Pond Boss Forums AERATION Should I aerate? How many aerators should we have

Ric - In additon to Ted's reply which was good advice. You will find that oxygen meters are pricey ($400-$800).

The first thing I would do in your situation, is go to a local marina and or a Walmart or place that sells electronic outdoor/indoor weather thermometers battery operated with at least a 10 ft temp probe. Marina's often have a simple cheap battery operated boat thermomoter with a 20 ft probe for $20 (AirGuide) . Attach a weight to probe end and once a month in June, July, August, and Sept perform a temperature profile of your lake in the deepest basin. Take temperature readings at every foot of depth from surface to bottom. Come back here and post your results and we can tell you how well the wind is mixing your lake and the likelyhood if oxygen is at the bottom. It would also be good if you made a note of the water clarity of the depth you can see a white coffee cup when you make the temp readings.
