The fish can be fairly challenging at times, but with persistence and a decent presentation, anglers can get into a few fish. Fish size does vary, with 7 to 20 inch fish possible. Don't expect high numbers of hookups, but there are days an angler can entice 10 or 12 fish to the fly. Last year, from a reliable source, Frank Smethurst hooked and landed an amazing bow in the 23 inch range on a large rubbery hopper-thing dry fly. The flow is low and is very clear.
Cloudy days are a bit more productive.
Blue wings and midges. Ants, beetle's, hoppers and other terrestrials. Buggers in black and olive, brown lower down in the quality waters. Caddis pupa in all sizes. Adult caddis are best represented by elk hair caddis and trudes.
