Lake Sediment Removal in Part 1, Page 3: |
| AquaDams have been started from two opposite banks and will meet in the middle of the lake to make a continuous wall of water-filled cofferdam to divide the lake in half. Notice the light house tower in the upper right-hand corner of the picture. | |
| 5' high AquaDams were used to back up the 6' and 8' high AquaDams. Notice the closed end on the white AquaDam. It was made with ends closed so that so that other AquaDams could be attached from both ends. This is sometimes referred to as a "plug". This makes it unnecessary to start the AquaDam up a bank. Notice the connections and fill tubes. | |
| The fill tubes come out the top, next to the end of the white AquaDam. Fill tubes allow you to slip a hose into the AquaDam and pump in water. These worked excellent for backing up the main, continuous water-filled cofferdam. Any water that seeped under the larger AquaDams would be trapped by the backups and forced to run back out in between the two AquaDams, and the pumps would be used to pump it off. | |
