The AquaDam® has been installed past the 80' mark. There is less
than 20' (notice the mark on the AquaDam®) to go. The stream bed
drops steeply (1.5') in elevation within the 100' span of the
installation and makes it hard to maintain sufficient head at the
other end to prevent it from moving.
The workers are turning the AquaDam® so that it meets back up
with the bank, making a wide U-shape around the two-lane bridge
pier. The workers have to stop and hold the AquaDam® in place to let
pressure back up each time they unroll it a few feet.
The last part of the AquaDam® is unrolling. All crew members must help so
that the last pair of legs behind the AquaDam® can be removed without being
trapped between the bank and the dam.
