I'd try the Williamson River. It can be fished from the bank or drift boat or larger boat in the lower streches. It has world class trout throughout. The lake should be warming up which sends the fish up the river. Flies or spinners are the ticket on the upper river near Chiloquin and large spoons or rapalas are the way to go on the lower river. If the lake isn't too green it is a fantastic fishery. Ask the sporting goods counter in Big R, they're a lot of help. Good luck.
