Bill - a more general question regarding one of your above comments. You stated that with a water clarity of @18", the DO below 4 feet would rapidly be consumed. Is there a general rule of thumb for water clarity depth and oxygen generation. For example, from your comment above, it would seem that approximately 3 times the water clarity would yield the depth to which oxygen is being generated by the phytoplankton.

One of the reasons I am asking that question is a friend of mine has a 6 acre pond with good depth and plenty of shallow water but it remains muddy year round and visibilities rarely are even as good as 1 foot. Despite the muddy water, it is one of the best bass fishing ponds I know of. Just wondering about the DO at various depths in a situation like that. Have often caught some nice bass around a rock/wood pile which is surrounded by water of 8-15'....sometimes in deeper water and sometimes in the shallows around the rocks.

Just wondering.

When you are right, no one remembers; when you are wrong, no one forgets.
