Thanks Cecil. The pond is approx 1/2 mile from the nearest power source. Too far to run a outlet or a air hose. I've checked into windmill punps but the low cfm bothers me. I plan on checking the DO again soon in the deepest part and other locations in the pond now that I've made contact with the person who monitors the water quality in the creeks and streams around the local mega dairy farms. I was surprised at the 7.35 DO reading and expected a lower reading partly because the pond has no inlet or outlet.
