A 1' tall AquaDam was placed below the primary AquaDam. It was filled after the primary AquaDam was fully inflated. Its purpose is to better conform to the rocky channel bottom, reducing potential seepage into the work area.

The primary AquaDam continues to unroll. The 1' AquaDam is visible, coming back over the roll.

The sides of the primary AquaDam were folded in before being rolled up, to fit on the trailer. Now as the AquaDam fills and unrolls, the sides of the AquaDam will unfold to its full width of 44'
