Abstract:
1. A system for selectively permitting aquatic organisms in a water flow to safely bypass an obstruction by controlled dissipation of pressure in the water flow, comprising: a primary container including a container wall constructed and configured to define a container space1 through which the water flow may pass, said container wall includes a first container opening configured as a first inlet and a second container opening configured as a first outlet; said primary container including a flow control element configured to gradually lessen rate of the water flow in said primary container; a container pressurizer functionally separate from and configured to permit pressurization of said container space; and a pressure control mechanism configured to permit control over pressure level in said container space and intended to prevent harm to the aquatic organisms in the water flow during transition through the container; said pressure control mechanism separated from the water flow containing the aquatic organisms by a separator, said separator configured to selectively prevent the aquatic organisms from coming into contact with at least said container pressurizer, said pressure control mechanism, and said first outlet during passage in the water flow through the system.
