One 6' x 100' AquaDam® blocked off the Cedar River, forcing water
to flow through a newly constructed vinyl-lined diversion canal.
Notice the brown, muddy water behind the AquaDam® in the work area.
This picture shows the start of the diversion channel.
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.
