Thermopolis Fishing Report, Bighorn River Wyoming Guides:
3/3/17- Your up to date fishing report for the Bighorn in Thermopolis WY. The Bighorn is a great option to get out of the wind during the spring. The fishing has been excellent and the wind has been pretty low, especially in comparison to the Reef. Most fish caught are between 17-21 inches. We have been catching both Brown’s and Rainbow’s. Sow bugs and midges are the food of choice right now.
2/23/17- The Thermopolis fishing report for the Bighorn in Wyoming is excellent right now! Here it is directly from one of our guides.
Water was a little higher than normal for this time of year. So wade fishing was a little limited still had good access though. Fish were concentrated in slow water with at least a 3 to 4 ft depth of deeper. Yesterday was partially cloudy with some dry fly opportunity available through out the day on midge patterns and the last hour to hour and a half of day light had some decent opportunity too. Midge hatches are starting to get really good and fish really keyed in on them in the late afternoon to early evening. Nymph fishing was outstanding using a size 16 hot beaded soft hackle Ray Charles and a tan Ray Charles with a fire orange thread head in size 16 through most of the day. I used a grey Charles and my version of the mayhem midges and late afternoon to early evening the midge was outstanding. Depths and weight ranged from a single #4 shot at 4 to 5 ft all the way to a BB at 8 1/2 ft. Got a total of about 60 fish hook between 2 anglers for a full day. With about 25 to 35 landed. Caught rainbows browns and 2 cut throat averaging 18 to 20 inch with some pushing 23 to 24 inch. Some fish are making beds so careful when walking. Males are getting very nice color already and some females are full of eggs so handle with care. Seem lines fished well along with shelf lines. Best way to fish about shelf right now is to throw close to the shelf and drop in the deep water fast. Most fish tucked in with in 20ft of the ledge was able to pick up some through out the whole run of the deep water though so fish as much deep water as possible after a shelf. Water clarity was amazing with at least 6 ft visibility with right lighting could see as deep as 8 to 9 ft or possibly more. Over all river bottom was very clean didn’t really pull up any moss on flies the whole day.
11/02- The dry fly fishing on the Bighorn has been epic. The moss has made it hard to nymph and little difficult to streamer fish but it can be done.
10/23/16- The dry fly fishing on the Bighorn in Thermopolis Wyoming has been excellent! Fish are podded up and willing to eat mayflies. There is floating moss making nymphing and streamer fishing somewhat difficult but not impossible.
10/3/16– Fishing has been good on the Bighorn. Expect opportunities to catch fish on nymphs, streamers and dries. There continues to be floating moss so with nymphs look to fish heavy enough to quickly get your flies into a feeding zone. Good bugs have been San Juans, Sow bugs, Ray Charles, Scuds and Midges. With dries, look for pods of fish throughout the day. They have been eating size 16 and 18 parachute Adams patterns and some Trico patterns. With steamers expect moss, but it’s still an effective way to fish. Good patterns have included Sparkle minnows, bow River buggers, and a variety of Sculpin patterns.

Bighorn River Fishing Report Thermopolis Wyoming-July:
7/14/16- The yearly summer Bighorn flush is happening today. This will help clear out much of the moss. They are bumping up the flows to 3200 cfs around 9pm and should be back down to normal flows by 10 am tomorrow morning. In the last week we have seen pretty good pod’s of fish up eating Trico’s.

June Bighorn River Fishing Report Wyoming:
6/25/16- The bighorn is down to 4000 cfs and is really mossy right now. There is a lot of floating moss all through out the water column. Each cast with a nymph rig will moss you up and every other cast with a streamer rig. Big fish can still be caught holding along the banks but it takes patience cleaning of the moss.
6/12/16-The Bighorn Flows are back up to 6000 cfs. The reservoir is 96% full so the flows will probably get higher before they come down. Fishing has been good but definitely more difficult than lower flows. Fishing all the slowest water possible.
6/5/16-Bighorn flows are at 5000 cfs.
6/1/16- Yes the water is over 6000 cfs but fish still have to eat. We netted 11 fish in 1 hour yesterday on streamers and 17 or 18 to the net on streamers in 4 hours. That’s very productive streamer fishing. If you like to watch fish chase give us a call and we will set you up. The nymphing has also been good. Takes more work then lower water but the fish are there and ready to eat. Book a professional guide today! 307.267.5161

March Bighorn River Fishing Report:
3/28/16- Fishing on the Big Horn River near Thermopolis has been excellent! We had a boat out today and netted over 40 fish, with eight fish over twenty inches. Browns, Rainbows and Cutthroat were all caught. Fish on this stretch of river are incredibly healthy right now and they are giving an amazing fight to anglers. Midges and Mayflies are present at this time, and in addition to nymphing, dry fly fishing and streamer fishing is productive. Zebra midges, olive mayhems, sow bugs, ray charles, rock worms, eggs, and scuds are all great flies at this time.
3/18/16- Looks like they are going to do their yearly spring flush on the Bighorn on the 20th. Fishing the day after is going to be awesome!

January Bighorn River Fishing Reports Thermopolis Wy:January Bighorn River Fishing Reports Thermopolis Wy:
1/01/16- We had a guide boat out on Thursday January 1st and the fishing was fantastic! The boat brought in 20-25 fish to the net. The best flies were an orange egg, red san juan, and a small hotheaded ray charles in grey. There were hardly anyone else around fishing!
This productive tailwater is one of the best winter fishing options. 820 cfs is the perfect water level, most of the moss is gone, and the crowds are at a minimum. The water temps on the Bighorn have cooled way down so remember to set on the most subtle bumps of the indicator! The Big Horn River has been fishing great with a variety of techniques catching fish.

October Fishing Reports on the Big Horn in Thermopolis Wy:
October 28th-The nymphing, streamer fishing and dry fly fishing have all be great. November and December are great months to catch Trophy Brown Trout!
September Big Horn Thermopolis Fishing Reports
There continues to be considerable moss near the put in at wedding of the waters but this is not greatly impacting fishing with streamers or nymph rigs. With nymph rigs a red san juan worm trailed by black or olive midge patterns has been productive. Other flies to consider include rock worms, scuds, sow bugs, and ray charles. There have been bugs on the water with fish feeding in pods and dry fly fishing can be excellent. Fishing a smaller parachute adams or elk hair caddis have been working well when fish are rising. This is a great time to fish the Big Horn as you can legitimately catch fish with a streamer, dry fly or nymph rig.”
Fish seem to moving into the deeper runs more and more but are still in shallow riffles. So if your nymphing be prepared to set your mini rig to 4 ft from indicator to weight and use 4x tippet and a #4 weight in tin. Or if your going deep then 5 -7 ft and a bb or ab in tin. We are experiencing some of the best Fall dry fly fishing I have seen! When using small dries go with 5x mono floating tippet and try to be stealthy. Make your cast 3-5 ft above the fish and let your fly drift into the rising fish. Remember a slight lift set will do, giving the fish a chance to be on the down turn so you don’t pull it out of his mouth. Streamers fishing has been great! Definitely better on cloudy days!

June Thermopolis Wy Fishing Reports
June 3rd- Big Horn River Update
Big Horn River Fishing Report: The Bighorn in Thermopolis Wy is flowing around 5200 CFS.. Guess what this means? You guessed it. Many of the fish have been forced to the banks meaning the streamer bite is really starting to turn on in the morning and we expect it to get only better as the fish adjust to the high flows. The dry fly fishing wasn’t very good today. The afternoon fishing wasn’t very good either. Inexperienced rowers really need to be careful with this high of water as well as wade fisherman. Do yourself a favor and hire an experienced Big Horn Wy fishing guide from Wyoming Anglers. You won’t regret it!
