Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 42)

Henry’s Fork August 2nd, 2022

Throughout the river early AMs and evenings remain the best fishing. Thinking of trying the river during weekends? Be ready to share it with recreational floaters.

Headlines from Dr. Rob Van Kirk’s Henry’s Fork drainage report compiled yesterday are below.

 Headlines:

  • The daily maximum temperature yesterday was the warmest since July 26 of last year, but cooler temperatures are expected over the next week.
  • Diversion and natural flow both dropped a little yesterday, increasing stream flow in lower Fall River and lower Henry’s Fork.
  • At 240 cfs, current Crosscut Canal delivery to the Teton River is meeting irrigation demand and stream flow targets there after exchange well pumping was reduced a few days ago.
  • Island Park Reservoir is 65% full, compared with 67% full. Outflow reductions are possible this week, depending on stream flow and diversion response to rain and reduction in outflow from Grassy Lake.
  • Flow out of Grassy Lake Reservoir will be reduced resulting in a 100 cfs flow reduction in Fall River.

Yellowstone National Park, July 30th, 2022

The Park has opened the road from Tower Junction to Slough Creek to auto traffic. The road from the Northeast Entrance ( Silver Gate) to Slough Creek remains closed to auto traffic.

Beula Lake

Right now Beula Lake offers some of the fastest still water fishing in the park with speckled dun and damsel fly activities bringing on big time cutthroat trout responses.

Still Waters, July 26th, 2022

Reservoirs owned by irrigation companies are being drawn down to satisfy agricultural demands. Fish in such as such as Chesterfield, Twenty-Four Mile, Treasureton and Hawkins Reservoirs will move to cooler, deeper water. Fish in smaller, shallower still waters not subjected to irrigation draw down such as Horseshoe and Teardrop Lakes and the Sand Creek Ponds and the Harriman Fish Pond will become less active during daytime hours. For any of these still waters fishing is most successful early in the day after surfaces have cooled through radiating heat away during night time.

So the old saying “The Early Bird Gets The Worm ” applies to fishing still waters during the summer dog days!

Henry’s Lake, July 26th, 2022

Creek mouths and springs are the only good places for action these days. That means there will be plenty of other Henry’s Lake fishing enthusiasts at these locations.

Fisheries managers and much experienced Henry’s Lake anglers tell us that Utah chubs have resided in Henry’s Lake for a long time. They were discovered there years ago. The Idaho Department of Fish and Game has completed some research on the interaction of these undesirable species on resident cutthroat trout and published the results which are fascinating.

South Fork, July 26th, 2022

Flow out of Palisades Reservoir remains constant and right at the historic level throughout the river.

There is no significant change that we suggest with respect to fishing strategy since our report of July 23rd except that stream-side terrestrial insect populations are increasing during these “dog days” of summer. Consider that when you assemble a suite of flies for the next visit to the river! Mutant golden stone flies have not begun to emerge.

Henry’s Fork, July 26th, 2022

Other than spinner falls and caddis activity, we are in the time of the season where terrestrial insects are taking over as a major food form for trout.anywhere you fish the river. Be sure you have patterns for such in that fly box. And as time passes through summer, ant patterns will become of increasing effective among these.

Here are headlines from Dr. Rob Van Kirk’s Henry’s Fork drainage water report filed yesterday AM.

Headlines:  

  • Warm, dry weather will continue for the rest of the week.
  • Natural flow stayed constant at 63% of average yesterday, while diversion continued to drop and is 88% of average.
  • Outflow from Island Park Reservoir was reduced by 100 cfs yesterday, and additional reductions are likely over the next week.

South Fork, July 23rd, 2022

Flows are right where they should be for this time of year (!2400 cfs at Irwin, 12200 cfs at Heise, cfs at Lorenzo). Golden stone flies are still around in the lower canyon. Riffles are producing especially when medium sized nymph patterns with and without bead heads are presented.

Small Streams, July 23rd, 2022

The Teton River in the basin is fishing well for dry fly enthusiasts with PM caddis activity and spinner falls providing late in the day action. PMDs, sallies, and a few green drakes and golden stone flies are around. Our comments on recreational boating traffic on the Henry’s Fork apply to these waters as well. Dry fly fishing in the canyon via the Bitch Creek Slide, Felt Dam, Spring Hollow and the dam site is also good, with streamer patterns also producing. Be fully aware of rattlesnakes if you venture past stream-side locations in the canyon.

Palisades Reservoir tributaries (Bear, Big Elk, McCoy Creeks) and Palisades Creek are in good fishing shape with caddis life cycle, terrestrial insect and traditional attractor patterns working well.

Yellowstone National Park, July 23rd, 2022

On July 21st Yellowstone Park opened the road from Tower Junction to the Northeast Entrance for foot and bicycle traffic only. This means the Lamar River, Pebble, Slough and Soda Butte Creeks and Trout Lake will have little if any fishing pressure.

Meadow stream fishing enthusiasts may now switch interest to Fall River Basin streams ( Bechler and Fall Rivers, Boundary and Mountain Ash Creeks ) which are now more quickly approached than the best locations that those in the Lamar River drainage offer.

Henry’s Fork, July 23rd, 2022

Box Canyon, Warm River to Ashton, and Ashton Dam to Chester backwater sections are seeing a big increase in recreational floaters. The peak of this activity is usually from late morning to late afternoon. For the latter two locations, this time stretch coincides with the slowest fishing success. Minimize your interaction with these folks by fishing early AMs and during evenings when fishing success is much likely best during these warm days. Everywhere on the river, bank side terrestrial insects are taking over as being a most important food form for foraging trout. Carry fly patterns that simulate them and concentrate your presentations to banks above good holding water.

Here are headlines from Dr. Rob Van Kirk’s Henry’s Fork drainage water report compiled yesterday, July 22nd.

Headlines:  

  • Dry weather with temperatures 2-4 degrees F above average is expected to continue for the foreseeable future, as drought redevelops along the northern edge of the watershed.
  • Current USGS gage readings are around 80 cfs higher at Island Park and 300 cfs higher at Ashton than actual stream flow.
  • At an outflow of 1423 cfs yesterday, Island Park Reservoir is 77% full, right at average for the date.
  • No large changes in irrigation-system management are expected for another week or so.
