Cicil-- I'm a little over an hour East of you and 12 miles North of Ohio. I will check the DO again later this month in the deeper parts of the pond. We checked at the 8 foot level as that was just off the bottom at the end of the dock.
Bill-- We used a probe/meter with a 25' probe. No temp readout.
The main part of the pond (957') runs East-West
and the prevailing winds are out of the West. However, there are woods on the South, West and North sides so it is pretty protected from "normal" winds. I've seen the ads for the windmills but have not seen one in operation.
