South Fork, October 13th, 2020

From Squaw Cr. Dugway (800x600)

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.

Just above Heise Br. (640x480)

Flow is just a bit higher than normal for the time of year: around 6000 cfs at Irwin, 6630 cfs at Heise, 3280 cfs at Lorenzo.  Water is crystal clear and cooling.  Only sad happening is that fall colors will soon be a thing of the past. Riffle fishing seem to be picking up with BWO and mahogany dun action bringing fish up.  Add caddis activity during PM.  With a stormy weekend predicted this action may get even better, but do not overlook presenting streamer patterns.

Even through flows are where they should be ( 5980 cfs at Irwin, 6590 cfs at Heise, 3100 cfs at Lorenzo), action has slowed a bit, especially around riffles, during these bright, clear days.  We need some stormy (with rain) weather to help increase fish activity.  Regardless, as we move through October, streamer fishing will pick up as brown trout migrate to spawning areas.

Don’t expect to see big aquatic insect hatches during these windy days. Those bugs get blown away before mating and know it.  Cool air temps will also slow down terrestrial insect activity.  So think streamers and nymphs. And be sure to have rubber legs in that fly box. That pattern seems to remain effective throughout the season on the South Fork.

The constant flow out of Palisades Dam, about 7000 cfs (  about 7600 cfs at Heise, about 3300 cfs at Lorenzo ) makes for good fishing and a lot of places for walk-in fishing. BWO, mahogany dun and caddis activity are making the dry fly fisher happy. Even a few mutant golden stones remain, but do not overlook pitching a streamer during the evening hours.

South Fork, September 12th, 2020

It’s been a good end of the summer fishing season so far. Flow out of Palisades Dam was dropped to 6600 cfs ( 7300 cfs at Heise, 3360 cfs at Lorenzo) Thursday, 9/10.  This opens up many more walk-in wade locations to enjoy fish responding to BWO, mahogany dun and caddis activity.  Shorter days with earlier evenings mean streamer patterns should be in that fly box.

South Fork, September 5th, 2020

Flow out of Palisades Dam was dropped to 8230 cfs Thursday ( 9160 cfs at Heise, 4160 cfs at Lorenzo).  Looks like we may have some more BWO weather right after Labor Day. Forecasts say cool and cloudy, so “just what the doctor ordered” if you are waiting for the Fall season.  That season won’t start officially until about 9/20, but Ma Nature likes to tease us a bit when it comes to weather.

South Fork, September 1st, 2020

Our rainy day yesterday brought BWOs out on the South Fork.  Their numbers were only temporary because we are back to summer weather. But that temporary presence means they are waiting for more permanent cool weather to begin emerging big time.  So if you fish the South Fork, it is time to stock up on BWO life cycle patterns.

SF With Baldy 2 (640x480)

No big change since our last report. Flows remain about the same throughout except for a 700 cfs drop out of Palisades Dam drop on Wednesday.  Mutant stones greet early AM fly-fishers.  Fish are responding best to hoppers and other terrestrial insects on the river below Heise.    Riffle fishing varies day by day, but PM caddis activity seems reliable almost every day. If you are considering a float trip downstream from Twin Bridges, be advised that someone in your group knows that part of river.  The river in that section can be tricky with blind side channels and dangerous snags and sweepers. It is a good example of a “living river.”

We are starting with good conditions for the upcoming fall fishing season: clear  water, suitable flows, and cooling weather.  A lot of folks are looking forward to the BWO and mahogany dun activities which the fall season features and also the increasingly later effectiveness of presenting streamer patterns to amorous brown trout.
