Abstract
Conventional aeration of winterkill lakes results in lDlxmg. of the water
column and open water in the ice cover. A non-mixing winter lake aeration
system has been designed and field tested that can maintain water
temperature stratification in the lake and not create open water. The
performance of a cascade aerator was evaluated for which the design discharge
and dissolved oxygen input rate were 85 lis and 70 kg/d, respectively,
Unusually high levels of dissolved oxygen due to photosynthetic productivity
under the ice-cover were also observed and are reported.
