The fish enter the fish ladders, which resemble a maze, and are led back upstream through the swimming of the fish ladders, taking the fish from the lower end of the river to the higher end. The fish ladders also allow protection for the juvenile fish traveling back to the ocean. The fish and the ladders may be viewed from below the dam through windows that were especially built for viewing and counting the fish. Each fish that passes through the ladders is counted and recorded. It was interesting to see the thousands of fish that go through this area every day. The Army Corps of Engineers did a remarkable job engineering this dam and changing the topography of the area while maintaining the
