Agreed. Too cold.
Also, the number of trout in there may be very very low. Unless it gets a fall stocking. I didn't check on that, but the PFBC website has the info.
That stream gets very warm in the summer. The number of stockies that survives the summer is probably low.
It's a good smallmouth stream, though. Try it for trout in the spring, smallies in the summer and fall.
