Title: Evaluation of release improvement techniques for J. Percy Priest reservoir. Final report

Technical Report ·
OSTI ID:6654186

The J. Percy Priest Water Reservoir Project has experienced problems with the water quality of hydropower releases. During the annual stratification season (approximately May to November), the hypolimnion becomes devoid of oxygen creating a chemically reduced environment in which iron, manganese, and hydrogen sulfide become soluble. Upon hydropower generation, the oxidation of hydrogen sulfide creates a 'rotten egg' smell downstream. The methodology selected for improving the quality of the release was to install a localized mixing system in the reservoir in front of the hydropower intakes. The purpose of this report is to document results of field tests and the validity of the original design formulas (Holland 1984), and to better determine the number and location of pumps required to meet the desired release DO of 5.0 mg/1.
