This paper describes the installation and testing of an oxygen diffuser system in the forebay of TVA's Douglas Dam. The diffuser system is made up of plastic pipe frames and porous hoses that spread very small oxygen bubbles over a large area near the bottom of die reservoir. Operation of the system has demonstrated very high oxygen transfer efficiencies and a capacity to increase die hydropower discharge by 3 mg L−1 of dissolved oxygen.
