I was flyfishing with weighted nymphs just under the surface. Black and gray colors worked well. Saw others catching them with flyfishing gear as well as casting the "U" shaped metal lure in gold or copper.
When I cleaned the trout, 4 of the 5 had empty stomachs; 1 trout was full of orange PowerBait.
Limit of trout:

PS: The "U" shaped metal lures were Super Dupers. However, Kastmasters were also taking trout.
