Once water begins to flow into the AquaDam®, head pressure begins to build inside it. To contain the head pressure and therefore make sure that the AquaDam® makes a tight seal with the ground, a rope is run under and the back over the end of the AquaDam®. As the head pressure becomes greater, the rope is allowed to slowly slip out and extend the AquaDam® a few more feet. Then the rope is held again until more head pressure is formed and the AquaDam® can be slipped another couple of feet.
This picture is for comparison with the one at the bottom of this page. Please note the amount of water relative to the height of the AquaDam®.
As the AquaDam® is rolled out, any rocks that have not already been picked out of it's path are removed now.
As you can see, the depth of the water behind the AquaDam® has increased greatly already.
