This project was at Caples Lake in Kirkwood California in 2008.

Here is the overflow spillway for Caples Lake. The water level has been lowered for dam repairs.

Here is an image of Caples Lake's main dam. There is a 3ft tall AquaDam inside of the orange rectangle at the toe of the dam. This AquaDam was put into place to keep unwanted water and fish out of the tunnel underneath the dam during construction.

Two 8ft tall AquaDams can barely be seen holding back Caples Lake's water.

Here is a zoomed in shot of the two 8ft tall main AquaDam used for this project.

A close up of the 3ft tall AquaDam in action.

An 8ft tall 17ft wide (fully filled) 160ft long double closed end AquaDam with no connection collar on the left and an 8ft tall 17ft wide 173ft long single closed end AquaDam with no connection collar on the right. The AquaDam on the right has no baffle.

Two 8ft tall AquaDams were used in this application because the water depth was greater than 6ft.

When using an AquaDam to support another AquaDam, it is important to keep them close and to relief any water that may get trapped in between the two.

Due to the excess length of the 173ft long AquaDam, the unit was gut roped and tied back to itself. This allowed the AquaDam to continue filling with out continuing to unroll.

A pipe was place under the 173ft long AquaDam to help relief water between the two AquaDams.
