With the newly renovated 3 ac mostly <6ft deep pond in MO and after a few years maybe one year depending on productivity and water clarity do not expect the water below the thermocline or below diffuser depth after early summer to contain dissolved oxygen. Dead sinking organic 'rainout' particulates (stuff) will consume all the oxygen below any thermocline depth. If I had a pond in MO I would not aerate it during winter unless the pond was in a wooded area and it received lots of leaves or had lots of submerged vegetation during fall. Leaves and dead plants consume lots of oxygen as they decay.
