AquaDams will be used to divert the flow of this river to one side, isolating the other side and allowing construction of a new fish ladder.

The original 3ftx100ft starting AquaDam is visible next to the 8ftx120ft long AquaDam, behind the excavator. Fill material was placed behind the 3ft high AquaDam for added support. The 8ftx50ft long AquaDam in the foreground was used as a dead man to minimize current during the installation of the next 8ft high AquaDam, still rolled up, to the left.

8ftx120ft was installed midstream, starting from the Eco blocks, behind the 3ft high AquaDam. Another 8ft high AquaDam abuts into the bank on the downstream side of the work area.

Clockwise, starting from the top: 8ftx50ft long AquaDam, 8ftx120ft long AquaDam (above concrete structure), 8ftx120ft long AquaDam (below concrete structure), and a 3ftx100ft long AquaDam.

Work area looks great, water levels are already dropping.

The AquaDam cofferdam system has diverted the flow of this river to this side.

A very brave excavator operator is helping move a pump that will be used to dewater the work area.

Here you can see the last 8ft high AquaDam that connects the midstream AquaDams to the shore
