Ecology blocks were used to back up the AquaDam® and lend it extra support during high tide.
Each ecology block was supposed to be wrapped in geotextile fabric to prevent damage to the
AquaDam®. This did not get accomplished on all of them. The far end of the AquaDam® is left
rolled up high on the bank.
This is tidal water in summer months, so storms were not a major consideration.
However, super-high tides coinciding with full moons happened twice during the
duration of the project. At this time, the AquaDam® had to be strong enough to
control these super-high tides, which were sometimes as much as 9' deep.
Most of the high tides (two per day) were only 6½' deep next to the AquaDam®.
At low tide, there is only 12" of water next to the AquaDam®. The white pipe
going over the AquaDam® is connected to a 2" electric pump to keep the work
area dewatered.
