South Fork Fly Fishing Report

South Fork Fly Fishing Report

The section of the Snake River which flows out of Palisades Reservoir into Idaho is what’s referred to as the South Fork.   The South Fork of the  Snake River offers extremely diverse fly fishing experiences. Whether sight fishing to picky fish, targeting trout in the shallow riffles using small PMD’s and caddis,  or twitching stoneflies and big hoppers along the river banks, the South Fork offers all types of fishing experiences.

The valley stretches offer a broad river with many side channels and braids that provide great fishing in the riffles. The canyon stretch is 26 miles of wilderness. Cutthroat, rainbows and browns call this river home and can grow quite large.

Given the right conditions the South Fork can come alive with the salmon fly hatch at the first of July, while the fall fishing on the South Fork can provide some of the best action.

As summer moves into mid- August, the fishing on the Snake has continuously improved over the past weeks. The flow rate at Moose has held around the 3,000 CFS mark, which in combination with our warm weather has produced good numbers off hoppers on the river. Anglers can catch numerous fish between the 8-14" range, and many fish in the 15-20"...... read more

The fishing on the Snake has been very productive this past week with both beginners and experienced anglers having great success. While many of the fish are smaller in size, they more than make up for it with their numbers. With that being said, we are beginning to see more and more big fish landed every day. At this point in the summer the fish...... read more

Memorial Day weekend turned out to be a good one. Plenty of nice weather, and a lot of good fishing for Yellowstone’s opening weekend. Some of our guides headed up to Yellowstone to fish the lakes, and the Firehole River opening day. We had great reports from both water systems.  The Firehole was a little late with bugs hatching due to the cold...... read more

  Summer is here and in full force. All area rivers in Jackson Hole are fishing and the boat ramps are busy.  Temperatures in the valley have been warm and mostly stable in the high 80’s during the day peaking at around 94 in some areas and cooling down in the evenings to low 50’s.  This has gotten the bug activity in action...... read more

Jackson Hole Fishing Report 5/26   The Snake's run off is well on its way with flows being measured at 6930 cfs in Moose this afternoon.  If the weekend forecast holds true flows should increase even more as warmer temperatures will speed up the snow melt process. There are still fishing options in the area. The South Fork of the...... read more

Fishing Report for week of 2/9 The temperatures are still in the 40’s, and there is no evidence telling me that is going to change through the rest of the week.  This warm spell has been giving us some unusual good February fishing.  A lot of anglers have been fishing everywhere from our local Snake river, to the Henrys, and the South...... read more

After a week of steady water reduction on the Snake we are now at winter flows for the foreseeable future. Due to heavy rain in recent weeks the winter flows will now stop on the 8th and will stabilize around 450 CFS. With the larger reductions already having taken place last week, fishing has returned to normal fall conditions. The colder...... read more

Well we couldn't have asked for a much better September than this one. Fishing has been great and favorable conditions the next few days suggest we still have some time. Although we encountered a lot of rain and colder temperatures throughout August, September has been great with temperatures rising up to high 70s in the afternoon. Sunny skies...... read more

Trout Fishing South Fork of the Snake River

July 9th, 2014

The last couple weeks have been very warm, but looks like we could get some cooler temperatures with some afternoon storms in the forecast. This has accelerated the snow melt, but has also made current fishing conditions tough. Just under the Jackson lake Dam flows have increased up to 2520 CFS. With the increased flows and warm weather the...... read more

The Season is upon us. Clear skies and warm weather is expediting the snow melt. We have still got a couple of weeks till the Snake is ready, but by the end of the month it should start fishing. We've had some positive feedback from some of our guides recently.  Although clarity is not optimal, we have had some success with tandem nymph rigs...... read more

Little Girl With Fish

June 27th, 2014

The cold weather from last week stalled the run off, but with temperatures in the high 70s throughout the week expect to see it pick up again. The Flows have increased around Moose to 7220 CFS and we should see the Snake start to get muddy again. Below the Jackson Lake Dam flows have been stable at 1800 CFS. Although visibility is great, the...... read more

The Snake River is still high, and muddy while our run off is still in full swing. The best stretch on the Snake would be our tail water stretch dam to Pacific creek, where the flows out of Jackson Lake is at a steady 1,800 cfs.  The water is not clear, but is certainly not muddy, making it a decent option in the Jackson Hole area right...... read more

The Bureau of Reclamation raised the flows out of Palisades Dam today to 15,500 cfs with plans to go to 18,500 cfs on Sunday.  This is to mimic a natural flush during the spawning season, so the wish for stable flows for the next week are not coming true.  Stay tuned, when they stabilize flows and the water temp warms up a bit, it will be a...... read more

June 4th, 2014

Currently flows out of Palisades Dam are right at 14,000 cfs, which is a very fishable level, some even argue that this higher flow is better than a lower flow.  It creates more riffles and skinny water for the fish to spread out and feed on small mayflies when they start hatching later in the summer.  The river has been stable at 14,000 since...... read more

We have enjoyed some rewarding fishing on the South Fork this season with more experienced anglers, as the river has been demanding of more technical fishing, and we continue to see some good action.  Streamer and nymph fishing has been most productive the last couple weeks with reports from our guides and friends that there are some sizable fish...... read more

The South Fork of the Snake in Irwin, Idaho is shaping up nicely.  Some much needed rain in the last part of May is great news for our water situation.  The flows out of the Palisades Dam are currently at 11,000 CFS and the forecasts show it stabilizing around the 8,000 cfs mark by Friday.  This is ideal flows for the river, bugs and fish. ...... read more
