Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 2)

South Fork 7-9-10

From Bryce Oldemeyer, South Fork Initiative Project Manager, HFF: Discharge from Palisades Dam was reduced 1,000 cfs this afternoon (7/8, 2pm) and will be reduced another 1,000 cfs tonight. Discharge from Palisades Dam will be 13,300 cfs tomorrow morning. Dependent on irrigation demand, small decreases to Palisades Dam discharge may be made later this week.

Riffle fishing from PMD and yellow sally activity offers best action by early afternoons.  Beforehand use your favorite small beadhead nymph patterns there.  Rubberleg patterns may also work here during the early hours. Stonefly hatch is below Cottonwood and has been doing a great job of taking boats from the lower Henry’s Fork.  Don’t forget the tip of slowing down your boat and pitching super renegade patterns underneath or just in front of  overhangs and retrieving as you drift on by!

Yellowstone Park 7-9-19

The Firehole is beginning to warm enough that the revival chances of  C&R fish diminish each day.   Fishing on the Madison depends mostly on quality of the PMD emergence. Because of the removal actions last year, the Gibbon above Virginia Cascade is essentially fishless. Meadow sections on the Gibbon below, however, are offering evening brown drake emergences. A more sporadic brown drake emergence is ongoing on Duck Creek.

Northeast side streams  (Slough, Soda Butte, Buffalo Fork, and Pebble  Creeks and Lamar River) are beginning to drop and therefore need more time to offer good fishing.  Trout Lake is “mossing up” making dropper and surface fishing the only ways to go.

Fall River streams are under going erratic flows because of weather and snow remaining on Madison and Pitchstone Plateaus above.  This is mosquito season in the basin (and at many other park locations), so dress accordingly. Beula Lake offers very good fishing especially for those willing to carry a flotation device into the lake. Speckled dun and damselfly activity there means life cycle patterns will work. So will small leech and bead head nymph patterns.  The same applies on a smaller scale to Riddle Lake with a shorter walk  (about a mile) off the South Entrance Highway

Streams of the upper Gardner River drainage, such as Glen, Indian, and Obsidian Creeks, etc. are now great places to take entry level fly-fishers.  Small but aggressive brook trout make up the fishing here, and the best action is away from the roads.

The Upper Yellowstone River (above the Falls) opens July 15th.  Below Grand Canyon the river is discolored from Lamar River inflow, but offers some success for those presenting streamer, woolly bugger, and rubber leg patterns.

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.
