Two auto-venting turbines installed at Norris Hydro Plant to increase dissolved-oxygen levels are briefly described. The turbines introduce aeration through the thrust relief openings, the deflector, the trailing edge of each blade, and the periphery of the draft tube. Downstream dissolved-oxygen levels have been increased by up to 5.5 milligrams per liter. Efficiency losses range from 0 to 4 percent, depending on operating conditions and aeration method.
