Fall fishing is hot at Lake Powell and will remain very good for the next 2-3 weeks. After that it will trail off and most fish will be less active during the cold of winter.
Wayne Gustaveson provides an excellent weekly report on Lake Powell fishing conditions. See it here.
Below are a couple quotes from his latest report:
Magic 60-degree temperatures that caused bass and striper fishing to peak in the spring will be duplicated during the next 3 weeks. Look for a fall flurry of fishing success similar to that found in spring. Use your favorite technique at your best springtime spot to have great fishing success. Crappie are being caught in trees now and will continue to provide good catches until mid November.
Striper fishing success has never slowed in the San Juan Arm where adult schools are guarding the mouths of Piute and Neskahi Canyons and deep water in between. Fishing success at Good Hope Bay and Hite is less certain with few reports coming from there this week. That may be due to the steady striper fishing success in Bullfrog and Halls using the same spooning and trolling techniques described above.
