The installation of the first AquaDam® started high up the bank as shown in the last picture. The AquaDam® unrolled due to the pressure of the water being pumped inside. The crew keeps the AquaDam® from unrolling prematurely or letting the river current move it out of place.   

A second section of AquaDam® has been attached to the first using a coupling collar. Notice the 12-18" difference in ground elevation between one side of the AquaDam® and the other. You can tell the water depth differences by looking at the workers standing in the water.    

This picture is from the opposite side of the river. Both sides were installed on the same day. Notice again the extreme difference between one side of the AquaDam® and the other. You can tell the water depth differences by looking at the workers standing in the water.
