The area where the AquaDams are to be placed is being cleared of debris (rocks, sticks, glass, etc.) that may be in its given path.

Debris clearing and starting bank construction. In this image we can see, workers are clearing the path where the AquaDam will be placed, and an excavator is constructing a bank to start the AquaDam from. Single closed end (SCE) AquaDams require a starting bank that is greater in height than the maximum height of the AquaDam along it’s given path. The starting bank should be wide enough to allow the AquaDam’s starting point to lay flat up the slope.

Before installation, verification of the proper length of AquaDam should be done. In a line configuration like shown, you will need to measure the wetted perimeter plus the starting and ending banks.

Before pumping, guide rope(s) have been set and the AquaDam is aligned into position, which must be perpendicular to bank toe.

The AquaDam’s fill-tubes are being pumped with river water, using two 3” Honda WB30XT pumps. The pumps will do the work of unrolling.

AquaDam1 is filling and is approximately 20’ across the river. While crossing flowing water, the AquaDam is maintaining head, so it has contact with water’s bottom.

AquaDam1 continues filling across the river, looking upstream. When crossing flowing waters, the AquaDam must have head above the water to help maintain its location.

AquaDam1 was not long enough, and the contractor attempted to place fill material in the gap to help the seal.

AquaDam2 will be full soon and people are able to walk on it. This photo was taken standing on AquaDam1.

AquaDam2 almost filled. This photo was taken upstream of diversion intake facing downstream.
