This 3ft (1 m) tall single closed end (SCE) AquaDam launched well up and over the railing to ensure that it would be able to fill completely to its full height and none of the water inside could drain out. The starting point (open end) was tied back to lend it extra support while it was filled with water. A SCE AquaDam requires a bank to keep its open end higher in elevation than the body of the AquaDam. The railing here provided the needed height and restraining points.

You can clearly see how the fill-tubes come up and over the rail. The open end and fill-tubes of a SCE AquaDam must be elevated higher than the full height of dam along its given path. An AquaDam will only reach its full height at the lowest elevation along its given path. This photo shows low tide.

The 3ft tall SCE AquaDam continues to fill with water as high tide is reaching its peak.

A close-up view of where the AquaDam abutted into the concrete wall. Minimal seepage got through; the ground is only damp. Extra material of the AquaDam was gathered into the toe of the railing wall (prior to filling) to help make a better seal.

The 3ft tall SCE AquaDam is almost full as the water continues to rise.

During high tide, the beach protected by the 3ft tall SCE AquaDam remained dry. The water depth was approximately one and a half feet (0.5 m) deep. It looks like less, but remember that the beach continues to slope down, so the right side of the AquaDam is slightly higher than the left side, in elevation.

Spectators around Dabchicks Sailing Club enjoy the de-watered area, thanks to the AquaDam. Fantastic job AquaDam!
