Modelling the effect of vertical flow-developer on ice cover / by M. Helsten, P. Hamblin, R. Baddour.: En13-5/95-09E-PDF

"Severe oxygen depletion causing massive fish kills in lakes and reservoirs occurs when ice cover prevents the replenishment of stored dissolved oxygen which has been depleted by biological demand and reduced oxygen production in the winter. Water quality of ice-covered, eutrophic lakes, can be improved by creating ice openings through which water could be aerated. A flow-developer creates an ice opening, or polynya, by circulating warmer water from the bottom of the lake. This study examines the performance of a submerged flow-developer which pumps water from a lake bottom vertically onto the ice cover"--Abstract, page 1.
