The Hidden Valley of the Jackson and Passage Creek both hold some large trout in the deepest water. Fishing streamers such as the Shenandoah Skunk Simple Streamer size 10, Murray's Black Marauder size 10 or Murray's Pearl Marauder size 10 on a Scientific Anglers Sonar Sink Tip III Sinking Tip Fly Line will catch many of these large trout. I cast across stream and after my streamer sinks deeply I swim it back across the streambottom by stripping it six inches every ten seconds.
