It was not possible to put any more water into this AquaDam® because it was not started higher up the bank. If it would have been started another 3' higher, another foot or two of height might have been possible. The concrete blocks are 5½' high. Not starting the AquaDam® high enough up the bank is a common mistake during installation.

Only this much footage at the other end of the AquaDam® was left to spare (approximately 10'). The wooden core that the AquaDam® came rolled up on has broken. These 6" white plastic discharge pipes going under the AquaDam® are held in place by the water inside the AquaDam®. They are pumping water from the upstream side of the work area to pass the stream flow.

Two tubes of inner plastic from a 1' high AquaDam® are attached to the pipes and used to flume the water. The flume tubing has holes in the sides to dissipate the water over a wider area so that a scour hole will not develop.
