Wing dam in a man-made river bed. A wing dam or wing dike is a manmade barrier that, unlike a conventional dam, only extends partway into a river. These structures force water into a fast-moving center channel which reduces the rate of sediment accumulation while slowing water flow near the riverbanks.
Rocks, wood, sand and other natural materials build up at the mouth of the reservoir instead of dispersing through the riverâs meandering channel. âDownstream of a dam, the river is starved of its structural materials and cannot provide habitat,â reports HRC. Fish passage is also a concern. âMost dams donât simply draw a line in the water; they eliminate habitat in their reservoirs and in the river below,â says HRC.
