There is a little more dissolved o2 at the dam than other parts of the lake, but not much. As of 10/1, throughout most of the lake there was less than 1.5 mg/l of dissolved below 40 ft. (less than stripers can tolerate) At thirty ft. it rises to about 2.5 mg.l. Above 30 ft. there is plenty of o2. I wouldn't expect the fish to go deep any time soon. I think the worst is over as long as the upper levels don't become too hot. Hope for an early fall.
