This is an overview of an emergency installation to isolate a levee breech in reclamation district #762. This was located on the Arcata Slough in Humboldt County, CA. The slough is tidal water from the Pacific Ocean, which you can see at the very top of the picture.

The levee break was 150' long and required 450' of 8' high AquaDams®, installed in three sections.

Due to the poor stability of the remaining levee and the location of the break (on the bend), a larger section was bypassed to accommodate a better installation of the AquaDams®.

At low tide the water rushes out of the fields, creating very swift water which has to be controlled. The major obstacle in this installation was crossing this 5' to 7' deep channel, below the surrounding fields. The hole in the levee was approximately 12' deep.
