60s F. Fishing is fair. Summer has hit the Upper Sac, which means concentrate your efforts for the morning and evening hours. Midge pupa also produces. Use 6x tippet. Evening dry fly fishing is good from 7 pm to dark with PED, small caddis, and attractor dries.
Most consistent stretch is from Box Canyon downstream to Soda Creek.
If you want to fish the lower river, do so early in the day and move upriver to Dunsmuir as day progresses and the water warms. Early and late in the day is best, but find a shaded area and you will find willing trout. Fish in the Devil's Postpile area. Indicator nymphing is best bet. Best action is from early morning to 11 am, and again from 5 pm to dark, but fishing is holding up during the day.
