Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 15)

Small Streams 9-8-18

Bear Creek reduced

Smaller streams are now mostly at base level. That means concentrate fishing efforts on deepest downstream water. Terrestrial insect patterns will be effective, even for days after a killing frost. In the smaller category Bear, Birch, Palisades, and Big Elk Creeks currently offer the best fishing.  Larger small streams offering good fishing are the Teton River throughout, lower Blackfoot River (still a bit high with nymphing and presenting streamers best ways to find action), and Warm River (BWO, hopper, and caddis activity).

South Fork 9-8-18

03-12-09 South Fork 010

Flow out of Palisades Dam has been stable for several days at around 8500 cfs.   Expect flow to drop further soon. Hopper fishing is great up and down the river, and evening caddis activity continues to attract trout.  Some mutant stones are present, but lower water would help their numbers. Mahoganies and BWOs will begin to be important soon as we cool off.  The same will apply to streamers presented during low light conditions.

Not much change here with AM trico swarms, daytime terrestrial insect activity, and evening caddis activity. This applies to just about the entire river.   As browns begin to migrate in the lower river streamer fishing will be increasingly effective, especially during low light conditions.  The lower river is cooling so look for tiny BWOs to become active enough to interest trout.

It sure seems like a repeating theme and it applies to all meadow streams in the park. AM trico activity and daytime terrestrial insect activity are the best items for successful fishing. With cooling air temperatures look for fishing on the Firehole River to improve. BWO life cycle and white miller patterns will bring success. The autumn run of browns and rainbows out of Hebgen Lake into the Madison River in the park has begun and will increase as we move through the next two months.   Presenting big soft hackles and streamer patterns are the best way to encounter these fish, and best results will be during overcast conditions.

Bitch Creek 9-25-13

With school now in session, most vacations over, and cooling daytime air temperatures, look for a decrease in recreational floaters and boaters on the Teton River in the basin and even through the canyon. That signals a return to tranquil daytime fishing.  For the river in the basin successful fishing is tied to Early AM trico activity and terrestrial insects during daytime hours. Big attractors (ie chubby chernobyls) will always be effective in the canyon reach this time of year.

Terrestrial insect season is going on up and down the river. Exceptions include AM trico mating-spinner falls and evening caddis activity.  PMD activity is greatly diminished and speckled duns are important only on slow river reaches such as the Flat Ranch and Harriman State Park.  When cloudy days arrive streamer fishing will be more effective during mid-day rather than just around first light and twilight.  Tiny BWO activity on the lower river is several days away.

SF With Baldy 2 (640x480)

Flow out of Palisades Dam was reduced to 8550 cfs  (same cfs at Heise, 2770 cfs at Lorenzo) Tuesday. This will make for more walk-in wade fishing locations and increase the mutant golden stonefly emergence.

South Fork 4

No change in flow here, currently flow is a bit higher than the average for this time of year, so reduced flows are coming up as irrigation season winds down. Stick to what we suggest in the  8/25/18 report for the South Fork. Mutant golden stones have moved into the lower canyon, but hopper fishing there seems more effective.

For all Fall River Basin streams fishing success boils down to presenting trico life cycle patterns during AM hours and terrestrial insect patterns afterwards.  In slower waters speckled dun life cycle patterns can be effective.  Mosquitoes are mostly gone, but horse flies have taken over as top rated pest. Expect fishing success in all meadow reaches to slow during mid-day hours.   Same applies to all such streams in the Park and outside.
