Browns are starting to spawn, so please make sure your not fishing redds. If you see others fishing redds, spread the word and educate them on why it is important and long term effects. We all want a healthy fishery! Shoulder season rates officially go into effect tomorrow! $100 off of Full Days and $75 off of 1/2 days! If you are wanting good fishing, lower rates and less people, then this is the time for you! Keep an eye out for our newsletter, as we are running a Black Friday Special! If you aren’t subscribed to our newsletters, feel free to give our office a call and ask about it! I hope everyone has a fabulous thanksgiving!


Fremont has been fishing well. Tricos in the morning and caddis in the afternoon. Worms and leeches have both been productive as well. Keep an eye out for some noses.

7/10/23- The water is running at 79cfs. It is clear and has been fishing good. Right now the most productive flies are pmds, midges, sallies and caddis. Fremont is a great wading option for those who would rather walk and wade. You can either stick to the meadows or hike through the canyon. Definitely one to visit while your in Casper.

4/26/23- The water is a little off colored but is fishable. The rainbows are still spawning, so please stay off the redds and help preserve our fisheries. Midges, small annelids, leeches and eggs are all the most productive right now. Fremont is a good wading option and sure is scenic.

3/1/19– The fishing is great. Big Rainbows and some good Browns. Leechs, small midges, small annelids, eggs.

11/15/17- Fremont Canyon is fishing very well!

11/2/16-Here is your Freomont Canyon fishing report. It fishing well! It is very low. Not much dry fly  fishing, the streamer fishing can be good and the nymphing is great. A little bit of moss but not bad.

10/3/16-Fishing at Fremont is great right now. There are a lot of fish condensed into small runs. We are using small Midges and some Caddis patterns which are fishing well. Be persistent and cover a lot of water. If you feel like you’re not getting down deep enough, go deeper. A good starting Depth is 6 feet to your weight and you can adjust from there. You’re going to want to be fishing a lot of seems that dump into deep holes. Zebra midges and Mayham’s along with Mcgrubers  are all fishing well.

Fremont Canyon Winter fishing Report: January

1/17/16 Fremont Canyon fishing has been pretty good. Not a ton of fish but all nice fat fish. As soon as I went with 4x tippet and small bugs I started getting many more fish. Size 18-20 black midges & bead headed pheasant tails did the trick. Remember that this time of year most of the fish are going to be in the deeper runs and tailouts. The fish in here are more finicky than the Grey Reef. Make sure your drifts don’t have any drag. Cast up high and shallow in the run to give your flies time to get down to reach the fish you are targeting in the deeper water.

1/01/16 Fremont Canyon Fishing Report: Fly fishing in Fremont Canyon has been pretty good! The water is EXTREMELY Clear so be stealthy with your shadow and casting.  Nymphing, remains solid with midges, leechs, red san juans, and rock worms. But if  you ever have a hard time catching fish in Fremont ditch the big bugs and go small like 18-20.  And lighten up your tippet. I haven’t found one particular  fly to work better than another as long as your weight, depth and drift are correct.  You don’t need to dredge, the fish will find your flies! A 4-6 ft rig seems to be the ticket. Good luck!

November 11th- Fremont Canyon Fishing Report

Nov 11th Fremont Canyon Winter Report

Fremont Canyon is fishing very will with small bugs and 4x tippet.  Or go big with brown ps leech tied to 3x with a midge dropper.

Fly fishing in Fremont Canyon has been nothing short of superb lately with lots of dry fly action. The water is EXTREMELY Clear and the ability to sight fish these large browns & rainbows is very possible. Dry fly fishing has also been incredible! Fishing a black #20 Sprout Midge dry fly seams to be working for all the rising fish. I’ve been fishing 9′ 5x leaders on dries. Lot’s of quality fish up eating dries as well. Nymphing, remains solid with midges, leechs, and leeches. I haven’t found one particular fly to work better than another as long as your weight, depth and drift are correct. You don’t need to dredge, the fish will find your flies! The fish in Fremont are Looking up so fishing a nymph rig 1-3 feet indicator to split will work just fine and keeps your flies clean.May Fremont Canyon Fishing Reports

February Fremont Canyon Fishing Reports

February 7th- Update From Guide, Matt Haupt
Fremont Canyon Fishing Report- Amanda and I went out with a couple of friends to Fremont Canyon Saturday morning to check it out.   We fished a section higher up, about half of a mile down from Pathfinder.   Time was short, so we found a nice run and fished it for about an hour and a half or so.   Amanda took this nice Rainbow on a brown hot head leech,  and a few similarly sized fish were had on a size 16 tan scud, and 14 red rock worm.  Around 10 am we did spot some surface activity-slower boils, backs coming out of the water, probably taking midges just subsurface.  We didn’t fish it as hard as I like, the wind was getting bad and this was more of a leisure trip than most so we decided to head back into town for some Mexican food. Let’s go fishing!
