Installation of the first 8' backup AquaDam® has been completed.
Another 8' AquaDam® has been partially unrolled (you can see it
next to the black 6' AquaDam® in front of the workers) prior to
moving it to the end of the other white 8' AquaDam® for attachment.
All AquaDams® have been installed and dewatering is
almost complete. The largest AquaDam® is
approximately 13' in height. Water depth has been reduced from
a maximum of 10.5' to a depth of 8.5'. This reduced the head
pressure on the side of the water-filled cofferdam to the
agreed upon depth.
Dewatering was accomplished with four 6" discharge pumps,
set on a custom-made, floating pontoon platform, allowing it
to be moved. The bottom of the lake has become very muddy over time.
The screens had to be cleaned constantly which did not allow
for efficient discharge pumping.
