I think the poor water quality (low oxygen levels) at depths this year that Duayne mentions is in large part the result of the sluice gates being opened. Not sure how long they were open but pretty sure it was at least a week back in mid August when I saw them and a lot. lot , lot of water was coming out. The sluice pulls water from much deeper where the colder oxygenated water is where the stripers of size usually hang in late summer. I have no idea why the sluice was open or how long it was open. Duanye is right, the depths he mentions has very little oxygen. It's a dead zone.

When the dam work was being done they opened the sluice in late summer to put colder water in the river I was told and that helped the Trout. I don't remember them being open before the dam work but I could be wrong as I was not down there much before that.
