The water depth from one side of the AquaDam® to another changed by several inches. The water was disappearing on one side because it was leaking out of the low dam. This difference in water depth needed to be addressed by using the internal head water forces of the AquaDam®.

The AquaDam® stopped unrolling once it abutted into the bank which had been cleared of brush, rocks, and roots.

This picture demonstrates how the lake water drained out between the existing dam and the AquaDam®. The water did not go over the existing dam- it went through it. There is a common misconception that man-made dams are water tight. They are not.
