Very nice flyfishing for trout and whitefish in the first few miles below the reservoir. Watch your step, though. The rattlers are thick down in the canyon, and range from the edge of the water all the way up to the rim. Last time I was there I got to see two "up close and personal." Kept me regular, though. :shocked:
Try some scuds in 12,14, 16. I hope you will release most of your fish below the dam to perpetuate the fishery.
And don't forget the Tastee Freez in Prineville across from the Courthouse. Their Mountain Burger will test your limits!
do what old coot says, plus fish the lake for crappies and smallmouth. Jigs, small crankbaits.
River is great below the dam, small fish, just try to relase the big ones, they are uncommon and should be protected.
