Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 12)

Henry’s Fork 7-6-19

The river in Island Park offers great late afternoon fishing during  caddis activity. Brown drakes are beginning to show up making evening fishing quite interesting.  Double nymph rigs work well in Box Canyon.  AM & PM PMD spinner falls bring trout to the surface.  Green drake are decreasing, but flavs increasing.

All these insects plus gray drakes are available to fish on the lower river where crowds are thinning a bit because fishing on the South Fork is  taking off.

Be aware of the two construction zones  on Highway 20 impacting travel to the river and beyond. We have given details on how to avoid hold-ups on the highway climbing Ashton Hill if you intend to fish in Island Park (use the Mesa Falls Scenic Highway).  The other significant construction zone on the highway,  the re-surfacing of the Lorenzo Bridge across the lower South Fork, impacts travel to the lower and upper river. Here the highway is down to two lanes for about four miles and accommodating the increasing traffic can mean delays of up to twenty minutes until piled-up traffic dissolves. Certainly, try not to be on this part of the highway during  “rush hour ” times

South Fork 7-6-19

Stoneflies are out up to Byington. Action begins during  afternoons.  Fish seem just as interested, for now, in sallies and mayflies. Try for these around riffles. Rubberlegs still work and so do super-X’s presented from out in stream towards banks.  Cast  super-x’s towards overhangs, then pull back into the river, or just let them drift  by overhanging vegetation.  Flow out of Palisades Dam has been raised a bit (to 1480 cfs) from Jackson Lake output.  In several days, look for flow to be ramped back to normal for this time of year

Yellowstone Park 7-2-19

Traffic conditions will slow you down going to any fishing destination in the Park.  To avoid these conditions on the west side of the park, try such as the Madison River near Baker’s Hole and Duck Creek.   Fall River Basin streams will not be crowded and are in good fishing shape. Because the Ashton-Flagg Road is passable, Beula Lake can be reached and will provide some of the fastest fishing in the Park.

Henry’s Fork 7-2-19

The lower river continues to offer the best and most consistent fishing. Some flavs, PMDs, a few goldens, caddis and even a few terrestrial insect attract fish.  Look for boating crowds to diminish as the South Fork fishing improves.  Weather conditions make fishing on the upper river a bit inconsistent.

Big Lost River 7-2-19

Flow out of Mackay Dam is about 750 cfs making for very tough wading.  Hatchery catchables have been stocked at just above Arco. We have no information to date on fishing conditions on the river above the reservoir.

Small Streams 7-2-19

All South Fork tributaries opened to fishing yesterday.  Of the Palisades Reservoir tributaries McCoy and Bear Creeks offer the best fishing.   Look for  small stoneflies, PMDs, and afternoon caddis activity to provide the best dry fly fishing on these, so have life cycle patterns for these handy.   Small traditional attractors, wet and dry, will also work well.  Little Warm River has good fishing for small brookies which make for good holiday fish fries.  Beaver and Medicine Lodge Creek are in good shape for fishing although we have little info on each so far.

South Fork 7-2-19

Palisades Reservoir is at full capacity, and in-flow is dropping.  Flow out of Palisades has been raised some in the last week. Now is 14000 cfs  (about the same at Heise, 7160 cfs at Lorenzo), which is  a bit above normal.

PMDs, green drakes and yellow sallies are emerging  upstream to Cottonwood making for improving dry fly fishing. Presenting flies around riffles is best strategy for doing so.  Big stoneflies are emerging up to Byington, but fish are just beginning to key on them. Rubber legs and streamers still working.

Fishing interest here is still well below that on the Henry’s Fork, but as fish become more interested in big stoneflies, look for boating crowds to appear.

Still Waters 7-2-19

Chesterfield Reservoir is providing some very nice ‘bows for those folks presenting damselfly life cycle patterns. Wind can interrupt this activity, and also make some dangerous conditions.

The Harriman Fish Pond is “mossing up” making surface and indicator fishing the most practical approaches.  As with Springfield Reservoir, seeking out channels between weed beds for using these methods is a best strategy.

The Snow Creek Road is open, but rough, at least to Teardrop Lake.

Still Waters 6-25-19

Some of our nutrient rich smaller waters are beginning to have seasonal aquatic plant growth ( “moss up”).  Hawkins Reservoir and  Springfield Lake are among these, but indicator and dry fly fishing is not impacted, especially on staying in/over larger channels between weed beds. Harriman Fish Pond, however, mosses up almost totally making channels tough to find under windy conditions. Chesterfield seems to be fishing well with damsel flies emerging in sheltered bays on wind-free, which also sport aquatic plant growth.  We have not received much information on Twenty-Four Mile Reservoir fishing success.
