Abstract
Discharges from stratified hydroelectric generating impoundments are frequently drawn from the hypolimnin due to the low elevatin of the penstocks. The hypolimnion contains the colder water and thus provides a cold water fishery below the dam. Oxygen depletion within the hypolimnion results in very low D.O. levels in the waters being discharged. Economic analysis of supplemental areation techniques found hypolimnion oxygenation with commercial oxygen had the least cost. The seasonal oxygen deficit was 7500 tons to provide 6 mg/ D.O. downstream. The maximum daily requirement was 110 tons per day. On-site production of cyrogenic oxygen was estimated to cost about $30 per ton. Pulsed oxygen injection at the dam with the oxygen injection rate matched to the peaking power discharge rate added 6 mg/ D.O. with 85% absorption efficiency. Continuous injection of 100 tons per day of oxygen at a location one mile above the dam resulted in 50% withdrawal of the injected oxygen.
