Popis:	The progress made in the past two years on improving dissolved oxygen (DO) and flow conditions below Tennessee Valley Authority (TVA) hydropower projects is discussed. New methods of turbine aspiration have resulted in dissolved oxygen increases of up to 3.5 mg/L with efficiency losses of about 0.5 percent. A regulation weir made from gabions has provided a continuous minimum streamflow of 5.7 m3/sec below a hydropower project where previously no flow had existed for extended periods. Comparisons between sluicing, adding a small hydroturbine to the powerhouse, providing a regulating weir, and pulsing existing turbines resulted in the selection of a small hydro addition to provide a continuous minimum flow below a second project.
