Abstract
Currently migratory fisheries are impeded in their upstream and downstream movements by one or more dams across rivers. A method and structure is described that overcomes the shortcomings of currently employed methods such as fish ladders, water spilling and barging. A channel of sufficient dimensions to simulate a natural stream bed is employed to parallel the entire length of river and reservoirs and provide passage for the fish. This is accomplished without the breaching and destruction of the dams bypassed.
Claims1
A process and structure to allow migratory fish to bypass dams and reservoirs in a river, with a manmade channel parallel to the river, that would follow the original grade of the land as to when it was a free flowing river and would be so constructed so as to allow free passage both upstream and downstream for migratory fish along the entire stretch of dams and reservoirs to create additional spawning habitat along its length and overcomes the shortcomings of currently used fish ladders, barges, and water spillage without the breaching and destruction of the existing dams with their multiple benefits.
