ABSTRACT:
The hypolimnion of thermally stratified water bodies is oxygenated by withdrawing water therefrom at rate of 10-200 percent of the hypolimnion volume per month, pressurizing the withdrawn water to superatmospheric pressure below 125 psig, injecting at least 80 percent oxygen gas at rate of 5-300 lbs. O.sub.2 per million pounds withdrawn water but less than a rate to result in O.sub.2 supersaturation at the remixing point, returning the mixture through conduit means and remixing same at rate to produce specified frictional head loss.
