Yellowstone Park, October 5th, 2021

The crowds seeking brown and rainbow trout encounters along the Madison River are increasing to the point that civility is suffering. The brown trout run into Lewis River Channel (between Lewis and Shoshone Lakes and below Lewis Lake) is going on and will peak after the park angling season ends at the first weekend of November. That event will also bring many anglers as will the late run up the Gardner River. The Firehole River now offers great fishing with BWO life cycle, white miller, and soft hackled patterns bringing the most interest from trout. If you venture there, watch the upcoming weather. Killing frosts are ongoing along Fall River Basin streams, but a well placed hopper pattern presented as naturally as possible can still lure a trophy trout out of the depths.

South Fork, October 5th, 2021

Flow out of Palisades Dam was dropped to 3940 cfs yesterday (now 4660 cfs at Heise, 2090 cfs at Lorenzo). These flows are great news for walk-in wade anglers through making the river safer and offering even more locations for such an approach. Unsettled weather coming up the next several days is another piece of good news for top water fishing as BWO and mahogany hatches will be at a peak. Trout will also be more receptive to streamer patterns during this period of unsettled weather. If you want to enjoy the beautiful fall colors along the South Fork, you’d better hurry. They won’t be around much longer!

Henry’s Lake, September 28th, 2021

Fishing seems to be picking up a bit for those presenting traditional Henry’s Lake patterns on intermediate lines. Weed growth remains thick and not yet decreasing. Water temperature is hovering close to 60 Deg. F, So significant cooling is needed to bring on the best fishing.

Southwest Montana, September 28th, 2021

Now that the gulper season has passed, the big attraction is the brown and rainbow trout run up the Madison River from Hebgen Lake. Still water fishing should pick up on such as Elk, Cliff, Elk,Hidden and Wade Lakes where fish are returning from the depths to cooling shallow water and cruise for feed items. Fly fishing shops are winding down the season with some good bargains on gear.

Still Waters, September 25th, 2021

With a protected minimum pool, Daniels Reservoir does not suffer the dewatering fate of many of our irrigation reservoirs. Currently Daniels offers some of the best still water fishing in the area. Indicator fishing to present midge pupa, small leech, and scud patterns after finding the taking depth around the many weed beds is most productive, Slow trolling or stripping streamer or leech patterns through deeper water brings some action.

Yellowstone National Park, September 25th, 2021

Crowds are beginning to arrive to fish the brown and rainbow trout migration out of Hebgen Lake and into the Madison River in the Park and into the Lewis River above and below Lewis Lake. The earliest possible arrival in the day at both places will result in the most tranquil fishing. Unsettled weather, such as predicted for the middle of the upcoming week, means more active fish and fewer fly fishers visiting. The best strategy for encountering these fish is to swing large streamer patterns deep through runs and holes using a sink tip line.

Henry’s Lake, September 25th, 2021

Thanks to cooling weather fishing is beginning to pick up on the lake. Some fish are being picked up from fairly shallow waters along the west shore. Use intermediate or #2 sinking lines to present traditional Henry’s Lake patterns in 4 and 6 sizes. Bill Schiess’s book ” Fishing Henry’s Lake” offesr several patterns for this time of the season.

South Fork, September 25th, 2021

Flow throughout the river is normal for this time of the season, but with Palisades Reservoir at only 9% of capacity more reductions are coming. The low volume means the river is cutting through silt beds giving some discolor to water coming into the river below. BWOs and Mahogany duns are active, but during these sunny days their numbers will be down with hatches concentrated in areas out of direct sunlight. Unsettled weather is predicted during the middle of the upcoming week, and such will intensify their activity.

streamer will bring action during evenings and early AMs.

South Fork, September 21st, 2021

Flow out of Palisades Dam has been reduced to 6560 cfs which is about average for this date ( Heise 7390 cfs, Lorenzo 4020 cfs, both about average). These flows open up a great number of walk-in wade locations, and the fall mayfly activity peak of BWOs and mahogany duns is ongoing up and down the river. We can suggest which locations might be the best to visit for enjoying fish responding to this activity.

The above picture shows another reason for visiting the South Fork as fall foliage colors are changing.

Henry’s Fork, September 21st, 2021

Here are excerpts from Dr. Rob Van Kirk’s Henry’s Fork drainage status report of today.

Headlines:  

  • Three-day precipitation totals ranged from 0.3 inch at Grassy Lake to 2.0 inches at Crab Creek, increasing the water year total to 82% of average.
  • Natural flow has increased by around 130 cfs since last Friday, while diversion has dropped by about the same amount.
  • At an average outflow of 236 cfs, Island Park Reservoir gained 415 ac-ft yesterday and is 42% full.

Details:

At 12 degrees F below average, yesterday’s mean temperature was the coldest since May 10. The daily minimum was the coldest since June 11. With complete data in hand, Saturday-Monday precipitation totals ranged from 0.3 inch at Grassy Lake to 2.0 inches at Crab Creek. Other stations receiving 1 inch or better were Grand Targhee, Pine Creek Pass, and Lewis Lake Divide. The watershed total was 0.86 inch for the three-day event. That was enough to move water-year total precipitation from 80% of average to 82% of average. If the forecast for dry weather holds for the next 10 days, total precipitation for the water year will end up 81% of average. That will rank 6th lowest since 1989, the lowest since 2007, and around 2.5 inches less than in 2016. Dry conditions and above-average temperatures are expected for the next week.

Natural flow continued to increase yesterday in response to the weekend rain but is still only 73% of average for the date. For the water year, total natural flow is76% of average, which is about where it will end up once the water year is in the books next week. Meanwhile, diversion has decreased by around 9% since last Thursday, although a few canals increased diversion a little yesterday. Streamflow in the lower Henry’s Fork peaked yesterday afternoon at around 400 cfs above its irrigation-season target and is dropping this morning. The effect of yesterday’s outflow decrease from Island Park Reservoir has not yet reached the lower watershed. After things settle out in another day or two, I expect streamflow in the lower Henry’s Fork to drop back closer to but still above the target flow.

At an average outflow of 236 ac-ft, Island Park Reservoir gained 415 ac-ft yesterday and is 42% full, compared with 46% full on average and 17% full in 2016. Although fill rate will decrease a little as the effect of the weekend rain subsides, I expect the reservoir to end the water year at around 60,000 ac-ft (45% full), which would be right at the 1978-2020 average, despite a water year with natural flow at only 76% of average.
