It all depends on the water quality of where the intake on the upstream side of the dam is. If you don't have DO problems in the cool water on the upstream side near the intake, you wont have them when you sluice the water. You would know better, but I have not heard much about DO problems in Dale Hollow in relation to the trout and other cool/cold water species. In this case, you could sluice to improve DO and temp.
I was commenting on the video which talked about DO problems on the upstream side of the dam. If you have those problems, your downstream discharge will have DO problems. There are all kinds of ways used around the country to add DO back into low DO sluice water including spraying in the air or direct oxygen injection ($$$).
These DO issues can also be in the water that passes through generator and there are more ways to deal with these also. Bottom line - bad water at the intake = bad water in the discharge.
Hope that helps,
