Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 25)

Henry’s Fork 7-13-19

Lower river is definitely warming, so we suggest fishing in the early AM when spinner falls provide some action.  Presenting streamer patterns, especially during early in the day overcast conditions, can bring out some large trout.  Fishing the upper river is more consistent with continuing AM and PM spinner falls and afternoon caddis activity. Look for mayfly populations to begin diminishing from the spring-early summer peak and for bank side terrestrial insects to increase in number.  Depending on weather (mostly thundershowers and resultant winds ) some good fishing can be found in less crowded spots along the river such as the Coffeepot area, the Tubs area, and the Flat Ranch preserve.  Spinner falls, afternoon caddis, yellow sallies, diminishing PMD and golden stones and increasing terrestrial insects will provide interest from trout. From now through Labor Day expect to share the river in Box Canyon and the Big Springs-Mack’s Inn section with floating recreationists.

Small Streams 7-9-19

The choice here is almost endless. Do you want some tranquility? Again your choice is almost endless.  Contact us on which may be best based on current information. Do you want to fill a 25-fish legal daily limit of brook trout for an upcoming fish fry? Best candidates for doing so are Little Warm River, Robinson, Sawmill, Beaver, Cottonwood, Trail, and Partridge Creeks.

Big Lost River 7-9-19

Flows between 600-700 cfs coming out of Mackay Dam make for treacherous wading below.  If flow were cut in half, it would be safer for enjoying the golden stone and western green drake activity soon to come on. We still have no info on the river in Copper Basin, but USGS water flow gages tell us that Basin stream flows are are about normal.  So that alone suggests that good fishing should be available.

Henry’s Fork 7-9-19

On the upper river weather determines intensity and fly-fishing success during the PM brown drake emergence.  Try to use good weather evenings for best chances. Recreating boaters are coming to Box Canyon, and they have the same right to use the river as anglers.   Their numbers peak during mid-day, so to minimize interference consider early AM, or late afternoons for your visit here.  AM and PM spinner falls, afternoon caddis activity, PMD,and beginning-to-diminish flav activity give the best chances for success in the Last Chance-Harriman section.

PM caddis activity and the same spinner falls as on the upper river provide good fishing on the lower river.  Green and gray drakes provide action, but begin fading out there as the river warms.  Another bit of good news is that the South Fork stonefly hatch has transferred many boat away from this part of the river.  This week will see rising air temperatures on the lower river and therefore rising water temps.

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.
