 An AquaDam® 2' x 100 feet long will be used to restrict the flow. This AquaDam® is unrolled more than the AquaDams® in Phase 1 because the bank here is much less steep.

As in Phase 1, the AquaDam® is laid out on the gravel bar and maneuvered into position by hand. The pumps are then set up and primed.

The pump hoses are inserted into the fill tubes and filling begins. Due to the slight grade, it is more important than ever to have workers in front of the AquaDam® to maintain pressure.
