1.) During the 2007 renovation of Miller Boat Launch in Tomales Bay, which is Northern Marshall California, a 6ft tall by 74ft long single closed end (SCE) AquaDam was used to help support a sheet pile cofferdam that was already installed.

2.) Some of the piles had not been driven deep enough and support was needed on the inner perimeter.

3.) Tomales Bay is tidal, so it has high and low tide water depths that effect the area.

4.) Looks like Nick’s Cove Fishing Pier in the background.

5.) The 74ft long SCE AquaDam will be installed starting on the right and ending near the middle of this photo.

6.) The 6ft tall SCE AquaDam has been laid out and unrolled a few feet so that the open end and fill-tubes can be exposed. Two 3-inch blue discharge hoses have been inserted into each fill-tube. AquaDams are made of light weight flexible materials and will float when empty in deep enough water.

7.) A SCE AquaDam requires a bank to keep its starting point (open end) higher in elevation than the body of the AquaDam. 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. The sheet pile is acting as the starting bank for the 6ft tall AquaDam. The extend boom is helping keep the fill-tubes and hoses elevated across the gap.

8.) As the 6ft tall SCE AquaDam is being filled with water, workers held the unit up against the sheet piles until the unit had enough head above the surrounding water. Great job AquaDam!
