Gravel Bag Berms and Check Dams — 3 Comments

  1. Please note that the water flow in the photograph is moving from right to left. The wing on the check dam points downstream, creating an eddy that sucks the sediment in behind it where it is deposited in the slower current. I have seen large check dams installed on the Colorado river just for this same purpose. BTW, the check dams make great fishing spots, too, if they are installed on a stream or river.

    • I’m pretty sure the water is flowing from left to right. Note how most of the water is behind the check dam (left) and almost none below (right). Sediment is building up and overflowing around the right side.
