Diversion dam (double drop)

Diversion dam with river-wide, double-drop diversion dam. The upper drop is U-shaped, and the lower drop is straight across. The lower drop is similar to a low-head dam; parts of it flush out, and parts recirculate. There is a horizon line. It can be scouted and portaged on river right. Shortly after the diversion there is another, smaller double-drop structure.
