.jpg)
Special cribbing is secured to the deck of the crane barge Harvey, she
will eventually come to rest on the lock floor on this cribbing. The
dewatered lock will serve as a dry dock so crews can inspect and work on
her hull. |
_small.jpg)
The Davis and Administration Building each have a designated electrical
switchboard that provides power to the pumps. This switchboard provides
4160 volts of AC (the standard house takes 120-240 volts) |
_small.jpg)
Standing between two 350 hp 30 inch pumps, two workers look into the
deep well. There are "deep wells" below the Administration and Davis
Buildings. Extending 100 feet below ground level, these wells are deeper
than the locks. Gravity causes the water to drain into the wells when
the valves are open and the pumps remove it, much like a sump pump in a
home - only on a much larger scale. |

The lift supervisor watches to ensure that the log remains balanced and
lines up correctly with the slots in the wall. |
_small.jpg)
A man at each end holds a rope and is able to help swing the 29 ton log
to ease it into the slot in the lock wall. |
_small.jpg)
Stop logs form a temporary dam at the upper end of the MacArthur Lock so
it can be dewatered and its gates inspected. Here one of the first of
the 29 ton logs is swung over the canal into position. |
_small.jpg)
On the lock wall an operator controls the ROV as it records video
footage from the lock floor. |
_small.jpg)
The Soo Area Office's remotely operated vehicle camera is prepared to be
lowered into the water. The ROV can get into spaces too small for divers
to enter. |
_small.jpg)
A diver uses a ladder to climb into the 37 degree water to reach the
lock floor where he will inspect the areas around the gates and valves
and assist with debris removal. |
_small.jpg)
Dive tenders assist a diver with his gear in preparation for dewatering
the MacArthur Lock Dec. 17, 2012. The Buffalo District provided this
U.S. Army Corps of Engineers dive team. |
_small.jpg)
The tug Owen M. Fredick will be lifted and placed on the barge to the
left where she will spend the winter having parts of her hull replaced.
|
_small.jpg)
Before removing the chain slings from her bow and stern crews will
secure the tug to the deck with cables and braces at the bow and stern
on both sides of the tug. |

Buffalo appears to be sailing on a cloud as it approaches the MacArthur
Lock Dec. 11. |
