Recent reports indicate that you can get a lot of fish on midge pupae like #18 - 20 Zebra Midges in black and red, and the BP Weiss nymps as well. Bring your Woolley Buggers too as you can get fish stripping them with your I-line setup, black, olive and brown all can work depending on the conditons. This lake has a lot of Callibaetis and fishing a small, #18 Pheasant Tail nymph on an I-Line or under an indicator an work very well. Look for cruising fish and if they are eating up to, use a #18 or #20 Adams.

The lake is a good option if you are in the area, with intermittent releases from Trinity Lake, fishing right below the outflow can produce some consistent hookups. With the amount of Damsels and Dragonflies in this system, Wooly Buggers stripped in brown, black and olive, and Balanced Leeches the same color stripped or fished under an indicator are solid approaches. And Zebra Midges in #16 - 18, black and red, are a staple here. We've got guides who can get you out on Lewiston, give Bryan a call to set up a trip!
