Impoundment destratification by mechanical pumping
lake volumes were 98, 100, 120, and 1260 acre-ft; each impoundment was thermally and chemically stratified before pumping began; equipment was pontoon-mounted, axial-flow pump, 13 acre-ft/day capacity, driven by gasoline engine; pump drew water from bottom and discharged it at surface; profiles of temperature, pH, and concentrations of dissolved oxygen and carbon dioxide were taken before and after pumping; data presented show that this method was effective in destratifying these lakes; water quality was improved and entire impoundment could be mixed with pump located at single position.
