The 200ft long 8ft tall SCE AquaDam has been launched from the starting bank. The starting bank for this project needed additional height, so fill dirt was laid before installing the AquaDam.

Notice how the starting point (open end of black material) has been secured up and over the starting bank. The fill-tubes for this AquaDam were clear and can be seen on the left side of starting point (open end) of the AquaDam.

The 8ft tall AquaDam is filling. The empty part of an AquaDam floats, while the part being filled with water will expand until the dam has reached its maximum height.

as the AquaDam continues to fill the pressure from the water filling it pushes against the empty rolled-up part, causing the unit to slightly unroll. Ropes work great to limit the roll from unrolling, allowing the unrolled part to build head, and to make turns.

Workers begin preparing the ending bank where the 8ft tall AquaDam will end at. Both starting and ending banks should be greater in height than the maximum height of the AquaDam along its given path.

The rope tied to the outer end of the AquaDam roll and anchored back to shore, was used to help making turns.

On most occasions several ropes will be used to help get an AquaDam into the desired configuration.

A worker is retying a rope, so that the AquaDam can be pulled from a different angle.

The 8ft tall AquaDam has almost been completely unrolled as it has less that 50ft to go.

The 8ft tall AquaDam has reached the ending bank and is building head above the surrounding water.

The 8ft tall AquaDam is nearly full, and the work area has been isolated from the rest of the lake.

Workers prepare a starting bank for the support AquaDam which was a 5ft tall 11ft wide (filled) by 100ft long unit.

The support dam has been mostly unrolled and is being positioned.

The support AquaDam was pulled close to the main AquaDam so that they will be touching once filled.

The support AquaDam is filling. A support AquaDam should be shorter than the main AquaDam so that any water trapped between the two can escape.

This AquaDam cofferdam system has been installed in a horseshoe or “U” shape configuration.

The work area has now almost completely been dewatered.

Notice the main and support AquaDams are touching, just like planned.

Here was the gap (between the ending bank and the closed end of the support AquaDam) used to allow any water trapped between the two dams to be released.

Now that the work area has been dewatered, excavation and foundation work may begin

The workers are moving along with the restoration of the foundation of the amphitheater.

AquaDams provide a haven for all types of organisms.

Time to remove the cofferdam system. After pumping an AquaDam down it will start to float. Lifting, pulling, and rerolling the closed end of the AquaDam (from the ending bank) forces the remaining water inside the unit out of the fill-tubes.

A telehandler forklift works great for installing and removing a larger AquaDam.

Workers have ratchets with brackets that connect to the timber the AquaDam is being rerolled on.

Ropes wrapped around the timber can also be used to assist with rerolling an AquaDam.

The ropes around the timbers have been tied to straps that were then connected to the forks of the telehandler.

As the closed end gets lifted, pulled, and rerolled; the fill-tubes release the water inside the AquaDam into the surrounding water.

Great job AquaDam!
