Abstract
A method for enhancing or generating a water flow current by the generation of a velocity head differential, to guide fish, including: a venturi eductor to induce higher water pressures; a pump, piping or other motive water source; an adjustable frame to mount the venturi eductor; and a method of using this equipment. Fish may be guided into or away from a waterway area by generating or enhancing a current to guide them. The apparatus may be used as a method to guide fish through low velocity areas of a river, lake, reservoir or other waterway. The apparatus may also be used as a method to create water flow velocities that fish are reluctant to pass through for a barrier or curtain to further guide the fish. The apparatus and method may also be used to transfer temperature-variant water in a waterway.
