It’s a cold time of year in Big Lost River country, so dress accordingly if you plan to fish there. During cloudy days some good BWO emergences remain, other than that most top water fishing is for trout taking midges. Small (#16-20) bead head nymphs of your choice also work. With flows below Mackay Dam at 200 cfs, water is ideal for wading, but sure is cold.
With flow out of Mackay Dam at just over 200 cfs, wading conditions are great and there is enough water to give fish good overhead cover. Days of good weather are limited, so get out and enjoy trout responding to the afternoon BWO activity.
With flow out of Mackay Dam dropping near 300 cfs, the river below is in great shape for walk-in wade fishing. This time of year tricos begin attracting fish in the mornings, and flavs take over in the afternoons. Of course the tricos are more numerous! The other big attraction to fish will be terrestrial patterns. The real old-timers fishing here prefer to fish streamers as darkness falls. So consider!
With flows out of Mackay Dam close to 500 cfs (that’s close to normal for this time of year) , wading with caution can be done in the river below. A few golden stones may be hanging around, but caddis life cycle patterns and dry attractors might bring the best top water action. Try rubberlegs, medium sized (#8-10) wooly bugger types, soft hackles, and your favorite bead head nymphs for below the surface.
