A stream in Briceland California needed a cofferdam for construction work to be done. Here is a photo looking upstream of where a 6ft tall 13ft wide (full) 35ft long single closed end (SCE) AquaDam will soon be installed as the needed cofferdam.

Here we can see downstream towards where the de-watering was needed to do the construction work.

An excavator is clearing the starting bank, where the AquaDam will start from. The starting bank for a SCE AquaDam needs to be higher in elevation than the dam’s full height (6ft) at its lowest elevation (bottom of stream) along its given path.

AquaDams are shipped rolled-up like a carpet roll, wrapped in a protective layer, and with lifting ropes/straps. An AquaDam will float in water when empty.

The 6ft tall SCE AquaDam has been placed at the starting bank, the protective wrap removed, and a few feet of length unrolled. Next workers will pull the fill-tubes up the bank, tie the starting point (open end) back, and insert discharge hoses into the fill-tubes.

The SCE AquaDam has been launched into the stream and is being filled with water. Workers hold the roll end to allow the unit stay in place and fill. The current will push on an empty AquaDam, but after the unit enough head above the surrounding water it can hold itself. Ropes are often tied off to large trees, heavy equipment, large rocks, or similar anchors to help an AquaDam maintain its position as it fills.

Looking upstream, the AquaDam has almost reached the ending bank. When crossing flowing water with an AquaDam it is important to allow the unit to gain sufficient head to overcome the depth increase (upstream) from damming off the water course.

Here we can see the blue discharge hoses going into the fill-tubes. Looks like only one discharge hose is active, in this photo, probably filling the more on that side (upstream).

The upstream pool is increasing in depth now that the stream is dammed off. Workers adjust sandbags at their diversion point, which was a pipe diversion.

The 6ft tall SCE AquaDam continues to fill.

Part of the starting bank for this job was thinner than the width of the AquaDam, so it was cinched up with ropes.

Standing downstream looking at the full 6ft tall SCE AquaDam. The crease in the middle was caused by a rope that was not cut. This AquaDam reached 6ft in height at the streams bed (lowest elevation) and everywhere else its height was less.

Great job AquaDam!
