Four months later, work on the dewatered side of the lake is finished, and the AquaDams® had to be moved to allow the other side to be worked on.

As the AquaDams® are reinstalled, one worker breaks the ice with a crowbar while another keeps it from injuring the unit.  

As you can see, the ice is rather thick, so this is definitely not an easy task.
