Bonneville Dam can be seen in the background and the raceway where a cofferdam was needed in the foreground. The 8ft tall AquaDam will be placed down inside of the raceway.

Workers prepare a rope anchoring system to hold the AquaDam in place, as it is filled with water. There is nowhere to tie the ropes for anchoring the dam inside of the channel, just vertical concrete walls.

The 6ft tall single closed end (SCE) AquaDam has been placed down into the channel, where it will be installed. AquaDams are shipped rolled-up like a carpet roll, wrapped in a protective covering, and with lifting straps/rope.

A worker has unrolled a few feet of the 6ft tall SCE AquaDam, so that he can tie the ropes to the starting point (open end), place the discharge hoses into the fill-tubes (black shiny material), and restrain the open end higher than 8ft up the wall. Notice the sandbags at the bottom right, they are there to help with any seepage that may occur at the 90-degree corner.

Here we can see the rope anchoring system developed to restrain the open end of the SCE AquaDam. The workers created the starting bank needed for a SCE AquaDam. The blue discharge hoses have been placed and secured into the fill-tubes.

The 6ft tall SCE AquaDam has unrolled enough length that it has made it to the opposite wall. Sandbags were also placed at corners here as well.

Both ends of the 6ft tall SCE AquaDam have been restrained with ropes and the unit is being filled with water. The roll end was fastened so that as the dam fills, the roll will not lean or unroll in unwanted directions.

The 6ft tall SCE AquaDam continues to fill. Workers monitor the roll end as it fills to be sure it stays where intended.

As an AquaDam is filled with water, the restraint ropes should be checked and adjusted as needed.

The 8ft tall SCE AquaDam is nearly full now. The folds seen at each end are due to the rectangular shape of the channel and have no effect on the performance of the AquaDam.

A smaller SCE AquaDam was installed just downstream of the 8ft tall unit. Notice that both ends, starting point and rolled-up end, have been restrained just like the previous larger dam. These restraints help keep the water inside of the SCE AquaDam and keep the unit in place as it is filled.
