Small Streams, August 29th, 2020

 

Bitch Creek

Again, not much change since our last report. Streamside terrestrial insect population is at its peak nearly everywhere. Here’s a tip if you enjoy presenting hopper patterns. If a grain cutting operation is ongoing and nearby to a stream, hoppers will be on the move away from it. This means more of them end up on the water. Fish being in the water “24/7,” are aware of this and take notice. Enough said; bring hopper patterns if such activity is ongoing. Better yet, bring these patterns anywhere you try the water.

Here are a few streams to consider avoiding because of low water and hot weather (less cover and higher water temps): Blackfoot River above the reservoir, Salt river tribs coming out of Idaho, lower sections of sinks streams ( Beaver, Medicine Lodge, Camas, Little Lost). Some of the best to try these days: Teton River in the basin and below the canyon ( rattlesnakes still active in the canyon), Warm River, all Palisades Reservoir tribs, Birch Creek (in family area above Lone Pine), Bitch Creek, and Palisades Creek.

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.

Fishing is slowing down on some streams because of the extended hot, dry weather. That’s the case on upper Blackfoot River where low flow has warmed water to the point of making it somewhat lethal to play a fish for a long time.  Below the reservoir conditions are very different with around 600 cfs coming down the river to satisfy irrigation demands and making wet fly fishing the best way to go. Our weather should begin cooling next month, and irrigation demands will diminish, so better days are ahead.

Henry’s Fork, August 24th, 2020

Pretty much the same as last week. For the lower river fish early and late in the day and concentrate on terrestrial insect and caddis life cycle patterns.  A lot of folks are fishing on the upper river where early AM tricos and daytime terrestrial insects (including ants), a few speckled duns, tiny PMDs, and later caddis and spinner falls bring action in the Last Chance-Harriman section.  Two fly nymph rigs work well in Box Canyon.

South Fork, August 24th, 2020

Flow out of Palisades Dam has been constant at about 9800 cfs (10555 cfs at Heise, 5000 cfs at Lorenzo) for at least a week. Not much change since our report a few days ago.  Mutant golden stones early, hoppers and riffle-feeding mayflies and PM caddis are interesting fish.

Yellowstone Park, August22nd, 2020

 

Areal Beula Hering

Beulah (Foreground) and Hering Lakes

Any water adjacent to a road is crowded and tourist traffic through most entrances makes getting there lengthy. This really applies to the major streams in the northeast corner of the park ( Lamar River, Slough, Soda Butte Creeks). By contrast Fall River Basin streams  (Bechler and Fall Rivers, Boundary and Mountain Ash Creeks) in the southwest corner have few (Bechler and Boundary Creek) to nearly no (Fall River and Mountain Ash Creek) visits. All Fall River Basin streams and Beula and Hering Lakes are off the beaten path and require a bit of driving over gravel roads then walking to approach. Like anywhere in the Park, fishing is a bit tough on the basin streams ( AM tricos, PM hoppers, beetles and ants work best) as waters drop to base flows and are warmed by afternoons. At 7000 feet in elevation Beula Lake, however, still offers as good of fishing as anywhere in the park, and like its Fall River Basin partners requires a walk (2.5 miles) to reach.

South Fork 4

There are certainly a lot of float fishing ongoing. Just look at how crowded the Conant, Palisades, and Spring Creek boat launches are. But walk-in wade  is quite popular as seen by the number of folks on the river road above Heise.  Mutant golden stone flies are active in the early mornings and attract fish. Riffle fishing is “off and on,” so be patient. Hoppers are everywhere along the river, and caddis activity can make for good evening fishing.

Henry’s Fork, August 22nd, 2020

Hoppers are out big time on the lower river, but the fish are after them mainly in the early hours then again during evening. They are also out big time on the Last Chance-Harriman  and Flat Ranch sections river where tricos are on during morning hours with caddis during evening. As they  fade about late AM, switch to hopper and other terrestrial insect patterns (use long drag-free floats). Fishing on the Flat Ranch section is slowing down as flow out of Henry’s Lake is dropping and warming.   It’s still a good idea to have rusty spinners (#16-18) in that fly box anywhere you try the upper river.

Small Streams, August 22nd, 2020

Our extended hot dry, weather is  making fishing tough on many of our smaller streams. Some, like the Salt river tribs coming out of Idaho, are at base level flows already and warming to high water temps during daytime. Larger and spring-fed streams are still in good shape. Count Bear, Big Elk, Bitch, and Palisades Creek among these. Teton and Warm Rivers are in good shape.  Flow out of Blackfoot Reservoir into the river is up enough (600cfs ) to make for tough fishing unless you stick to the bottom. You will need a Wyoming fishing license for Greys River, but it is offering some really good fishing now with caddis and some PMDs remaining, and terrestrial insects making for action.  For up to date conditions on the Greys River, Greys River Sports , 106 Greys River Road provides the best info. On the east edge of Alpine, They offer fly fishing gear along with a variety of outdoor gear. Call them at 307-654-3474 or look their web site: www.greysriversports.com.
