Eastern Idaho Fishing Report 7/14/23

Henry's Fork: The current flows out of Island Park are 1,370 cfs. Flows have increased recently due to irrigation demand and may continue to increase with the rising temperatures. The upper HF in the Box Canyon area has been day to day, one day it will be fishing decent and the next it has been tough. Nymphing is going to produce the best using a duracell or a dry dropper rig with a golden stone and a pt leggy aka "bowling ball" below. In the Railroad Ranch there are pmd's still going, drakes are pretty much done. Best fishing will be in the mornings on pmds and caddis, in the evenings with flavs. The Warm River-Ashton section is fishing okay. We are seeing caddis and yellow sallies. Using a dry-dropper rig should produce. A large chubby chernobyl pattern in gold or peach color will work for up top and then below you can try using an olive bullet #14, yellow sally nymphs, or olive hot spot #14. Fishing has been best in the mornings, tends to slow down in the afternoon. Flows out of the Ashton reservoir are 2,380 cfs. The lower Henry's Fork is fishing well. We are

Boise River & Owyhee River Fishing Report 7/14/23

Boise River In-Town: Flows in town are still high and fast, wade cautiously. Streamers and nymphing are the go to. Attractor style nymphs size 16 - 20, like fire starters and hares ears. Midge nymphs are a safe bet as well in black and red like zebra midges. Big articulated streamers have been finding fish in olive, black, and white. Woolley Buggers and Dungeons have been working well. South Fork of the Boise: Flows are currently 1,230 cfs. Still high, but floatable. Salmonflies are phasing out. Goldenstones have been spotted. A hopper dropper rig should produce. For droppers using a fire starter or duracell nymph will work or even using rubber legs for heavier nymph rigs will work too. Owyhee River: Fishing is really on! Prospecting the usual midge nymphs size 18-22. Hopper dropper is finding fish in riffles. Pmds and caddis really coming alive in the afternoon. Zebra Midges, Split Case, San Juan Worm for nymphs. PMD RS2, Stacked Hackle, Sparkle Dun, X Caddis for dries. Have fun and stop by TRR Outfitters in Eagle or call (208) 939-6065 to stock up on some flies, purchase your Owyhee fishing license, or book a guided fishing trip. Owyhee River

Eastern Idaho Fishing Report 6/2/23

Henry's Fork: The current flows out of Island Park are 1,140 cfs. We are seeing salmonflies flying on the lower sections. If you lift up rocks you will find a ton of salmonfly nymphs. A dry dropper should produce fairly well. Henry's Fork salmonfly #4 as the dry fly with a Pat's black rubber leg #8 or #10 below should do the trick. Don't be afraid to fish off the banks a bit. There are have been some fish eating caddis as well. Feel free to stop by our Ashton Fly Shop for a daily report, 1051 Hwy 20 Ashton, ID 83420 208.652.3008, open 7 days a week 8 am – 5 pm. South Fork: Flows are currently at 14,000 cfs. Nymphing is going to be the most productive with eggs, SJ worms, rubberlegs, and zebra midge variations. Streamers and leeches will also work. Water clarity is improving, the best fishing and conditions will be in the upper sections but canyon is starting to shape up. Stop by our Driggs Fly Shop 76 N. Main Street Driggs, ID 83422 208.354.1200, open 7 days a week 8 am - 5 pm. Teton

Boise & Owyhee River Fly Fishing Report 6/2/23

Boise River In-Town: The Boise River in-town is still high and is unsafe to fish. South Fork of the Boise: The South Fork of the Boise River is open to fishing but flows are currently around 4,400 cfs which are too high to safely wade. Owyhee River: Flows are great at 200 cfs. Primary hatches consist of midges and BWOS. Caddis are present to varying degrees as well. Dry fly opportunities have been spotty but are there if you are trying to find fish looking up. Nymphing as usual remains the most productive (juju baetis in blk or purple #18 or #20, split case pmd's, olive and blk zebra midges) and streamers are always an option. Midge and BWO hatches should continue to increase in volume and become more consistent. PMDs should also start making more of an appearance as the weather heats up. Have fun and stop by TRR Outfitters in Eagle or call (208) 939-6065 to stock up on some flies, purchase your Owyhee fishing license, or book a guided fishing trip.

Eastern Idaho Fishing Report, 5/19/23

Henry's Fork: The current flows out of Island Park are 1,260 cfs. Fishing has started to improve but you will still need to dig deep and work hard to catch some fish. You are going to want to have zebra midge variations; black, red, etc., olive bullets #16, toddlers olive and black #14 or #16, and rubber legs. Seems like the best dry fly activity is in the early evenings (5-7pm) with peacock caddis. Streamers may also work in black & olive. Warm River is still high and a little off color but is starting to show some life again. A few salmonflys were spotted flying around the other day. I would be sure to have some salmonflys, March browns, and caddis on you for those fish looking up. I would also have some rubber legs and olive bullets. Henry's Lake has been producing. Small black or red chironomids, small black leeches, and large white articulated steamers have been working when stripped super slow. Be sure to stop by our Island Park Fly Shop for lake flies and our good friends at Drift Lodge to pick up anything you need for Henry's Lake. Feel free to stop by our

Eastern Idaho Fishing Report, 5/5/23

Henry's Fork: After a long winter filled with lots of snow, the thaw is on, and the snow is melting quickly. The current flows out of Island Park are 624 cfs. It is tough fishing out there right now. With the warmer days we had at the beginning of the week the river is up and off color. At Warm River, there are plenty of Mother’s Day Caddis coming off, but not many heads up, using rubber legs and smaller bead heads will be the most productive but be sure to have some peacock caddis and parachute Adams on you in case you spot a rising fish. From Ora to St. Anthony there are blue wings and midges coming off, but again, not many rising fish. Subsurface you will want to focus on zebra midge variations; black, red, etc., olive bullets #16, toddlers olive and black #14 or #16, rubber legs, split case bwo’s #16 or #18. Streamers may also work in black, olive, white, or black/olive. With rain expected to move in this weekend, stay safe and enjoy!

Boise River Fly Fishing Report – May 4, 20187

Boise River – In Town Fishing Report Flows remain a little high, but they are dropping. If you do decide to fish, use caution where you get in and out, but it’s fishable. Streamers can work well when the water drops this time of year.   So try throwing Coffee’s sparkle minnow, Sculpzilla, Shiela’s sculpin, or your favorite sculpin pattern in natural colors. Best time of day is in the evenings. Mid-day will be good too if you’re nymphing. Try a jig-head pheasant-tail, zebra midge, prince nymphs, or copper johns. The river is still pretty high, and the water is cold, so use extreme caution and be careful! The South Fork of the Boise is closed until Memorial Day weekend.   Stop by or call our Boise Fly Shop for up to date information on where to fish and what to use.

Owyhee River Fishing Report – May 4 2018

Flows are stable at 180 CFS. We think it will stay at this flow or even drop a little due to the non-existent snowpack in the Owyhees. Whatever storage they have they need to save for irrigation this summer. The steady flows mean that PMD’s are just around the corner. We’ve seen a few adults, but we’ve seen mostly caddis and also midges popping in the late afternoon to mid-evening. Blue-winged olives are still around but with the warmer temperatures will slowly fade away. If you do not see anything on top, try a dry-dropper setup with a caddis, parachute Adams, skwala, beetle, or any stimulator pattern on top. Subsurface you’ll focus on variations of zebra midges; black, red, etc., small pheasant tails #18-20, soft hackles, or little baetis nymphs #18 & 20. Streamers can be productive too; white, olive, white/black. Have fun and stop by TRR Outfitters in Eagle to stock up on some flies and to purchase your Owyhee fishing license.

Henrys Fork, SF Snake, & Teton Fly Fishing Report – May 3, 2018

Finally!  We are progressing into spring and as most of you, I am chomping at the bit to get out there more often.  In most areas in the West, we are definitely in the middle of runoff and many rivers, both large and small, are high and off color. That being said, the name of the game right now is the Henrys Fork of the Snake River.  Although the water has been increasing both out of Island Park Reservoir and Ashton Dam, the fishing has been fair to good.  Recent reports show large caddis flies and blue wings popping around 1 pm to 2 pm.  The good news regarding is that it usually turns on early in May, and the Henrys Fork Salmon fly hatch is right around the corner. The Teton River has experienced an early runoff as well and is flowing high and off-color.  The good news is that if the warm weather continues, we will conclude the spring runoff earlier this year than in many previous years.  There are people floating and wading the Teton and the ticket has been large flashy streamers and large flashy nymphs like bright pheasant-tails and pink and red worms. The South
