The river helps the BWO and mahogany dun activity by having a near constant flow ( 6050 cfs at Irwin, 6700 cfs at Heise, 3550 cfs at Lorenzo) of clear, cool water for several days, but it looks like a drop in flow out of Palisades is coming up. Everything these unsettled days works in favor of mayfly activity except for the WIND, that is, and lately it has been fierce during afternoons when they should be most active. So expect slower action when wind comes up. But that is not the case with streamers. Bad weather usually means they are effective because of increased overhead cover. So continue taking BWO and mahogany dun life cycle and streamer patterns and the gear to present them during the fall season.
