For this job a 4ft tall deadhead AquaDam and an 8ft tall by 300ft long main Aquadam were used.
The first installation will be a 4ft tall by 50ft long SCE AquaDam placed at the upstream side of the project area, to help break the current. An 8ft tall by 300ft long AquaDam will be installed next, in a "U" shape, around the work area.
Here is another view of the work area, prior to the AquaDams being installed.
The 4ft tall deadhead AquaDam has been installed. It was deployed to make the installation of the 8ft tall main AquaDam easier.
Here we can see where the 8ft tall AquaDam has started from, and the fill-tubes are over the starting bank.
The work area has successfully been separated from the main river and can now be dewatered to start work.
Turns may be made with an AquaDam to configure most desired shapes for construction.
Looking downstream the ending bank of the 8ft tall AquaDam can be seen.
An AquaDam may settle/sink into the mud a little bit, but this creates a terrific seal.
Here we can see the 8ft tall by 300ft long AquaDam has been installed in a “U” shape.
Having enough and/or the right pump(s) can make the job move along much smoother.
The fill-tubes must be pulled high up the bank prior to filling. This ensures that the water pumped into the AquaDam stays in the AquaDam.
The fill-tubes for the 4ft tall AquaDam have been tied up and secured so that the water inside will not escape.
If you look closely, you can see the riffles on the water outside of the 8ft tall AquaDam indicating that water is moving.
The roll end of the 8ft tall AquaDam can be seen at the ending bank.
The starting point of the AquaDam is tied off to something heavy on the shore, usually a large piece of equipment or a large tree. This helps ensure that the fill-tubes and opened end of the AquaDam does not move.

A small leak has formed in the AquaDam. The watertight extruded polyethylene used inside the AquaDam will sometimes have extremely small (dust sized) holes. This leak is nothing to worry about.

Once fully filled with water, an AquaDam has no trouble supporting normal foot traffic.

An AquaDam will only reach its maximum height at the lowest point along it’s given path. The rest of the AquaDam will taper as it goes up the shore.

All AquaDams are manufactured with a baffle skirt connecting the top and bottom of the AquaDam. This baffle skirt will minimize leaning caused by pressure differences between the river side and the work area side.

The unused length of AquaDam remains rolled up on the beam that the AquaDam was shipped with.
Ropes have been used to secure the end of the AquaDam to something heavy at the ending bank.
