Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports

South Fork June 5th, 2020

Flows on the South Fork jumped up to 20,000 cfs today. At these flows your only real option is nymphing with big indicator rigs. There are much better options in the region right now to fish though, give us a call and we can get you squared away. If you are dead set on fishing the South Fork, be extremely careful!


Big Lost River, June 2nd, 2020

Flow out of Mackay Dam is on the increase and currently at around 450 cfs. This flow makes for tougher wading, which will become tougher as flow increases due to irrigation demands and because Mackay Reservoir needs room for upcoming run-off.


Small Streams, June 2nd, 2020

We do not have a lot of fishing information on these right now because so many folks are chasing the Henry’s Fork stonefly hatch. Warm River is a good candidate to try with caddis and BWO life cycle patterns  bringing success. The Teton and Fall River drainages are in run-off mode, and the lower Blackfoot River is running high because of downstream irrigation demands.


Henry’s Fork, June 2nd, 2020

Most boat traffic now is on the Warm River to Ashton section of the river. But the most fish responding to the stone fly hatch is from Riverside Campground down to Bear Gulch with activity in Box Canyon coming on.  Look for boat traffic on these sections to be on the increase.   Give the lower river some more days before fish there begin looking for stoneflies again after digesting those from the early days of the hatch.  Fall River is putting in much run-off water. This will impact fishing below Chester Dam in the negative.


South Fork, June 2nd, 2020

Flow out of Palisades Dam was increased to 14900 cfs last night.  This change will impact riffle fishing more than doing the same in other features of the river. So look for a decrease in BWO activity along the river.


Still Waters, June 2nd, 2020

If you are looking for small water tranquility, here is some information to help you decide on destinations. The Horseshoe Lake Road  (off the Cave Falls Road) is open, and rainbows and grayling are present in the lake.. The Harriman Fish Pond has easy access and has holdover rainbows.  The road to Teardrop Lake is drying out.   The Forest Service suggest letting this go to completion before  going to the lake in order to minimize ruts and chuck holes.


Henry’s Fork, May 30th, 2020

The big stonefly hatch peak has passed the  river below Ashton Dam.  These bugs are just beginning to fly in number in the Hatchery Ford area. So the event is on its way to Box Canyon and beyond.  For the river below Ashton Dam wait a matter of days and depending on weather and water temperature, fish will have digested their bugs and be looking for more until the next big hatch ( green or gray drakes?) comes along.


Yellowstone Park, May 30th, 2020

We have received 2020 Yellowstone Park fishing licenses and regulations. All Montana entrances to the Park open Monday, June 1st. This will make it easier to get to the Firehole River rather than going via the south entrance. The Firehole, being the usual early season Park hot spot, is likely to be well attended.  But well placed BWO & caddis life cycle patterns, soft hackles (partridge & olive, partridge & amber) will bring action.  Look for that action to improve if showers threaten.


South Fork May 28th, 2020

Flows on the South Fork were bumped recently from 11,000 to 13,800. Fishing has been very good on the river both with nymphs and streamers. Recently blue winged olive hatches have brought fish up when conditions are right. We get a lot of questions about the water clarity this time of year and even though the water is typically “green” because of snow melt up high, it is very fishable! Give us a call at the shop or stop by next time you are around and we can get you squared away.
