Big Lost River, July 11th, 2020

 

Big Lost

Flow below Mackay Dam has been around 350 cfs for weeks. That makes for stability. Now is the time of year when golden stones and western green drakes activities take place in the river.  Most folks coming from over from Sun Valley will be fishing the river above the reservoir.

Yellowstone Park, July 11th, 2020

Bechler Meadows

The upper Gallatin River is coming on with caddis , some PMDs and big stoneflies. As word of good fishing gets out visits will increase to the easily approached river adjacent to the highway. If you venture there and note filled parking areas, walk upstream on the Big Horn Pass trail a few miles to find more tranquility in the river running through the sloping meadow.  Be bear aware!

If you live in the southwest corner of the Greater Yellowstone Area, why travel nearly 200 miles to fish the northeast corner of the park when the four major Fall River Basin streams (Bechler and Fall Rivers, Boundary and Mountain Ash Creeks), currently are in great dry fly shape and offer PMD, yellow sally, damsel fly, green and brown drake activity with oncoming terrestrial insect activity.  In addition, Beula Lake at the top of Fall River offers some of the fastest fishing in the area. All one needs to do is walk a few miles to enjoy the best waters in Fall River Basin.

Henry’s Lake, July 11th, 2020

There is some success to be found in water of  a moderate depth with small black or olive leech patterns. But now is the time to arrive early at creek mouths and springs to stake out your claim on water. The earlier the better because as the season advances and the lake warms, the more folks will be doing the same.  An intermediate line to present standard Henry’s Lake patterns at creek mouths will do the trick.

South Fork, July 11th, 2020

 

South Fork 4

Flow on the river is at great levels ( 12400 cfs at Irwin, 13500 cfs at Heise,  5000 cfs at Lorenzo) and water is cold but clearing up. Fish responding are where you find them!  There are plenty of sallies, some caddis, PMDs and big stone flies round, but fish seem to take them on an inconsistent basis with respect to location on the river. Nymph patterns, with and without a bead head presented over drop-offs seem to be the most consistent way to success.

Henry’s Fork, July 11th, 2020

Time to enjoy what is left of the great mayfly hatches on the upper river. Brown drakes and flavs are beginning to diminish.  Soon PMDs and speckled duns will make up the major mayflies. Caddis of many types will be around. But just around the corner terrestrial insects will rule the roost. Ants and hopper will be of major attraction to trout.

Look for the lower river to begin warming to the point that early and late in the day will be the best times to present caddis life cycle patterns as well as those for terrestrial insects. Also look for boat traffic to drop, but an increase in recreational boaters.

Small Streams, July 11th, 2020

 

Bitch Creek

Almost every small stream now offers good fishing. The number of these is almost beyond counting. From the Sinks Drainages (Big Lost River above Mackay Reservoir, Beaver, Birch, Camas, Little Lost, Medicine Lodge, Sawmill Creeks) on east to Palisades Reservoir and Salt River Drainages ( Big Elk, Bear, Crow, Jackknife, McCoy, Stump, SF of Tincup, Tincup, Creeks), all have something to offer the small stream enthusiast. Get in touch with us with questions on what to use, when to visit, etc., on any of these or others that are of interest to you.

Henry’s Fork, July 4th, 2020

We are past the peaks of the big stone fly and green drake activities. Now is the time on the upper river for flavs and PMDs during daytime and brown drakes during evenings. Look for a lot of folks being on Harriman East, especially using Wood road 16 to access the river during evenings. Because of the South Fork turning on crowds are thinning, but enthusiasts remain. This also applies to the lower river where good PMD and caddis activity remains, but the usual summer warming will begin any day.

South Fork, July 4th, 2020

The multiple hatch days on the Henry’s Fork have peaked. Now it is the South Fork’s turn! With the flow back to summertime levels ( 13200 cfs at Irwin, 13800 at Heise, 8000 cfs at Lorenzo)  all sorts of bugs are out. PMDs, green drakes, sallies, and salmon flies are out and up river at least into the canyon. Fish know what they are and are on them. The fun begins with figuring out which bugs are in the favor of trout at any given location on the river. So go with life cycle patterns for all those mentioned. Also include the old standard patterns. Word is out, so boat launch sites are crowded. So is the river road above Heise with boats being trailed to launch sites and shuttles being completed. You will see license plates from as far away as New Jersey and from as close as from here at home, but there is plenty of this great river for all of us.

Still Waters, June 30th, 2020

Chesterfield Reservoir continues to offer some of the best still water fishing in the area.  Try the upper end of Daniels Reservoir or the river channels entering Mackay Reservoir for other areas offering good fishing. Damsel fly life cycle patterns should be good bets on any of these.
