This AquaDam® is abutting the side of the levee that is stable. This section goes over the mud tubes which go directly underneath it. The Arcata slough is in the background. The Pacific Ocean is beyond the canopy of trees in the background. Notice that one side is dry, while the other side is holding back the bay waters.

Two months after the installation the pasture land is green and most of the water has drained off.

You can see the high water at high tide. It is only 2' below the height of the AquaDam®. To increase its retention capacity, we put fill material directly behind. After the levee breech has been fixed, a bulldozer will level off the pasture land for re-seeding.

Before the AquaDams® were installed, the water was rushing past the barn. During high tide, all of the pasture land was covered in water. This picture shows the middle section of the three AquaDams® which made up the 450' linear feet of temporary, water-filled levee.

This is an aerial view of the entire levee breech area. You can see that the fields are returning to their normal state, the water having drained off. The dairy cows are happy and the owner can return to his work. Once again, AquaDams® and the Water Structures team saves the day!.
