A friend returned from a fishing show in Denver recently, and he said that he had heard from many folks that the Bighorn River wasn’t worth fishing. Some bad press about water issues over the past couple years has apparently led to this misinformation. To paraphrase Mark Twain, the report of the river’s death was an exaggeration. We can assure you that the river is very much alive and producing some stunning trout.
We are a few weeks into the season on the Bighorn, excited and looking forward to a fresh start. The spring fishing has been good, and the size of trout being caught is similar to the early years, when the average size was 16 to 18 inches long. The Bighorn has returned to its classic form and is once again the most consistent clearwater fishery in the state of Montana. Here is why:
Over the past few years, Montana’s Bighorn River has experienced higher-than-normal water flows in both spring and summer. Mother Nature threw us a little curve ball, but guides were still able to find plenty of beautiful Bighorn trout every day. Thankfully, the awkward trend in dam management has come to an end, thanks to the critical involvement of the Bighorn River Alliance.
The Bighorn River Alliance has established a technical group, comprising various state and federal agencies, to improve dam management for the health of the Bighorn River. This work group has changed the way the dam forecasts water flows in and out of the Yellowtail Reservoir. In the past, they used only the basic gauges in the mountains to predict snow pack. They are now taking into considerations historical rainfall in the spring, the old snow pack gauges, and, most importantly, the mid- and low-level snowfall in the Bighorn River Basin. All of this ensures that the Bighorn River will remain the incredible fishery that it is now and always will be. For more details visit the report on the Bighorn River Alliance website.
The first thing we have seen this spring is a healthy and productive rainbow trout spawn, uninhibited by aggressive currents flowing over the spawning beds. Next, the vegetation is starting to grow back and with it the billions of insects–including scuds, midges, sow bugs, Baetis, PMDs, Yellow Sallys, and more–that thrive on the numerous grass and moss species in the river. The food source is abundant and creating a healthy habitat for numerous and thriving Bighorn trout. The long term effect of the consistent low flows will be huge returning numbers of brown trout. Smaller fish from the previous year’s spawn will thrive in this food rich, easy living water.

Daily giants on the Bighorn River. It seems that somebody is catching a 22 inch plus trout almost everyday on the Bighorn this springs. The fishing is picking up on the Bighorn River. The water is crystal clear and the flows are at traditional Bighorn River levels. Things are looking good for the 2019 fishing season! #flyfishing #orvisflyfishing #bighornriver #browntrout #fishing #bighornriverresort #montana #montanaflyfishing
The fishing has been consistent this spring , with multiple trout over 24 inches caught every week. The water clarity is remarkable, and the moss and grass are extremely low. Good stream access and consistent river flows make the Bighorn River one of the most scenic and enjoyable rivers in the nation.
