In my 3+ acre E Texas pond I checked temp and DO yesterday, it was a really nice day. My water temp was 52.5 at 9'(my probe is limited with a 9'cord). The water temp was 52.5 from 9' to near the surface where the surface was 60. Pond average water depth is 7' with the deepest being 10 and 12 foot when full pool(pond has two different pool areas) The DO was 8.8 or 76.6% from top to bottom except along the windy shoreline where the DO was 98 to 99% at 3' to the land. Pond aeration(diffusers) were turned off about 5 days ago or just before this last cold front. As I understand it, at my sea level and with my water temp steady 52.5 from top to bottom, an 8.8mg/L or 76.6% is good to go. Diffusers will remain off till late Feb or March

Do not judge me by the politicians in my City, State or Federal Government.
