North Carolina Power, a subsidiary of Dominion Resources, the US Geological Survey and a group of North Carolina and federal agencies are using a fishwheel to conduct a major study on American shad and other fish species in the Roanoke river in North Carolina.

A fish wheel is a device western North American Indians use to harvest salmon. The project is part of North Carolina Power’s effort to renew its federal licence to operate hydroelectric dams at Roanoke Rapids and Gaston power stations.

The wheel has been positioned on the Roanoke river near Halifax.
