One 6' x 100' AquaDam® blocked off the Cedar River, forcing water to flow through a newly constructed vinyl-lined diversion canal.

A head pressure of water inside the AquaDam® must be maintained higher than the surrounding water to keep it stable during installation (head pressure keeps the AquaDam® from rolling). The second AquaDam® had three laborers standing behind it to keep the AquaDam® from unrolling prematurely.

The lower end of the diversion channel. Notice the clean water. The brown water is from the work area, before the lower AquaDam® was installed. Downstream the work area was blocked off using a combination of one 4' x 100' AquaDam® attached to a 4' x 50' AquaDam® with an attachment collar.
