Description:

In 1987, the National Marine Fisheries Service (NMFS) entered into a cooperative agreement with the U.S. Army Corps of Engineers (COE) to study benthic invertebrates, sediment characteristics, and demersal fishes near pile dikes and rock groins at Cottonwood Island (Dobelbower Bar) in the Columbia River. Pile dikes in the Columbia River are used to help maintain the navigational channel and reduce maintenance dredging costs.
