Bighorn Fishing Report

Well here it is...I've had mixed feelings about doing a fishing report here for a number of reasons but for now I'm going to give it a shot due to popular demand.

March 2016

Baetis have been coming off daily since the flush and we are starting to see more and more trout up on them. Fish are concentrating primarily on midge, baetis, sow bugs, annelids and the occasional hellgrammite. The streamer bite is inconsistent but if you stay persistent  the reward is usually a better than average sized trout. Fishing is great and no matter what technique you are into there is something for everyone right now.


April '16-  BWO's are coming off regularly and the trout are on them. Fish are taking nymphs as well as midge, Baetis, annelids, scuds, sow bugs being the most prolific food sources. Occasional terrestrials are getting some nice takes as well as streamers but they are not very consistent. Flows are up a little to 744 cfs.


May '16 - This month has been a bit funky with the rain and run off. The river has turned to chocolate from Buffalo Creek running red from run off and rain. The days however are getting warmer which has been good for the terrestrial fishing. BWOs are still popping along with midge. When the water clears a bit, annelids have been quite productive. Flows have increased two 2000 cfs on May 6th. Big fish water for streamers.


June '16 - Flows are up to 6000 c.f.s. .  Fish are eating but you need to go down and get them. Using long heavy nymph rigs with annelids are your best bet. Sallies are coming off but not much of a factor. Trico's are popping but water is too high and fast for any top water action with any consistency. Streamers will take some fish depending on the day. The moss is becoming more and more of an issue but usually will come off your flies with a few slaps on the water.


July '16/Aug '16 - Flows are down to 1,305 cfs- Fishing is good but there is a lot of grass. Nymphing is the way to go with SJW, rubber legs, sow bugs, caddis and drowned spinners being the most productive . Leeches and crawfish patterns taking fish too. Hoppers are inconsistent but fish will take certain patterns. Sometimes on the twitch sometimes they like it dead drifted.


Sept ' 16 - September is already here and there are signs of fall coming. Fishing is good and getting better on the cooler days. Mornings are great when its hot but by midday it starts to fall off. We are starting to see some more fish up top on Trico's and there are mornings that the hatch is coming down in mats. Most of the trout are taking them subsurface still however. Annelids, sow bugs, Trico spinners, crawfish,  caddis pupae and mayfly nymphs have been food of choice.  Terrestrials are taking some nice fish too but not electric yet. We have been starting to see more naturals on the banks recently. Here is a nice Brown from a trip this week.


Sept/Oct. '16-- Now that September is almost over and the weather is cooling down, the hatches have been prolific. Clouds of Trico's in the morning and blankets of spinners are getting the larger rainbows up on the surface chowing. We are seeing more pods and bows in places that we haven't seen all summer. Also the Pseudo's have been hatching in the late afternoons and early evenings and there is a great spinnerfall later in the day resulting in good top water action for most of the day. There is a lot of grass but it is mostly stringy and easy to slap or cast of for the most part. The flows are low ( around 850 cfs) and river is clearing after getting muddy due to heavy rain. Nymphing can be good in places with annelids, Baetis, drowned spinners ,sow bugs, leeches, crawfish. We are using shorter rigs and still targeting faster water. Streamers can be inconsistent but there are days they are money. Key faster water and work fast at the head of runs in shallow water for some nice Browns. Terrestrials will always work but not necessarily consistently. Go smaller and natural. Try ants, beetles, crickets as well as hoppers. Seeing a lot of naturals on the banks.

February/March '17 -

The fishing is incredible.With the warmer days come very productive days. Trout are on the feedbag again. Midge, sow bugs and annelids are the most prevalent food sources. With the warmer days there has been some run off from the banks making the river off color in places. The Bureau of Reclamation will be dropping the flows and then raising them due to some repairs that are needed. By Wednesday March 1st the flows should be up to 1100 CFS.  Trout are spawning so please be aware of the redds and do not walk on them. Also remember snagging fish is against the law and targeting trout on redds is unethical. 

Late March - Flows are at 2200 cfs right now but not for long. We will be having a flush on the 27th at midnight. The plan is to go to 5000 cfs for a 24 hour period and then decrease flows down to around 3000 cfs. The Bureau of Rec may decide to leave the flows at 5000 for awhile if we get much rain in the meantime. Fishing is fantastic right now. Annelids, sow bugs, Baetis, Midge and eggs are what the trout are keying in on. They are definitely focusing in on certain patterns and the day can be tough if you don't know where they are holding. Getting your rig setup at the right depth and with the right weight is crucial for success. Call Wyoming Adventures at 307-272-6792 to book a trip. 

July 2017 - Its been along couple of months with a high blown out river. However things are getting better with flows dropping from 9000 to 6500 and plans to drop down to 3000 asap. The fish are looking for big meals. Crayfish, annelids, caddis pupae, cranefly larvae and leeches will get there attention. Tricos are hatching but have not amounted to much yet. That will be better as the flows drop. 

Aug '17 - The flows are down to 2200 cfs and the clarity is getting better with plenty of visibility. Trout are keying in mostly on crawdads but will take caddis pupae, annelids, damsel fly nymphs and leeches. Nymphing is still the main tactic but we are seeing a few sippers here and there on tricos and pale evening duns. They are primarily focusing on the spinners. The hatches have not been prolific yet but getting better with cooler weather. Terrestrials are spotty at best even though the banks are covered with them. If you work hoppers all day you will be rewarded with a few willing trout.
