SWPA, SouthWest Power Administration has been usually generating 2 units of water starting around 3pm to 4pm and running for a few hours, nothing really consistent. The weekend generation schedule has been about the same.
With the reduced flows the fish seem to be in the shoals and deeper holes or anywhere were there's moving water. Also try fishing around the moss beds.
The best bite has been early mornings before the water falls out and the day time temperatures start to get hot. Small pheasant tails, egg patterns and Midges have been working well. Small streamer patterns have been working while fishing the falling water from the boat using sink lines or intermediate sink tips.
