A view from the other direction. It shows the AquaDams® coupled together. The 8' high AquaDam® is being unrolled by the water pressure produced by the pumps (sitting on the previously filled AquaDam®). 

The two workers standing on the big AquaDam® are waiting for the white AquaDam® to unroll. Notice the roll of black material at the end of the larger AquaDam®. This is the attachment collar. Later in the project it will be used to attach another AquaDam®. 

As planned, the installation of the white AquaDam® is being unrolled under its own internal water pressure and is being placed alongside the larger AquaDam®.
