Conditions

The Owyhee is running low and clear in early September, holding steady around 116 cfs. Cold water and excellent clarity make this an ideal setup for sight-fishing, especially in afternoon riffles where larger fish feed actively. Midges dominate the morning and early afternoon in sizes 20-22, then BWOs take over around 2 p.m. and continue through the later afternoon. Both nymphing and dry-fly presentations work well when fish are keyed on the hatch.
