blair - Be prepared, DO meters are not cheap expect to pay around $500+-$1000. If your needs are only a few tests per year it would be cheaper but more time consuming to use a liquid or chemical test kit for measuring DO. However, In this case you would need to use a water sampler that could capture a discrete water sample at a specific depth without exposing it to very much air. Air bubling into a container adds oxygen to the water sample. There are home made discrete water samplers. Is there a lake mgmt company near you that could come out and at a fairly reasonable cost sample the DO once a yr?
