Fished it a few times. Always had my best success on a full sinking line and dark flies like black buggers, though I did catch some fish on a solid white bugger.
Never fished the evening but I bet there is some dry fly opportunity. I’d definitely take a floater. Was driving by there once on a non fishing trip and the fish were going crazy on white moths, spruce moths I assume.
Good luck and have fun.
